There are many reverse proxy solutions that enable configuring SSL certificates, both in the home lab and production environments. Most have heard about Traefik reverse proxy that allows you to pull LetsEncrypt certificates for your domain name automatically. However, there is another solution that provides a really great GUI dashboard for managing your reverse proxy configuration and LetsEncrypt…

Does L-Tech have any insurance in there programing to ensure there software isn't used by malicious (well, i guess in this case more malicious) actors for traditional corporate crime ala corporate espionage? Also, what kind of security is in place (if any) to insure valuable L-Tech equipment cant be compromised by malicious agents outside of working hours?

I need the tech knowledgeable people to help me with what the exact methods would be but they are extremely serious about securing their program in multiple ways

1. Software is proprietary and heavily encrypted

2. It takes a huge amount of data or access to L-Techs cloud software to run the complex and purposefully non-optimized software. OSeditor looks simple on the user end but is constantly iterated on and bloated with tweaks and from the complexity of successfully interfacing w an outside entities mind

3. The install requires multiple written guides that explain things not available in the software itself, so even if you crack the program, you also need the internal literature to operate it correctly. I think many unauthorized users are stopped by accidentally hypnotizing themselves

4. There are some basic commands built into the hypnosis and a handful of top secret number combinations that can affect an OS without their admins approval.

5. They have government support and support from other large corporate entities to discourage the spread of information about OSeditor

6. They work hard to deincentivize corporate espionage resulting from employee dissatisfaction or disloyalty... the perks are very high and if anyone seems like a risk for disloyalty, you can always tweak them a little... Which can make them into a very useful double agent

Its still not impossible for hackers to mess with it ofc... there's always people working hard to undermine L-Tech despite all the hoops... many T4T yuri hacker couples

Went and rewatched a recording of KBOOM I did (mostly for personal reference) and. It is an interesting detail to me, because of the whole "Welcome, Agent Phoenix" thing on the cabin screen, it leads me to believe that there was something going on there that just. Doesn't get covered except indirectly in various lines.

Roxana says she doesn't have access to the lava generator systems in her cabin, which. she does have access to a lot of stuff in her cabin that Phoenix just doesn't have, but it's interesting that that gets mentioned, because those lava generators get used Constantly. In terms of the lava generators alone and the ability to move the lava between the cabins, Phoenix's cabin almost behaves like an admin cabin, in a sense.

It also has a forge, and a parameters panel. Roxana might have the parameters panel on the other cabins, but given she does parameters when she's in the central...tower area, I'm unsure.

The screwdriver is something Phoenix probably brought, but the metal just kind of laying around, and the forge templates, those were probably there from the start, along with the cans of butane and...liquid nitrogen iirc. And the welding mask.

This is all probably mostly to make the level doable, but there's a lot more direct interaction between Zor and Phoenix in the third game, which. if there's that much direct interaction, it just strikes me as a bit odd that it's always. pretty convenient. The shield generator is just left in the underwater lab, free for the taking. With a demonstration of the kinesium chain destabilization and a guide on how to use the shield generator.

If I read this as pure like. Story wise. Not bothering with the game needing to be beatable or fair:

-The shield generator is just left behind in the underwater lab, which...seems like an odd enough decision on its own. It can block kinesium explosions, that feels like something that'd be kept under pretty tight security, and Zor knew that Phoenix would be going to the lab anyway considering they leave a tape. And instructions. And a demonstration. Yes the demonstration was a power play but it was a demonstration of how their Big Evil Plan worked.

-Zor does slip a little threat in the tape recording, to be fair ("know whatever end you meet"), but. In all honesty I mostly read that as saying it for the sake of keeping up appearances. Doesn't make much sense if they actually expected Phoenix to die down there. Even with the squid.

-Zor sets up the explosion at Roxana's factory, which kills all her robots and was apparently intended to kill her. They seem mildly surprised when she's alive in KBOOM, though they shake it off pretty quickly. It's entirely possible Phoenix was "supposed" to go into KBOOM with the shield generator, given it was just left free for the taking during Hot Water.

-Phoenix's cabin in KBOOM has the ability to control and use the lava generators, a forge for making various bits and pieces, metal for the forge, and...very conveniently everything they'd need to interface with the destabilizers. This could be chalked up to them getting lucky and getting in just the right cabin, but. well.

and oh, huh. the laser grid relies on a set of gears that have a very easy cover to remove. and hey would you look at this can of convenient liquid nitrogen, or this screwdriver, or-

-Everything about Zor's little speech at the end weighs on my mind constantly. I've mentioned their tone before so I'm going to skip that. There's a very specific line in their final speech I'd like to dwell on for a moment, if you'll pardon me.

That being this line.

I'm going to play semantics for a second because god damn if I didn't take a lot of classes in high school where wording was a Constant Thing.

Obviously Roxana believed her robots were better than Phoenix for most of the game, that's not what I'm questioning. I'm questioning why the word "fooled" specifically. Not "you convinced Prism to believe in you" or "you made Prism believe in you", it's just. fooled.

Zor has obviously seen Phoenix pull their plans apart like string cheese on multiple different occasions by this point, and seems to base various plans on the fact that they'll survive various trials, so I don't read this as them doubting Phoenix's skills or abilities. What they're doubting, I'm not sure exactly.

I'm putting this under a disclaimer: It's entirely possible that my own personal interpretation of Phoenix is going to have some amount of influence here. Maybe everything I'm reading out of this is BS and I just have confirmation bias, but this section did make me adjust my interpretation of Phoenix somewhat, so there's influence going both ways.

I will write out the full speech, just for convenience:

"So you fooled Prism into believing in you. Well, even the great Agent Phoenix will eventually burn out. Believe me when I say there is nothing left in the Agency worth saving. I would know. Be seeing you."

The way this reads to me does not necessarily imply "you're going to die and lose one of these days", because there's a lot of other stuff going on here.

There's the fact that Zor uses the phrasing of "burn out" to refer to Phoenix, because. burning is sort of what phoenixes do, like that's their whole Thing. Split in half, I could probably read it as saying, effectively, either "one of these days, you'll die" or "you should ditch the Agency before they get you killed", and just take it at that, but without that split, neither of those really feel. complete.

Maybe they're just trying to throw Phoenix off, unsettle them a bit, but this specific little monologue reads as something more to the effect of "good job fooling people (possibly even yourself) into thinking you're just the Agency's little back-pocket weapon, but you know they're kind of worthless, right? See ya later, "phoenix"" it's a very crass and flat way of writing out the way i interpreted it, but it gets the point across.

Maybe Zor knows more about Phoenix than they let on. Maybe they're just talking bullshit and trying to get under Phoenix's skin. Maybe it's both. Maybe it's neither, and I'm overthinking it, and they do genuinely just think Phoenix isn't as good as they seem. But. Yknow.

They wanted Phoenix captured alive in the second game. If Phoenix is really that much a thorn in their side, why not do what Juniper suggested and just shoot them while they were unconscious? Phoenix was vulnerable after they got captured. Vulnerable and practically in Zor's hands. The Peace Summit was apparently a plan "years in the making", but they didn't. Stop Phoenix. What Juniper did was the equivalent of sticking a cat in a carrier and telling it to stay.

President Donald Trump has raised logging quotas in the United States by 25 percent as a way to prevent fires. This also comes as the Trump administration is looking to increase lumber production.

The US Department of Agriculture issued an emergency order on Friday to increase the amount of lumber being harvested in the US by 25 percent, the San Francisco Chronicle reported. The directive was announced by USDA Secretary Brooke Rollins, who made a special emphasis on harvesting lumber from California in order to prevent wildfires.

“National Forests are in crisis due to uncharacteristically severe wildfires, insect and disease outbreaks, invasive species and other stressors,” the order stated, later adding, "These threats-combined with overgrown forests, a growing number of homes in the wildland-urban interface, and more than a century of rigorous fire suppression- have all contributed to what is now a full-blown wildfire and forest health crisis."

Breitbart reported that the increase in lumber may not just be for reducing fires, but also to increase production of lumber in the US because production "is likely to increase the supply of lumber and head off potential price increases due to tariffs on Canadian lumber, which could have a cascading effect on the American construction industry.”

The order also stated, "The United States has an abundance of timber resources that are more than adequate to meet our domestic timber production needs, but heavy-handed federal policies have prevented full utilization of these resources and made us reliant on foreign producers. It is vital that we reverse these policies and increase domestic timber production to protect our national and economic security."

192.168.1.250 Netgear Setup: A Beginner’s Guide

The netgear extenders are widely used by many of the networking users to create a reliable network. Netgear extender devices are known for their performance and stable network. Setting up the extender device is not a daunting task if you are aware of the setup process. In this article we are going to elaborate in detail how you can perform 192.168.1.250 Netgear Setup using the web. Web based setup method is the most reliable way to add the netgear extender into your existing network. Gather the important details and configure any model of netgear wireless range extender device. Scroll up the page and read the information till the last to boost up your network. 

Unboxing The Extender

Unboxing the wireless range extender is the first step of the 192.168.1.250 Netgear Setup. In the box you will find an extender along with power adapter, user guide and ethernet cable (optional). You need all such items for the setup process. In addition to these items you also need host router network details, working internet connection, electric power socket, and computer/ laptop device. 

Placement 

Second step is placement of the device. Proxy placement is needed for the setup. Put the device closer as possible. Also there is no signal interface closer to the router & extender device. 

Boot Up 

Next step of the process is boot up. For booting up you have to use the power adapter you got with the extender. In case your device is a wall plug compact design device then you have to directly connect it with a wall outlet. Boot process might take around 1 to 2 minutes. Before proceeding further towards 192.168.1.250 Netgear Setup using the web, wait for LED lights to stabilize. 

Connect To Extender Network

Step ahead and connect the extender device to the client device using any of the given methods:

Ethernet: Use the ethernet cord you got with the range extender and connect the extender with the client device. Inject the cord’s one end into the ethernet port of the extender and other in the client device ethernet port. Make sure the connection is secured.

Wireless: Using the wireless network of ethernet you can establish a connection. Check out the device label to know the default SSID & password. Use your client device and run a scan for available wireless networks. Enter the details and connect the devices.

Access 192.168.1.250 Netgear Setup Page

Now you have to access 192.160.1.250 netgear setup page by follow the given steps:

Launch google chrome or any other similar browser. 

Thereafter, mention 192.168.1.250 IP in the URL bar. 

A new page appears where you have to provide default information. 

Enter admin and password in the fields. 

Further press login and netgear installation assistant will guide you.

Configure Extender

Once you get access to the configuration page, choose the language first and then your router’s network name. Choose next and enter the password on the screen. Further click on connect option and then next.

Secure Network

Now you have to secure the wireless network by creating an SSID & password for your extender network. Also make changes in the admin account user details. This step is important to keep your existing network secure.

Update Firmware

Afterwards, you need to look for the firmware version. In case the firmware is outdated then you should install the latest version. For installation you can opt for an online update option and follow the prompts. You can update the firmware manually also by downloading it from the official portal of netgear. 

Finalize Setup

Finalize the setup by choosing the submit button once you made all the important changes in the network. Review the changes you made to verify every step. Note down the extender security details you have created and keep them secure. Submit the changes and then you can step further to reposition the device.

Reposition The Extender

Repositioning the extender is a very important step to optimize the network performance. Unplug the extender from the proxy position. Search for a midway position (from the router and the area where the dead spot was). Then plug it in again to the power at the new position. Wait for the device to boot up and monitor the router LED on your extender device. If it’s green then the position is perfect. On the contrary if it turns amber or red then relocate it.

Test New Network

Lastly, test the new network using a wireless handset. Using the new SSID & password connect the device with the extender network and browse, stream or play online to check speed.

Conclusion

Lastly, I would like to rest my words by saying that the 192.168.1.250 Netgear Setup process is a super easy task. By following the above mentioned step by step breakdown of the extender setup process, anyone can configure the extender easily without a tech expert. Setting up an extender device will boost your existing network signal strength and terminate the dead spots from your home or office area.

Lifesaving Tech with Hidden Risks: Medical IoT Devices

Hey, so… what even are Medical IoT Devices?

Okay, let’s start with the basics. Medical IoT (Internet of Things) devices are basically smart gadgets that help doctors and patients manage health in real-time. Think of them as the Fitbits of the medical world, but way more advanced and sometimes implanted inside your body.

Here’s a quick rundown of the most common types:

Wearables: Smartwatches, glucose monitors, patches that track your vitals.

Implantables: Pacemakers, insulin pumps, neurostimulators that keep your heart ticking, your blood sugar in check, your brain functioning properly respectively.

Hospital Gear: Things like infusion pumps, ventilators, or MRI machines that are connected to the hospital’s network.

These devices are amazing because they can send data straight to your doctor, so they can monitor you without you having to camp out in a hospital bed. But (and there’s always a but), this connectivity comes with a price: security risks.

Wait, How Can a Pacemaker Get Hacked?

Okay, so let’s get into the nitty-gritty of how these devices can be exploited. It’s not just about “hackers being hackers”, there are specific technical flaws that make these devices vulnerable.

1. Encryption (or Lack Thereof)

Encryption is like a secret code that scrambles data so only authorized parties can read it. For medical IoT devices, encryption is crucial because they’re transmitting sensitive health data. But here’s the problem: not all devices use strong encryption.

What’s Happening: Some devices send data in plaintext (unencrypted) or use weak encryption algorithms that can be cracked by hackers.

Example: If an insulin pump sends unencrypted data to a doctor’s computer, a hacker could intercept it and alter the dosage instructions, potentially causing harm to the patient.

2. Authentication Protocols

Authentication is how a device verifies that someone (or something) is who they claim to be. Think of it like a password or a fingerprint scan. But many medical IoT devices use weak or default authentication methods.

What’s Happening: Devices might use hardcoded passwords (e.g., “admin” or “1234”) or lack multi-factor authentication (MFA).

Example: A hacker could use a default password to gain access to a hospital’s network of infusion pumps and change their settings, leading to incorrect medication doses.

3. Specific Attack Vectors

Let’s break down how a hacker might exploit a vulnerability in a real-world device, like an insulin pump:

Step 1: Reconnaissance

The hacker scans for vulnerable devices connected to the internet. Many medical IoT devices are discoverable through tools like Shodan, a search engine for connected devices.

Step 2: Exploiting Weak Authentication

The hacker tries default credentials or brute-forces the password to gain access to the insulin pump’s control interface.

Step 3: Intercepting or Altering Data

Once inside, the hacker can intercept data (e.g., blood sugar levels) or send malicious commands (e.g., delivering an incorrect insulin dose).

Step 4: Covering Their Tracks

The hacker might delete logs or use encryption to hide their activity, making it hard for healthcare providers to detect the attack.

This isn’t just theoretical. Researchers have demonstrated these attacks in controlled environments to highlight the risks.

Real-Life Examples That’ll Make You Side-Eye Your Smartwatch

Let’s talk about some real-world incidents that’ll make you go, “Oh no, this is actually happening”:

The St. Jude Medical Hack (2017): Researchers found that certain implantable cardiac devices had vulnerabilities that could let hackers mess with the device’s functionality. Imagine your pacemaker getting hacked and delivering random shocks to your heart. Terrifying, right?

The Hacked Pacemakers (2018): In a chilling demonstration, the FDA confirmed that nearly half a million pacemakers were vulnerable to hacking. Hackers could potentially alter the device’s settings, drain its battery, or even deliver fatal electric shocks. Abbott (the manufacturer) had to issue a firmware update to patch the vulnerability, but not all devices could be updated remotely, leaving some patients at risk.

Ransomware in Hospitals (2020): A ransomware attack on a German hospital disrupted its systems, and a patient who needed urgent care died because the hospital couldn’t operate properly. This wasn’t a direct attack on a medical device, but it shows how vulnerable healthcare systems are.

These aren’t just hypothetical scenarios. They’re happening, and they’re putting lives at risk.

Who’s Behind These Attacks?

Not all hackers are created equal. Here’s who might be targeting medical IoT devices:

Cybercriminals: They’re in it for the money. They might steal patient data to sell on the dark web or lock down hospital systems with ransomware.

Nation-States: Some governments use cyberattacks as a form of espionage or warfare. Targeting medical devices could be a way to destabilize a country or gather intel.

Hacktivists: These are hackers with a cause. They might attack a hospital to make a political statement or expose security flaws.

So… What Can We Do About It?

The good news is that there are ways to protect medical IoT devices. It’s not a lost cause...yet. Here’s what needs to happen:

1. For Manufacturers:

Stop Using Default Passwords: Imagine leaving your front door unlocked with a sign that says, “Welcome, hackers!” That’s what default passwords like “admin” or “1234” do. Manufacturers need to make sure every device has a unique, strong password right out of the box.

Lock Down Data with Strong Encryption: Encryption is like putting your data in a safe. Manufacturers should use the strongest locks available (like AES-256 encryption) to keep patient information safe from prying eyes.

Test for Weak Spots Before Selling Devices: Before releasing a device, manufacturers should hire ethical hackers to try and break into it. This is called penetration testing, and it helps find and fix vulnerabilities before they can be exploited.

Follow the Rules (FDA Guidelines): The FDA has a set of rules for making sure medical devices are secure. Manufacturers need to follow these guidelines to keep patients safe.

2. For Hospitals and Doctors:

Keep Medical Devices on a Separate Network: Think of it like having a VIP section at a concert. Hospitals should keep medical devices on their own secure network, away from the rest of the hospital’s systems. This makes it harder for hackers to sneak in.

Watch for Suspicious Activity: Hospitals should use tools that act like security cameras for their networks. These tools, called intrusion detection systems (IDS), can spot hackers trying to break in and alert the staff.

Train Staff to Spot Cyber Threats: Doctors and nurses are experts at keeping patients healthy, but they might not know much about cybersecurity. Hospitals should train their staff to recognize and respond to cyber threats, like phishing emails or suspicious device behavior.

3. For Patients:

Keep Your Device’s Software Up to Date: Just like you update your phone to get the latest features and security fixes, you should update your medical devices. These updates often include patches for known vulnerabilities.

Avoid Public Wi-Fi: Public Wi-Fi is like shouting your secrets in a crowded room, anyone can listen in. If your medical device connects to the internet, make sure it’s using a secure, private network.

Use a VPN for Extra Security: A VPN is like a secret tunnel for your internet traffic. It keeps your data safe from hackers, especially if you’re accessing medical information remotely.

The Bigger Picture: Why This Matters for Everyone

Okay, so this isn’t just a tech issue. It’s a public health issue. Vulnerable populations, like the elderly, people with chronic illnesses, or those who rely on medical devices to stay alive, are often the most at risk. And let’s be real: it’s not fair that some people are more at risk than others just because of their income or where they live.

Here’s the thing: wealthier patients might have access to the latest, most secure devices or private healthcare, while lower-income patients could be stuck with outdated or less secure options. Imagine needing a pacemaker but only being able to afford one that hasn’t been updated in years and is vulnerable to hacking. That’s not just unfair; it’s dangerous. And it’s something we need to fix as a society.

But it’s not just about money. There’s a bigger ethical responsibility here. Manufacturers need to prioritize patient safety over profits. That means investing in strong encryption, regular updates, and rigorous testing before releasing devices. And governments? They need to step up and enforce stricter cybersecurity standards to hold manufacturers accountable.

And let’s talk about the legal side for a sec. Laws like the FDA’s cybersecurity guidelines and the EU’s Medical Device Regulation are supposed to keep us safe, but they often lag behind the fast pace of tech advancements. Plus, there’s the whole question of liability: if a hacked device harms someone, who’s responsible? The manufacturer? The hospital? The patient? It’s a legal gray area that needs clarity.

Oh, and it’s not just a problem in wealthy countries. In developing nations, where healthcare systems are already stretched thin, a cyberattack on medical devices could be catastrophic. Access to secure healthcare is a basic human right, and we’re failing to protect that right when we ignore these vulnerabilities.

So yeah, this isn’t just about fancy gadgets or tech jargon. It’s about people’s lives. It’s about making sure that everyone, no matter their income or where they live, has access to safe, secure healthcare. And that’s something we all need to care about.

Final Thoughts

Medical IoT devices are a game-changer for healthcare, but their security flaws are a ticking time bomb. We can’t afford to ignore this issue, not when lives are on the line. Whether you’re a patient, a doctor, or just someone who cares about tech and ethics, it’s time to start paying attention.

So, the next time you hear about a smart pacemaker or a glucose-monitoring app, remember: with great tech comes great responsibility.

TL;DR

Medical IoT devices are amazing but have serious security flaws. Hackers can exploit these flaws to harm patients, and we need better safeguards to prevent this. Everyone (manufacturers, hospitals, and patients) has a role to play in making these devices safer.

Cyberpunk and Hypnok1nk

Chronic pain hit me young, and I've pretty much always had a fluid sense of identity (trending femme, but fluid nonetheless). So it's not really surprising I've always been fascinated by the idea of full-body-replacement transhumanism, Ghost in the Shell style.

Like, I don't want to be in pain anymore, but that's just a fact of the meat I'm trapped in. It's going to hurt, no matter what, for the rest of my life. It'd be nice to keep on existing but feel good instead, y'know?

And sometimes I might want to be smol and cute so I can be someone's little spoon and feel safe in their arms, while other times I might want to be a seven foot tall amazon with a giant dick. I might want both of these things alternately several times a week, and it'd be great for that to be possible.

But there's the classic thing people talk about in scifi where full-body-replacement cybernetics are a thing. The brain-computer interface. That bit where you'd (in theory) have to expose every single thing that you are to an outside connection to hook everything up.

It'd be a huge security risk, where people could turn you into a passenger in your own body, or delete your childhood and replace it with another set of memories as easily as you can move files around on your PC. And maybe they don't want you to be able to stop them, so they lock you out of your own systems while they keep hacking away at your very personhood until all that's left happily agrees that you walked off the assembly line for brothel dolls only a few hours ago and expecting you to read or have opinions would just be silly.

And yeah, like, that's a nightmare scenario, right?

But also, that's so hot, right?

But it never really occurred to me that it's also kinda the same dynamic with hypnokink. It's basically just handing your tist - whether they're an actual person or just a hypnofile you like to listen to - the keys to the kingdom. Letting them root around in your file system, ripping some folders out, dropping new media in, changing some configs.

It never occurred to me that maybe my hypnokink might have partially come from just going "y'know what, fuck it, I want a hacker to turn me into their joytoy". If I'm happy with the idea of someone getting into my head and ruining me, then the only drawback of full-body-replacement cybernetics is that it's not here yet.

I'm ready to have someone reduce my clock speed to a crawl, wipe my memory, swap my language database from English(US) to English(Grade School Dropout Bimbo), delete my optical character recognition software, and reduce me from Admin to Guest user privileges. Fuck playing it safe, I'll intentionally put myself in the same chassis as last gen's most popular sex dolls, and while most people are gonna worry about random people tapping in to their hardline ports, I'm just gonna leave my wireless wide open with no password and no firewall and accept the inevitable.

A ditz can dream...

On one hand, having a group chat of some sort to discuss hero-ing shenanigans seems useful. On the other, using Discord or even a text group chat seems like a pretty good way for some tech company to get their hands on a whole bunch of secret identities. Do superheroes have a proprietary app for this sort of thing? Or do they have another solution?

For the JLA and Titans-related heroes, Cyborg's hacking powers render this a total non-issue. On the client end, they use the same texting and messaging apps as everyone else, with a few added bits and bobbles of interface.

On the server end, software that Cyborg set up (took him about 5 minutes) casually intercepts every message they send before it reaches any servers corporations could extract data from, redirects to a private, secure instance of the same chat/texting software (getting Facebook's total source code without authorization is about 0.02 seconds of effort for him), also redirects anyone else in the same chatspace to the same private server, then filters all the messages for sensitive info (there's ways people can flag their own messages) before hacking back into the corporate servers to re-insert a record of some messages they would expect to see as if their own servers had handled everything, so even if admins try to investigate they won't be able to tell who's using the pirated chat instance to ban them.

It's all very complicated from a human perspective but it's all happening totally automatically in real time so it doesn't really matter. The end result is the Titans just have a regular old Discord server that, as far as Discord the company is concerned, doesn't exist, but they can still invite people to who are using regular Discord accounts or chat from their accounts on other normal servers, and other apps are all similarly seamless and convenient.

The Avengers have basically an ultra-high-end spy version of Signal (the app, not Batman's latest son). At first they were just using SHIELD messaging software but after not too long Stark made his own. But the way it's set up, not even Stark has access to all the messages that are sent to anyone besides him. During Civil War he tried to shut down the whole service so the other side couldn't use it, and failed. He just made it too secure and autonymous. Unless someone has the app open and is currently looking at what he wants to see, not even Cyborg could extract chatlogs from it.

The X-Men, X-Force, and X-Factor are basically left out in the cold and forced to use a combination of regular services (some encrypted like Signal) and, when available, and only for the people who agree to it, telepathic chatrooms.

Whoever is "hosting" a telepathic chatroom isn't consciously aware of the messages being subconsciously relayed in real time, but, there's nothing to stop them browsing if they get curious, and as soon as they need to focus and use their powers on anything else strenuous or with stakes, the whole thing shuts down. But the chatlogs being stored in the literal memories of the people in them, that only prevents new messages from being sent for a while (and from being able to literally visually see it), and if the telepathic chatrooms need a new "host" to run it, little is lost in the hand-off.

Of course all of that is just about text chat. Earpiece comms are fairly standard among superheroes, so a lot of communication happens over comms voice calls/recorded voice messages, and that's its own whole topic.

#Playstation7 Security backend FireWall Dynamic Encryption, NFT integration CG’s and Online Store, Game download, installation and run processes.

Creating a comprehensive backend system for a console that integrates security, encryption, store functionality, NFT integration, and blockchain encoding is an extensive task, but here’s a detailed outline and code implementation for these components:

1. Security and Firewall System with Dynamic Encryption

The security system will need robust firewalls and periodic encryption mechanisms that update dynamically every 5 minutes and every 30th of a second.

1.1 Encryption Structure (Python-based) with Time-Based Swapping

We’ll use the cryptography library in Python for encryption, and random for generating random encryption keys, which will change periodically.

Encryption Swapping Code:

import os

import time

import random

from cryptography.fernet import Fernet

class SecuritySystem:

def __init__(self):

self.current_key = self.generate_key()

self.cipher_suite = Fernet(self.current_key)

def generate_key(self):

return Fernet.generate_key()

def update_key(self):

self.current_key = self.generate_key()

self.cipher_suite = Fernet(self.current_key)

print(f"Encryption key updated: {self.current_key}")

def encrypt_data(self, data):

encrypted = self.cipher_suite.encrypt(data.encode())

return encrypted

def decrypt_data(self, encrypted_data):

return self.cipher_suite.decrypt(encrypted_data).decode()

# Swapping encryption every 5 minutes and 30th of a second

def encryption_swapper(security_system):

while True:

security_system.update_key()

time.sleep(random.choice([5 * 60, 1 / 30])) # 5 minutes or 30th of a second

if __name__ == "__main__":

security = SecuritySystem()

# Simulate swapping

encryption_swapper(security)

1.2 Firewall Setup (Using UFW for Linux-based OS)

The console could utilize a basic firewall rule set using UFW (Uncomplicated Firewall) on Linux:

# Set up UFW firewall for the console backend

sudo ufw default deny incoming

sudo ufw default allow outgoing

# Allow only specific ports (e.g., for the store and NFT transactions)

sudo ufw allow 8080 # Store interface

sudo ufw allow 443 # HTTPS for secure transactions

sudo ufw enable

This basic rule ensures that no incoming traffic is accepted except for essential services like the store or NFT transfers.

2. Store Functionality: Download, Installation, and Game Demos

The store will handle downloads, installations, and demo launches. The backend will manage game storage, DLC handling, and digital wallet integration for NFTs.

2.1 Download System and Installation Process (Python)

This code handles the process of downloading a game, installing it, and launching a demo.

Store Backend (Python + MySQL for Game Listings):

import mysql.connector

import os

import requests

class GameStore:

def __init__(self):

self.db = self.connect_db()

def connect_db(self):

return mysql.connector.connect(

host="localhost",

user="admin",

password="password",

database="game_store"

)

def fetch_games(self):

cursor = self.db.cursor()

cursor.execute("SELECT * FROM games")

return cursor.fetchall()

def download_game(self, game_url, game_id):

print(f"Downloading game {game_id} from {game_url}...")

response = requests.get(game_url)

with open(f"downloads/{game_id}.zip", "wb") as file:

file.write(response.content)

print(f"Game {game_id} downloaded.")

def install_game(self, game_id):

print(f"Installing game {game_id}...")

os.system(f"unzip downloads/{game_id}.zip -d installed_games/{game_id}")

print(f"Game {game_id} installed.")

def launch_demo(self, game_id):

print(f"Launching demo for game {game_id}...")

os.system(f"installed_games/{game_id}/demo.exe")

# Example usage

store = GameStore()

games = store.fetch_games()

# Simulate downloading, installing, and launching a demo

store.download_game("http://game-download-url.com/game.zip", 1)

store.install_game(1)

store.launch_demo(1)

2.2 Subsections for Games, DLC, and NFTs

This section of the store manages where games, DLCs, and NFTs are stored.

class GameContentManager:

def __init__(self):

self.games_folder = "installed_games/"

self.dlc_folder = "dlcs/"

self.nft_folder = "nfts/"

def store_game(self, game_id):

os.makedirs(f"{self.games_folder}/{game_id}", exist_ok=True)

def store_dlc(self, game_id, dlc_id):

os.makedirs(f"{self.dlc_folder}/{game_id}/{dlc_id}", exist_ok=True)

def store_nft(self, nft_data, nft_id):

with open(f"{self.nft_folder}/{nft_id}.nft", "wb") as nft_file:

nft_file.write(nft_data)

# Example usage

manager = GameContentManager()

manager.store_game(1)

manager.store_dlc(1, "dlc_1")

manager.store_nft(b"NFT content", "nft_1")

3. NFT Integration and Blockchain Encoding

We’ll use blockchain to handle NFT transactions, storing them securely in a blockchain ledger.

3.1 NFT Blockchain Encoding (Python)

This script simulates a blockchain where each block stores an NFT.

import hashlib

import time

class Block:

def __init__(self, index, timestamp, data, previous_hash=''):

self.index = index

self.timestamp = timestamp

self.data = data

self.previous_hash = previous_hash

self.hash = self.calculate_hash()

def calculate_hash(self):

block_string = f"{self.index}{self.timestamp}{self.data}{self.previous_hash}"

return hashlib.sha256(block_string.encode()).hexdigest()

class Blockchain:

def __init__(self):

self.chain = [self.create_genesis_block()]

def create_genesis_block(self):

return Block(0, time.time(), "Genesis Block", "0")

def get_latest_block(self):

return self.chain[-1]

def add_block(self, new_data):

previous_block = self.get_latest_block()

new_block = Block(len(self.chain), time.time(), new_data, previous_block.hash)

self.chain.append(new_block)

def print_blockchain(self):

for block in self.chain:

print(f"Block {block.index} - Data: {block.data} - Hash: {block.hash}")

# Adding NFTs to the blockchain

nft_blockchain = Blockchain()

nft_blockchain.add_block("NFT1: Digital Sword")

nft_blockchain.add_block("NFT2: Magic Shield")

nft_blockchain.print_blockchain()

3.2 NFT Wallet Transfer Integration (Python)

This script will transfer NFTs into wallets or digital blockchain systems.

class NFTWallet:

def __init__(self):

self.wallet = {}

def add_nft(self, nft_id, nft_data):

self.wallet[nft_id] = nft_data

print(f"Added NFT {nft_id} to wallet.")

def transfer_nft(self, nft_id, recipient_wallet):

if nft_id in self.wallet:

recipient_wallet.add_nft(nft_id, self.wallet[nft_id])

del self.wallet[nft_id]

print(f"Transferred NFT {nft_id} to recipient.")

# Example usage

user_wallet = NFTWallet()

user_wallet.add_nft("nft_1", "Digital Art Piece 1")

recipient_wallet = NFTWallet()

user_wallet.transfer_nft("nft_1", recipient_wallet)

4. CG (Computer Graphics) Storage for Cutscenes and Artwork

4.1 Storing and Retrieving CG Assets

This system stores CG assets (cutscenes, artwork, etc.) for later viewing and reminiscing.

class CGStorage:

def __init__(self):

self.cg_folder = "cg_assets/"

os.makedirs(self.cg_folder, exist_ok=True)

def store_cg(self, cg_id, cg_data):

with open(f"{self.cg_folder}/{cg_id}.mp4", "wb") as cg_file:

cg_file.write(cg_data)

print(f"CG {cg_id} stored.")

def retrieve_cg(self, cg_id):

with open(f"{self.cg_folder}/{cg_id}.mp4", "rb") as cg_file:

return cg_file.read()

# Example usage

cg_storage = CGStorage()

cg_storage.store_cg("cutscene_1", b"CG video data")

cg_data = cg_storage.retrieve_cg("cutscene_1")

Summary of the System:

1. Security: Dynamic encryption swaps with regular firewall management.

2. Store: Handles game downloads, installations, and demo launches, including storage for games, DLC, and NFTs.

3. NFT Integration: A blockchain-based system for NFT encoding and wallet transfers.

4. CG Storage: Storing and retrieving game cutscenes and artwork for later viewing.

This framework is scalable and can be extended as the console ecosystem grows. Each component works independently but can be integrated into a larger gaming console backend system.

Introduction

The IT field is vast, and Linux is an important player, especially in cloud computing. This blog is written under the guidance of industry experts to help all tech and non-tech background individuals secure interviews for roles in the IT domain related to Red Hat Linux.

File Permissions

Briefly explain how Linux file permissions work, and how you would change the permissions of a file using chmod. In Linux, each file and directory has three types of permissions: read (r), write (w), and execute (x) for three categories of users: owner, group, and others. Example: You will use chmod 744 filename, where the digits represent the permission in octal (7 = rwx, 4 = r–, etc.) to give full permission to the owner and read-only permission to groups and others.

What is the purpose of the umask command? How is it helpful to control default file permissions?umask sets the default permissions for newly created files and directories by subtracting from the full permissions (777 for directories and 666 for files). Example: If you set the umask to 022, new files will have permissions of 644 (rw-r–r–), and directories will have 755 (rwxr-xr-x).

User and Group Management:

Name the command that adds a new user in Linux and the command responsible for adding a user to a group. The Linux useradd command creates a new user, while the usermod command adds a user to a specific group. Example: Create a user called Jenny by sudo useradd jenny and add him to the developer’s group by sudo usermod—aG developers jenny, where the—aG option adds users to more groups without removing them from other groups. 

How do you view the groups that a user belongs to in Linux? 

The group command in Linux helps to identify the group a user belongs to and is followed by the username. Example: To check  user John’s group: groups john

Cron Jobs

What do you mean by cron jobs, and how is it scheduled to run a script every day at 2 AM? 

A cron job is defined in a crontab file. Cron is a Linux utility to schedule tasks to run automatically at specified times. Example: To schedule a script ( /home/user/backup.sh ) to run daily at 2 AM: 0 2 * * * /home/user/backup.sh Where 0 means the minimum hour is 2, every day, every month, every day of the week.

How would you prevent cron job emails from being sent every time the job runs? 

By default, cron sends an email with the output of the job. You can prevent this by redirecting the output to /dev/null. Example: To run a script daily at 2 AM and discard its output: 0 2 * * * /home/user/backup.sh > /dev/null 2>&1   

System Performance Monitoring

How can you monitor system performance in Linux? Name some tools with their uses. 

Some of the tools to monitor the performance are: Top: Live view of system processes and usage of resource htop: More user-friendly when compared to the top with an interactive interface. vmstat: Displays information about processes, memory, paging, block IO, and                CPU usage. iostat: Showcases Central Processing Unit (CPU) and I/O statistics for devices and partitions. Example: You can use the top command ( top ) to identify processes consuming too much CPU or memory.

In Linux, how would you check the usage of disk space?

The df command checks disk space usage, and Du is responsible for checking the size of the directory/file. Example: To check overall disk space usage:  df -h The -h option depicts the size in a human-readable format like GB, MB, etc.

Package Management (Red Hat)

How do you install, update, or remove packages in Red Hat-based Linux distributions by yum command?

In Red Hat and CentOS systems, the yum package manager is used to install, update, or remove software. Install a package:  sudo yum install httpd This installs the Apache web server.  Update a package: sudo yum update httpd Remove a package:sudo yum remove httpd 

By which command will you check the installation of a package on a Red Hat system?

The yum list installed command is required to check whether the package is installed. Example: To check if httpd (Apache) is installed:  yum list installed httpd

Impact of successful SQLi, examples

Three common ways SQL injection attacks can impact web apps: - unauthorized access to sensitive data (user lists, personally identifiable information (PII), credit card numbers) - data modification/deletion - administrative access to the system (-> unauthorized access to specific areas of the system or malicious actions performance) examples as always speak louder than explanations! there are going to be two of them 1. Equifax data breach (2017) - 1st way Hackers exploited a SQL injection flaw in the company’s system, breaching the personal records of 143 million users, making it one of the largest cybercrimes related to identity theft. Damages: The total cost of the settlement included $300 million to a fund for victim compensation, $175 million to the states and territories in the agreement, and $100 million to the CFPB in fines. 2. Play Station Network Outage or PSN Hack (2011) - 2nd way Tthe result of an "external intrusion" on Sony's PlayStation Network and Qriocity services, in which personal details from approximately 77 million accounts were compromised and prevented users of PlayStation 3 and PlayStation Portable consoles from accessing the service. Damages: Sony stated that the outage costs were $171 million. more recent CVEs: CVE-2023-32530. SQL injection in security product dashboard using crafted certificate fields CVE-2020-12271. SQL injection in firewall product's admin interface or user portal, as exploited in the wild per CISA KEV. ! this vulnerability has critical severity with a score 10. Description: A SQL injection issue was found in SFOS 17.0, 17.1, 17.5, and 18.0 before 2020-04-25 on Sophos XG Firewall devices, as exploited in the wild in April 2020. This affected devices configured with either the administration (HTTPS) service or the User Portal exposed on the WAN zone. A successful attack may have caused remote code execution that exfiltrated usernames and hashed passwords for the local device admin(s), portal admins, and user accounts used for remote access (but not external Active Directory or LDAP passwords) CVE-2019-3792. An automation system written in Go contains an API that is vulnerable to SQL injection allowing the attacker to read privileged data. ! this vulnerability has medium severity with a score 6.8.
