Hotmail service was founded by Sabeer Bhatia and Jack Smith, and was one of the first webmail services on the Internet along with Four11's RocketMail (later Yahoo! Mail). It was commercially launched on July 4, 1996, symbolizing "freedom" from ISP-based email and the ability to access a user's inbox from anywhere in the world. The name "Hotmail" was chosen out of many possibilities ending in "-mail" as it included the letters HTML, the markup language used to create web pages (to emphasize this, the original type casing was "HoTMaiL"). The limit for free storage was 2 MB. Hotmail was initially backed by venture capital firm Draper Fisher Jurvetson. By December 1997, it reported more than 8.5 million subscribers. Hotmail initially ran under Solaris for mail services and Apache on FreeBSD for web services, before being partly converted to Microsoft products, using Windows Services for UNIX in the migration path.

Hotmail was sold to Microsoft in December 1997 for a reported $400 million (~$705 million in 2023), and it joined the MSN group of services. The sale had been preceded by a major incident in 1997 where all email was lost for 25% of mailboxes. Hotmail quickly gained in popularity as it was localized for different markets around the globe, and became the world's largest webmail service with more than 30 million active members reported by February 1999.

Hotmail originally ran on a mixture of FreeBSD and Solaris operating systems. A project was started to move Hotmail to Windows 2000. In June 2001, Microsoft claimed this had been completed; a few days later they retracted the statement and admitted that the DNS functions of the Hotmail system were still reliant on FreeBSD. In 2002 Hotmail still ran its infrastructure on UNIX servers, with only the front-end converted to Windows 2000. Later development saw the service tied with Microsoft's web authentication scheme, Microsoft Passport (now Microsoft account), and integration with Microsoft's instant messaging and social networking programs, MSN Messenger and MSN Spaces (later Windows Live Messenger and Windows Live Spaces, respectively).

I’m sorry but I’m still losing my fucking MIND over elons incomprehensible Linux own the libs tweet like

Like it’s incredibly obvious he heard about a traceroute, and then googled “how to delete file in Linux” and then didn’t even read the results

Like… woke_mind_virus isn’t a fully qualified domain name, meaning it relies on a custom DNS resolution specific to his machine, or if utilizing a vpn, that specific vpn’s custom host file. Or that the American government would have a host entry for a woke mind virus, which if you’ve ever had to use a government website, is laughable. Also DNS is global for the most part, but honestly we can move on at this point.

So sure, we’ll say that the government has forced all public internet in America to resolve woke_mind_virus. Where does it resolve to? YOUR OWN COMPUTER, you silly billy! Obviously! This is *almost* comprehensible. Sure, we are all infected with the woke mind virus, why not. It must be destroyed within ourselves. Yeah man, whatever. Why not? So how do we destroy it?

Duh! Just delete it! How do we do that in our L337 uber hax0r terminal on our fresh kali live usb (because partitions are scary)? We’ll save that for last.

Because while deleting one file could make a website inoperable, it does not remove every trace of it! It first needs a configuration file in the web server, usually Apache or nginx. This is at LEAST one file, but cmon, if you’re gonna psychologically program the masses and keep it out of public view, you gotta encrypt that shit! So naturally, an SSL is in order! That’s easily 1-3 more files. woke_mind_virus can get a pass on not being fully qualified in this specific case because certs can theoretically be self signed and trusted on local networks, but he wouldn’t be able to tell you that. If you stood up a little one page html site on a web server on your own computer, and navigated to it on port 443 (https://) you would get an SSL error, even though it’s on your own machine. I feel like I’ve beaten this into the ground enough, but just understand it’s stupid.

What’s important to note here is that these BARE MINIMUM files are what routes the request from your machine to the destination site, even if it’s your own computer. If you delete the contents of the site (also called the docroot), the site still exists, and can receive and route requests to and from it, it’s just empty. You’ll probably get a 404 because there’s no actual content to serve. This woke mind princess is in another castle.

It’s also imprudent to delete these configuration files first, because that’s how you determine where the site content actually is! These files dictate what directory (folder for you windows losers) is called upon to actually serve you the content you see displayed when you open a webpage. So you need this information if you don’t want to destroy the entire file system and only want to remove the woke_mind_virus site. Cmon Elon, this is baby shit.

So of course, the strat with the most Efficiency and preserving the rest of the system (which seems to be the point of the tweet) is to find the docroot, delete the docroot, and then delete the web server config files. So how do we delete them?

And here we have it: rm -rf

The syntax is as follows:

rm -rf </path/to/file>

Even if you don’t know shit about Linux, you can probably see the problem here. It’s just so blatantly incorrect, it’s almost as if he’s never done it before.

For those that want to see a real world example, here is me creating a file called woke_mind_virus in my home directory and then trying to delete it the Elon Way:

Secure Your Laravel App: Fix Insufficient Transport Layer Security (TLS)

Introduction

Transport Layer Security (TLS) is vital for ensuring secure communication between clients and servers over the Internet. Insufficient TLS configurations can leave your Laravel web applications exposed to various cyber threats, like Man-in-the-Middle (MitM) attacks. In this blog post, we’ll explain the risks associated with insufficient TLS security in Laravel and provide a detailed guide on how to configure your Laravel application for optimal security.

Additionally, we’ll show you how to check and resolve potential TLS issues using our free Website Security Scanner tool.

What is Insufficient Transport Layer Security?

Insufficient Transport Layer Security occurs when a website fails to use strong encryption protocols like TLS 1.2 or higher, or when it doesn't properly configure SSL certificates. This exposes web applications to data interception, tampering, and attacks. A properly configured TLS ensures that all data transmitted between the server and client is encrypted and secure.

Common Issues in Laravel with Insufficient TLS Security

Some common causes of insufficient TLS in Laravel include:

Outdated SSL Certificates: Using deprecated SSL/TLS protocols (like SSL 3.0 or TLS 1.0) that are no longer considered secure.

Improper SSL/TLS Configuration: Misconfiguration of the web server or Laravel app that doesn’t force HTTPS or downgrade protection.

Weak Cipher Suites: Servers using weak ciphers, making it easier for attackers to break the encryption.

Lack of HTTP Strict Transport Security (HSTS): Without HSTS, an attacker can force the browser to use an insecure HTTP connection instead of HTTPS.

How to Fix Insufficient TLS in Laravel

Upgrade Your Laravel App’s TLS Protocol To enforce TLS 1.2 or higher, you'll need to configure your server to support these protocols. Here’s how you can configure your server to prioritize stronger encryption:

In Apache: Modify the ssl.conf file:

SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1

In Nginx: Edit your nginx.conf file:

ssl_protocols TLSv1.2 TLSv1.3;

These configurations will ensure that your server uses only secure versions of TLS.

2. Force HTTPS in Laravel Laravel provides an easy way to force HTTPS by modifying the .env file and the config/app.php file:

In .env file:

APP_URL=https://yourdomain.com

In config/app.php file:

'url' => env('APP_URL', 'https://yourdomain.com'),

This will ensure that all requests are redirected to HTTPS, preventing insecure HTTP access.

3. Enable HTTP Strict Transport Security (HSTS) HTTP Strict Transport Security is a web security policy mechanism that helps to protect websites against Man-in-the-Middle (MitM) attacks by forcing clients to communicate over HTTPS. Here's how to add HSTS headers to your Laravel app:

In Apache: Add the following line to your ssl.conf or .htaccess file:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

In Nginx: Add the following line to your nginx.conf file:

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

4. Use Strong Cipher Suites Weak cipher suites allow attackers to break the encryption. You can configure your server to use strong ciphers:

In Apache:

SSLCipherSuite HIGH:!aNULL:!MD5:!3DES

In Nginx:

ssl_ciphers 'ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256';

5. Use a Valid SSL/TLS Certificate Ensure that your website uses a valid SSL/TLS certificate from a trusted Certificate Authority (CA). You can get a free SSL certificate from Let's Encrypt.

How to Check TLS Configuration with Our Free Tool

Before and after implementing the changes, it’s essential to check the security status of your website. You can use our free Website Security Checker Tool to evaluate your website’s TLS configuration.

Package Management (Red Hat)

Conclusion

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?

NVIDIA AI Workflows Detect False Credit Card Transactions

A Novel AI Workflow from NVIDIA Identifies False Credit Card Transactions.

The process, which is powered by the NVIDIA AI platform on AWS, may reduce risk and save money for financial services companies.

By 2026, global credit card transaction fraud is predicted to cause $43 billion in damages.

Using rapid data processing and sophisticated algorithms, a new fraud detection NVIDIA AI workflows on Amazon Web Services (AWS) will assist fight this growing pandemic by enhancing AI’s capacity to identify and stop credit card transaction fraud.

In contrast to conventional techniques, the process, which was introduced this week at the Money20/20 fintech conference, helps financial institutions spot minute trends and irregularities in transaction data by analyzing user behavior. This increases accuracy and lowers false positives.

Users may use the NVIDIA AI Enterprise software platform and NVIDIA GPU instances to expedite the transition of their fraud detection operations from conventional computation to accelerated compute.

Companies that use complete machine learning tools and methods may see an estimated 40% increase in the accuracy of fraud detection, which will help them find and stop criminals more quickly and lessen damage.

As a result, top financial institutions like Capital One and American Express have started using AI to develop exclusive solutions that improve client safety and reduce fraud.

With the help of NVIDIA AI, the new NVIDIA workflow speeds up data processing, model training, and inference while showcasing how these elements can be combined into a single, user-friendly software package.

The procedure, which is now geared for credit card transaction fraud, might be modified for use cases including money laundering, account takeover, and new account fraud.

Enhanced Processing for Fraud Identification

It is more crucial than ever for businesses in all sectors, including financial services, to use computational capacity that is economical and energy-efficient as AI models grow in complexity, size, and variety.

Conventional data science pipelines don’t have the compute acceleration needed to process the enormous amounts of data needed to combat fraud in the face of the industry’s continually increasing losses. Payment organizations may be able to save money and time on data processing by using NVIDIA RAPIDS Accelerator for Apache Spark.

Financial institutions are using NVIDIA’s AI and accelerated computing solutions to effectively handle massive datasets and provide real-time AI performance with intricate AI models.

The industry standard for detecting fraud has long been the use of gradient-boosted decision trees, a kind of machine learning technique that uses libraries like XGBoost.

Utilizing the NVIDIA RAPIDS suite of AI libraries, the new NVIDIA AI workflows for fraud detection improves XGBoost by adding graph neural network (GNN) embeddings as extra features to assist lower false positives.

In order to generate and train a model that can be coordinated with the NVIDIA Triton Inference Server and the NVIDIA Morpheus Runtime Core library for real-time inferencing, the GNN embeddings are fed into XGBoost.

All incoming data is safely inspected and categorized by the NVIDIA Morpheus framework, which also flags potentially suspicious behavior and tags it with patterns. The NVIDIA Triton Inference Server optimizes throughput, latency, and utilization while making it easier to infer all kinds of AI model deployments in production.

NVIDIA AI Enterprise provides Morpheus, RAPIDS, and Triton Inference Server.

Leading Financial Services Companies Use AI

AI is assisting in the fight against the growing trend of online or mobile fraud losses, which are being reported by several major financial institutions in North America.

American Express started using artificial intelligence (AI) to combat fraud in 2010. The company uses fraud detection algorithms to track all client transactions worldwide in real time, producing fraud determinations in a matter of milliseconds. American Express improved model accuracy by using a variety of sophisticated algorithms, one of which used the NVIDIA AI platform, therefore strengthening the organization’s capacity to combat fraud.

Large language models and generative AI are used by the European digital bank Bunq to assist in the detection of fraud and money laundering. With NVIDIA accelerated processing, its AI-powered transaction-monitoring system was able to train models at over 100 times quicker rates.

In March, BNY said that it was the first big bank to implement an NVIDIA DGX SuperPOD with DGX H100 systems. This would aid in the development of solutions that enable use cases such as fraud detection.

In order to improve their financial services apps and help protect their clients’ funds, identities, and digital accounts, systems integrators, software suppliers, and cloud service providers may now include the new NVIDIA AI workflows for fraud detection. NVIDIA Technical Blog post on enhancing fraud detection with GNNs and investigate the NVIDIA AI workflows for fraud detection.

Progress so far of mobile server (dev log)

So I was successful in turning my old phone into apache web server. The phone had some hardware issue that it always clicked on the screen randomly so I had to maneuverer my way installing Linux and apache into the phone. I had to set up proxies as well to connect to it with the open internet. So far it is working well. Sometimes I have to reroute the connections since it is running over mobile data? I am thinking of getting a dynamic DNS. But I have never tried dynamic DNS before so I am not ready to explore that yet. Plus, I don't know if I would get a static IP from it or a straight away domain name? I mean both are okay, but both have pros and cons of the usage.

Like if I get a static IP , I can run virtual hosts in apache and run multiple websites pointing A record of the domain to the same website.

And lets say if I get a subdomain from the dynamic DNS, I can point CNAME record of the domain to subdomain? But will virtual hosts work with it? I don't know. I suppose it should but it could not work also. Hmm.. lets see, I think I have done this before, apache virtual hosts works with CNAME.

But there is another issue that one of the website runs behind a SOCKS5 proxy, How will I accommodate that? The issue is that, since its Ubuntu running over VM over lineage OS in phone, I can't get low number ports such 80 or 443 so I have to somehow use Dynamic DNS and SOCKS5 proxy to redirect traffic at higher port number.

I mean, I still have oracle VPS running so I may not need virtual hosts in mobile server. So maybe I will venture this when I need it.

I am just wondering whether I should run Docker to run my game server then redirect the traffic with apache virtual hosts, reverse proxy with SOCKS5 proxy? I don't even know if it work. Theoretically it should work.
