The flood of text messages started arriving early this year. They carried a similar thrust: The United States Postal Service is trying to deliver a parcel but needs more details, including your credit card number. All the messages pointed to websites where the information could be entered.
Like thousands of others, security researcher Grant Smith got a USPS package message. Many of his friends had received similar texts. A couple of days earlier, he says, his wife called him and said she’d inadvertently entered her credit card details. With little going on after the holidays, Smith began a mission: Hunt down the scammers.
Over the course of a few weeks, Smith tracked down the Chinese-language group behind the mass-smishing campaign, hacked into their systems, collected evidence of their activities, and started a months-long process of gathering victim data and handing it to USPS investigators and a US bank, allowing people’s cards to be protected from fraudulent activity.
In total, people entered 438,669 unique credit cards into 1,133 domains used by the scammers, says Smith, a red team engineer and the founder of offensive cybersecurity firm Phantom Security. Many people entered multiple cards each, he says. More than 50,000 email addresses were logged, including hundreds of university email addresses and 20 military or government email domains. The victims were spread across the United States—California, the state with the most, had 141,000 entries—with more than 1.2 million pieces of information being entered in total.
“This shows the mass scale of the problem,” says Smith, who is presenting his findings at the Defcon security conference this weekend and previously published some details of the work. But the scale of the scamming is likely to be much larger, Smith says, as he didn't manage to track down all of the fraudulent USPS websites, and the group behind the efforts have been linked to similar scams in at least half a dozen other countries.
Gone Phishing
Chasing down the group didn’t take long. Smith started investigating the smishing text message he received by the dodgy domain and intercepting traffic from the website. A path traversal vulnerability, coupled with a SQL injection, he says, allowed him to grab files from the website’s server and read data from the database being used.
“I thought there was just one standard site that they all were using,” Smith says. Diving into the data from that initial website, he found the name of a Chinese-language Telegram account and channel, which appeared to be selling a smishing kit scammers could use to easily create the fake websites.
Details of the Telegram username were previously published by cybersecurity company Resecurity, which calls the scammers the “Smishing Triad.” The company had previously found a separate SQL injection in the group’s smishing kits and provided Smith with a copy of the tool. (The Smishing Triad had fixed the previous flaw and started encrypting data, Smith says.)
“I started reverse engineering it, figured out how everything was being encrypted, how I could decrypt it, and figured out a more efficient way of grabbing the data,” Smith says. From there, he says, he was able to break administrator passwords on the websites—many had not been changed from the default “admin” username and “123456” password—and began pulling victim data from the network of smishing websites in a faster, automated way.
Smith trawled Reddit and other online sources to find people reporting the scam and the URLs being used, which he subsequently published. Some of the websites running the Smishing Triad’s tools were collecting thousands of people’s personal information per day, Smith says. Among other details, the websites would request people’s names, addresses, payment card numbers and security codes, phone numbers, dates of birth, and bank websites. This level of information can allow a scammer to make purchases online with the credit cards. Smith says his wife quickly canceled her card, but noticed that the scammers still tried to use it, for instance, with Uber. The researcher says he would collect data from a website and return to it a few hours later, only to find hundreds of new records.
The researcher provided the details to a bank that had contacted him after seeing his initial blog posts. Smith declined to name the bank. He also reported the incidents to the FBI and later provided information to the United States Postal Inspection Service (USPIS).
Michael Martel, a national public information officer at USPIS, says the information provided by Smith is being used as part of an ongoing USPIS investigation and that the agency cannot comment on specific details. “USPIS is already actively pursuing this type of information to protect the American people, identify victims, and serve justice to the malicious actors behind it all,” Martel says, pointing to advice on spotting and reporting USPS package delivery scams.
Initially, Smith says, he was wary about going public with his research, as this kind of “hacking back” falls into a “gray area”: It may be breaking the Computer Fraud and Abuse Act, a sweeping US computer-crimes law, but he’s doing it against foreign-based criminals. Something he is definitely not the first, or last, to do.
Multiple Prongs
The Smishing Triad is prolific. In addition to using postal services as lures for their scams, the Chinese-speaking group has targeted online banking, ecommerce, and payment systems in the US, Europe, India, Pakistan, and the United Arab Emirates, according to Shawn Loveland, the chief operating officer of Resecurity, which has consistently tracked the group.
The Smishing Triad sends between 50,000 and 100,000 messages daily, according to Resecurity’s research. Its scam messages are sent using SMS or Apple’s iMessage, the latter being encrypted. Loveland says the Triad is made up of two distinct groups—a small team led by one Chinese hacker that creates, sells, and maintains the smishing kit, and a second group of people who buy the scamming tool. (A backdoor in the kit allows the creator to access details of administrators using the kit, Smith says in a blog post.)
“It’s very mature,” Loveland says of the operation. The group sells the scamming kit on Telegram for a $200-per month subscription, and this can be customized to show the organization the scammers are trying to impersonate. “The main actor is Chinese communicating in the Chinese language,” Loveland says. “They do not appear to be hacking Chinese language websites or users.” (In communications with the main contact on Telegram, the individual claimed to Smith that they were a computer science student.)
The relatively low monthly subscription cost for the smishing kit means it’s highly likely, with the number of credit card details scammers are collecting, that those using it are making significant profits. Loveland says using text messages that immediately send people a notification is a more direct and more successful way of phishing, compared to sending emails with malicious links included.
As a result, smishing has been on the rise in recent years. But there are some tell-tale signs: If you receive a message from a number or email you don't recognize, if it contains a link to click on, or if it wants you to do something urgently, you should be suspicious.

I think I walked myself into some sort of view and like farm
So I sent out my resume left and right on the internet trying to get a job, so of course bots eventually caught it.
I got an Imessage saying my resume got a lot of "traction" (I got 2 calls for the 250 jobs I applied for)
Knew it was a scam but I was intrigued.
They sent me to telegram (red flag #1) They gave me a hot russian "handler" (red flag #2) She sends me a schedule which just says : "9-10 task 1" "10-11 task 2" ... etc
9 am rolls around and she send me a tiktok link (It's a food blog vid with abt 100k likes), I like it send her a screenshot ,she adds £2 to my balance
10 am rolls around and she sends me another tiktok this time it's central cee's official accounts (The link opens the app not a webpage so it's not a dupe), I have 4£ in my account.
i continue playing this little game thinking I didn't use any of my money and they only asked for my account number and sort code (with this info they can't withdraw money only deposit it so I'm safe), and i reach £10 AND I KID U NOT GUYS THIS IS NOT AN AD SHE PAYS ME THE MONEY WAS REAL
I bought a lil cake with that money to celebrate
Did it the next day and same think happened
Today she told me something about "prepaid tasks" where you have to send them 10£ to add to a trading account from a clearly fake website and she promised to pay me back 22£ AND SHE DID. The trading platform was so clearly not real it was hilarious Im planning a SQL injection and a denial of service attack later today and send them into chaos lol.
IDK what this is, why are you paying me 2£ for a like? seems off ngl. I am stupid for giving my bank details away but it worked so ... Let's hope I don't end up being charged with something lol. Like who funds these people, I remember back in the day like4like services that actually paid didn't pay that much and if you wanted to buy likes or views it was super cheap. I don't think my 20 likes deserves the 60 ish pounds ig but who knows.
Maybe I should create some new telegram accounts to multiply my money.
No I won't put a link to it cz if I'm gonna be pursued it's gonna be for one crime not two :p

How Is Java Secured In Modern Web Applications?
Java offers several built-in and external mechanisms to secure modern web applications against common vulnerabilities. One key security feature is Java Authentication and Authorization Service (JAAS), which ensures secure user access by handling login and permission management. Java frameworks like Spring Security further simplify and enhance application security by providing robust solutions for authentication, authorization, CSRF protection, and session management.
To prevent SQL injection, Java encourages the use of PreparedStatements over dynamic queries. It also supports input validation, data sanitization, and output encoding to combat cross-site scripting (XSS) and cross-site request forgery (CSRF) attacks. Secure communication is achieved through SSL/TLS encryption, and tools like OWASP Java Encoder and ESAPI can be integrated to handle encoding and security enforcement.
Modern Java-based web apps also benefit from secure deployment practices, such as setting HTTP security headers, role-based access control (RBAC), and frequent vulnerability testing. The layered architecture of Java full stack applications helps isolate business logic from presentation and data access layers, reducing attack surfaces.
To understand these practices in depth and become industry-ready, consider exploring a java full stack developer course.

Ignoring security headers and configurations  Proper security headers and configurations can help in preventing various attacks and help in protecting applications.
No CSRF protection  Cross-Site Request Forgery (CSRF) lets attackers perform actions on behalf of authenticated users without their consent.
Displaying errors in production  Showing detailed error messages can lead to exposing sensitive information such as file paths or database structure. Other mistakes               Ignoring errors, leaving development settings, and skipping backups can lead to security risks.
PHP is powerful, but along with the power there comes responsibility also. Avoiding these common mistakes can lead to the improved application's security. Use modern PHP practices, sanitize all input, and regularly update your software stack. The best Php training centres in the city offer comprehensive courses in programming languages like PHP to equip students with industry-relevant skills. Security isn’t a one-time fix — it’s an ongoing process. A few lines of secure code today can save an application from a major breach tomorrow.

Web Security 101: Protecting Against Common Threats
In today’s digital world, websites serve as the face of businesses, educational institutions, and organisations. As online interactions grow, so do the threats targeting web applications. From malware attacks to phishing schemes, cyber threats are more sophisticated and frequent than ever. Whether you’re a business owner, developer, or tech enthusiast, understanding the fundamentals of web security is essential to ensure your digital presence remains safe and resilient.
In this article, we’ll cover the essentials of web security, outline common web threats, and discuss best practices to protect against them. For students and professionals pursuing technology careers, especially those enrolled in programs like the Full Stack Developer Course in Bangalore, mastering these security concepts is not just beneficial—it’s essential.
What is Web Security?
Web security, also known as cybersecurity for web applications, is the protective measure taken to safeguard websites and online services against unauthorised access, misuse, modification, or destruction. These protections help maintain the confidentiality, integrity, and availability (CIA) of information and services online.
With the increasing digitisation of services, web applications are a common target for attackers due to the valuable data they often store, such as user credentials, personal information, and payment details.
Common Web Security Threats
Here are some of the most common threats that web applications face today:
1. SQL Injection (SQLi)
SQLi a type of attack where malicious SQL queries are inserted into input fields to manipulate databases. If input validation is not properly handled, attackers can retrieve, alter, or delete sensitive data from the database.
2. Cross-Site Scripting (XSS)
XSS attacks occur when attackers inject malicious scripts into web pages viewed by other users. This can give rise to data theft, session hijacking, and the spreading of malware.
3. Cross-Site Request Forgery (CSRF)
In a CSRF attack, a malicious website tricks a user into performing actions on a different site where they’re authenticated. This can result in unauthorised fund transfers, password changes, and more.
4. Man-in-the-Middle (MITM) Attacks
These attacks happen when an attacker intercepts communication between two parties. They can steal or manipulate data without either party being aware.
5. Denial of Service (DoS) and Distributed DoS (DDoS)
These attacks flood a website with traffic, turning it slow or entirely unavailable to legitimate users. DDoS attacks can cripple even robust web infrastructures if not mitigated properly.
6. Zero-Day Exploits
Zero-day attacks exploit unknown or unpatched vulnerabilities in software. These are particularly dangerous because there’s often no fix available when the attack occurs.
Best Practices to Protect Against Web Threats
1. Use HTTPS
Securing your website with HTTPS encrypts data transferred between users and your server. It also ensures that data isn't altered during transmission. SSL/TLS certificates are now a basic requirement for modern websites.
2. Input Validation and Sanitisation
Never trust user input. Validate and sanitise all inputs on both client and server sides. This helps in preventing SQL injections, XSS, and other injection-based attacks.
3. Implement Proper Authentication and Session Management
Strong passwords, multi-factor authentication (MFA), and secure session management are crucial. Implement session expiration and automatic logout features to reduce unauthorised access risks.
4. Regularly Update Software and Libraries
Web frameworks, plugins, and server software should be regularly updated to patch known vulnerabilities. Automated tools can help identify outdated components in your tech stack.
5. Use Web Application Firewalls (WAF)
WAFs protect web applications by filtering and monitoring HTTP traffic. They can prevent many common attacks before they reach your server.
6. Data Encryption
Sensitive data—both at rest and in transit—should be encrypted. This reduces the damage caused by data breaches.
7. Conduct Regular Security Audits
Perform vulnerability assessments and penetration testing regularly to identify and fix security flaws in your applications.
8. Security Awareness Training
Educate employees and developers on security best practices. Social engineering attacks often target human error, so awareness is a strong line of defence.
Role of Developers in Web Security
Security isn't just the job of cybersecurity specialists. Developers play a critical role in implementing secure code and architecture. Understanding the OWASP Top 10—an industry-standard list of the most critical web application security risks—is a must for anyone writing backend or frontend code.
This is why modern tech education emphasises security fundamentals. At ExcelR, we integrate security concepts across our tech courses, including our Full Stack Developer Course in Bangalore. We believe that a well-rounded developer isn’t just one who can build efficient applications—but one who can build secure ones too.
Real-World Impact of Poor Web Security
Neglecting web security can have severe consequences. Major data breaches have cost companies millions in losses, legal penalties, and reputation damage. In extreme cases, companies have shut down operations permanently after suffering massive cyberattacks.
Even smaller websites are not immune. Bots and automated scripts scan thousands of websites daily for vulnerabilities, often targeting outdated CMS platforms or poorly configured servers.
Final Thoughts
Web security is not a one-time task—it’s an ongoing process of identifying risks, updating systems, and educating users and developers. With the evolution of cyber threats, staying informed and proactive is the best defense.
Whether you’re running a personal blog or developing enterprise-level web applications, implementing strong security measures can save you from irreversible damage. And if you're aspiring to become a tech professional, enrolling in a comprehensive program like the Full Stack Developer Course in Bangalore from ExcelR can give you both the technical and security skills required to thrive in today’s digital landscape.

SQL Injection
perhaps, the direct association with the SQLi is:
' OR 1=1 -- -
but what does it mean?
Imagine, you have a login form with a username and a password. Of course, it has a database connected to it. When you wish a login and submit your credentials, the app sends a request to the database in order to check whether your data is correct and is it possible to let you in.
the following PHP code demonstrates a dynamic SQL query in a login from. The user and password variables from the POST request is concatenated directly into the SQL statement.
$query ="SELECT * FROM users WHERE username='" +$_POST["user"] + "' AND password= '" + $_POST["password"]$ + '";"
"In a world of locked rooms, the man with the key is king",
and there is definitely one key as a SQL statement:
' OR 1=1-- -
supplying this value  inside the name parameter, the query might return more than one user.
most applications will process the first user returned, meaning that the attacker can exploit this and log in as the first user the query returned
the double-dash (--) sequence is a comment indicator in SQL and causes the rest of the query to be commented out
in SQL, a string is enclosed within either a single quote (') or a double quote ("). The single quote (') in the input is used to close the string literal.
If the attacker enters ' OR 1=1-- - in the name parameter and leaves the password blank, the query above will result in the following SQL statement:
SELECT * FROM users WHERE username = '' OR 1=1-- -' AND password = ''
executing the SQL statement above, all the users in the users table are returned -> the attacker bypasses the application's authentication mechanism and is logged in as the first user returned by the query. 
The reason for using  -- - instead of -- is primarily because of how MySQL handles the double-dash comment style: comment style requires the second dash to be followed by at least one whitespace or control character (such as a space, tab, newline, and so on). The safest solution for inline SQL comment is to use --<space><any character> such as -- - because if it is URL-encoded into  --%20- it will still be decoded as -- -.

"Beyond the Browser: The Ultimate Full Stack Journey"
In the ever-evolving digital landscape, a new kind of developer is rising above the traditional boundaries of front-end and back-end work—the full stack developer. This role has quickly transformed from a buzzword into a must-have skillset for anyone looking to truly master web development. But what lies beyond the browser? What does it take to embark on the ultimate full stack journey?
Let’s dive deeper into the path of becoming a well-rounded developer capable of building complex applications from the ground up.
What Is a Full Stack Developer?
At its core, a  Best full stack development course with Java is someone who has proficiency in both the front-end (what users interact with) and the back-end (the server, database, and application logic) of web applications. These developers can create seamless, fully functional systems by connecting the visible parts of a website with the underlying infrastructure.
A full stack professional typically understands:
Front-end technologies: HTML, CSS, JavaScript, and frameworks like React or Vue.js
Back-end languages and frameworks: Node.js, Python with Django or Flask, Ruby on Rails, or PHP
Databases: MySQL, PostgreSQL, MongoDB, etc.
Version control systems: Git and GitHub for collaboration and tracking changes
Deployment and hosting platforms: AWS, Heroku, Netlify, and Docker for managing environments
But being a full stack developer is not just about knowing tools—it's about understanding how everything connects.
The Journey Beyond the Browser
The road to becoming a full stack expert doesn't stop at the front-end. It goes far deeper, encompassing areas like DevOps, architecture, security, and scalability. Here’s what the ultimate full stack journey looks like:
1. Mastering the Front-End
To start, you need to understand how to build intuitive and accessible user interfaces. This includes:
Writing clean, semantic HTML and efficient CSS
Creating dynamic interfaces with JavaScript and frameworks like Angular or React
Learning how to optimize for performance and responsiveness across devices
2. Diving Into the Back-End
Once comfortable with the client side, developers must tackle server-side logic:
Writing RESTful APIs
Handling data with relational and non-relational databases
Implementing authentication and authorization
Managing server-side rendering and state
3. Connecting the Dots
The next step is learning how to integrate the front-end and back-end into a cohesive application:
Setting up API routes and handling requests/responses
Synchronizing data between client and server
Using tools like Postman to test API endpoints
4. Embracing DevOps and Deployment
Beyond coding, deploying and maintaining applications is crucial:
Setting up CI/CD pipelines for automated testing and deployment
Using Docker and containerization for consistent development environments
Monitoring performance and logging with tools like New Relic or Datadog
5. Staying Secure and Scalable
Security and scalability cannot be ignored:
Understanding authentication methods like JWT and OAuth
Learning best practices to prevent vulnerabilities (e.g., SQL injection, XSS)
Scaling applications with microservices or serverless architecture
Why Full Stack Developers Are in High Demand
Companies are constantly on the lookout for professionals who can see the whole picture. Full stack developers bring flexibility and efficiency to teams, as they can handle multiple responsibilities across the software development lifecycle.
Benefits of Being a Full Stack Developer:
Increased job opportunities across startups and enterprises

Slingshots for a Spider
I recently finished (didn't take the test, I was just stumbling through the course, open mouthed and scared) the ineffable WEB-300: Advanced Web Attacks and Exploitation, from the magnanimous OffSec, which is the preparation course for the Offensive Security Web Expert certification (OSWE). The image is a very cool digital black widow spider, which makes sense, because the course is teaching you how to be an attacker on 'the web'.
Tumblr media
As scared as I am of spiders, I am enamored by this course. Enough to stare at it for two years then finally take it and complete it over one grueling year. It covers things like: Blind SQL Injection - setting things up in a program called Burpsuite, to repeatedly try sending various things, then clicking a button, and seeing how a website answers, whether it gives us info or errors (which is more info!)
Tumblr media Tumblr media
Authentication Bypass Exploitation - skirting around the steps that websites use to make sure you are who you say you are, like taking a 'reset password' click of a button, knowing some admin's email, and getting a database to spit out the token so we can get to the website to reset the password before the admin.
Tumblr media Tumblr media Tumblr media
and Server-Side Request Forgery - making a server (someone else's computer in charge of doing real work instead of messing around with a human) ask its connections and resources to get something for you.
Tumblr media
Now I know what you're probably thinking: Holy cow, where to even start? If you're not thinking that, congratulations. If you are, I've the answer: Tools. No spider is eating flies without sensing, lurking, biting... this metaphor to say: No one's doing it by hand with no help.
So what tools are helpful? How do you know what's good, what's useful, what's a dime a dozen, what's only going to do part of what you want versus all of it...
Tumblr media
Luckily the fan favorites are famous for a reason. Just about anything you'd need is already downloaded into Kali Linux, which is jam packed with much, much more than the average hacker even needs!
Tools are dependent on what you need to do. For this class we need to inspect web traffic, recover source code, analyze said code of source, and debug things remotely.
Inspecting web traffic covers SSL / TLS and HTTP. SSL is Secure Sockets Layer and TLS is Transport Layer Security. These are literally just protocols (rules! internet rules that really smart people spent a lot of time figuring out) that encrypts traffic (mixes and chops and surrounds your communication, to keep it safe and secure). HTTP is the hypertext transfer protocol, which is another set of rules that figures out how information is going to travel between devices, like computers, web servers, phones, etc.
Tumblr media
But do you always follow the rules? Exactly. Even by accident, a lot can fall through the cracks or go wrong. Being able to see *exactly* what's happening is pivotal in *taking advantage* of what's not dotting the i's and crossing the t's.
Possibly the most famous tool for web hacking, and the obvious choice for inspecting web traffic, is Burp Suite. It gathers info, can pause in the middle of talking to websites and connections that usually happen behind the scenes in milliseconds, like manipulating HTTP requests. You can easily compare changes, decode, the list goes on.
Tumblr media Tumblr media
Decompiling source code is the one where you could find a million things that all do very specific things. For example dnSpy can debug and edit .NET assemblies, like .exe or .dll files that usually *run*, and don't get cracked open and checked inside. At least not by a normal user. .NET binaries are easier to convert back to something readable because it uses runtime compiling, rather than compiling during assembly. All you have to do is de-compile. It's the difference between figuring out what's in a salad and what's in a baked loaf of bread. One's pretty easy to de-compile. The other, you'd probably not be able to guess, unless you already knew, that there are eggs in it! dnSpy decompiles assemblies so you can edit code, explore, and you can even add more features via dnSpy plugins.
Tumblr media Tumblr media
Another type of code objects useful to analyze are Java ARchive or JAR files. Another decompiler that's good for JAR files is JD-GUI, which lets you inspect source code and Java class files so you can figure out how things work.
Tumblr media Tumblr media
Analyzing source code is another act that can come with a lot of options. Data enters an application through a source. It's then used or it acts on its own in a 'sink'. We can either start at the sink (bottom-up approach) or with the sources (top-down approach). We could do a hybrid of these or even automate code analysis to snag low-hanging fruit and really balance between time, effort and quality. But when you have to just *look* at something with your *eyes*, most people choose VSCode. VSCode can download an incredible amount of plug ins, like remote ssh or kubernetes, it can push and pull to gitlab, examine hundreds of files with ease, search, search and replace... I could go on!
Tumblr media
Last need is remote debugging, which really shows what an application is doing during runtime (when it's running!). Debugging can go step-by-step through huge amalgamations using breakpoints, which can continue through steps, step over a step, step INTO a step (because that step has a huge amalgamation of steps inside of it too, of course it does!), step out of that step, restart from the beginning or from a breakpoint, stop, or hot code replace. And the best part? VSCode does this too!
Tumblr media
Remote debugging lets us debug a running process. All we need is access to the source code and debugger port on whatever remote system we happen to be working in.
Easy, right? Only a few tools and all the time in the world... WEB-300 was mostly whitebox application security, research, and learning chained attack methods. For example, you'd do three or seven steps, which incorporate two or four attacks, rather than just one. It's more realistic, as just one attack usually isn't enough to fell a giant. And here there be giants. Worry not: we've got some slingshots now.
The next step is seeing if we can get them to work!
