How to Protect Your System from XSS Attacks

Cross-Site Scripting (XSS) is a web application vulnerability allowing third parties to execute scripts in a user's browser on behalf of the web application. How it works: An attacker sends a malicious link; the victim clicks it, visiting a legitimate site where the malicious script executes, sending the victim's data (e.g., session cookies) to the attacker. Consequences: XSS exploitation can lead to account compromise, account deletion, privilege escalation, and malware infection. Types of XSS: Reflected XSS: Requires repeated input for execution, often delivered directly to the victim (e.g., XSS in a search field). Stored XSS: The malicious script is stored on the server and executes on every visit without new payload submission (e.g., XSS in a comment thread). 𝐥𝐢𝐧𝐤𝐞𝐝𝐢𝐧-; https://lnkd.in/gKGa-Sgt 𝐈𝐧𝐬𝐭𝐚𝐠𝐫𝐚𝐦 :- https://lnkd.in/gGY5dVWg 𝐓𝐞𝐥𝐞𝐠𝐫𝐚𝐦 :- https://t.me/Cybertechap 𝐟𝐚𝐜𝐞𝐛𝐨𝐨𝐤:- https://lnkd.in/gJUfdp3e 𝐲𝐨𝐮𝐭𝐮𝐛𝐞 :- https://lnkd.in/gQ9tgDXu #termux #mobilelinux #ethicalhacking #cybersecurity #infosec #educationonly #linuxonandroid #techforbeginners #commandlineskills #thecyberbite #10kgift #ghostframework #androidsecurity #ethicalhacking #cybersecurity #infosec #educationonly #thecyberbite #GhostFramework #AndroidSecurity #MobilePentest #CyberSecurity #InfoSec #EducationOnly #EthicalHacking #RedTeam Tools #Android Testing #cybertechap2025

🚀 Day 18 of SutraByte45 Challenge 🚀 Today’s topic was Web Application Security 🌐🛡️ Web Application Security focuses on protecting websites and online applications from cyber threats and vulnerabilities. Since most modern businesses rely heavily on web apps, they are prime targets for attackers. Key areas covered today: 🔹 Common threats – SQL Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), Insecure Direct Object References (IDOR). 🔹 OWASP Top 10 – the industry standard list highlighting the most critical web application vulnerabilities. 🔹 Security practices – input validation, secure authentication, session management, encryption, and proper error handling. 🔹 Testing tools – Burp Suite, OWASP ZAP, Nikto, and automated scanners to identify vulnerabilities. 🔹 Defensive approach – applying secure coding practices, regular security testing, and patching to safeguard sensitive data and user trust. Web application security is a cornerstone of cyber security because a single vulnerability can expose critical data and damage organizational reputation. #SutraByte45 #Day18 #WebApplicationSecurity #OWASP #CyberSecurity #LearningChallenge

When Malware Becomes Manager Recently, the popular open-source framework Nx was compromised — attackers injected malicious code that could steal wallets and credentials. (The link is in comments) What makes it different? Instead of acting like “classic” malware, this code looked like tasks for developer tools and coding agents. In other words, we’re entering an era where viruses don’t just execute — they assign coding jobs to automated agents. Looks innovative and creative.. and quite dangerous. Is it a new type of malware?

🔒 Security Research Update 🔒 While exploring web application security, Shivam Chaudhary and I discovered a Reflected Cross-Site Scripting (XSS) vulnerability on the Candere By Kalyan Jewellers website. 💡 What we found: The vulnerable parameter was q in the search functionality. By injecting JavaScript payloads, we were able to demonstrate: JavaScript execution via alert box Forced redirection to external sites ⚠️ Why it matters: If left unpatched, such vulnerabilities could allow: Session hijacking Data theft Phishing & malicious redirects Brand reputation risks ✅ What we did: We followed responsible disclosure practices and immediately reported the issue to Candere’s Security / Support team for remediation. 🔐 Takeaway: Even a small input field, when unsanitized, can open doors to severe exploits. Proper input validation, output encoding, and CSP (Content Security Policy) are critical to securing web applications. 👨💻 Security is a shared responsibility. Glad to contribute towards making the web safer! #XSS #BugBounty #WebSecurity #ResponsibleDisclosure #CyberSecurity #Candere #EthicalHacking

#Return-Oriented Programming (ROP) Attack Real-World Implications: Advanced Persistent Threats (APTs): These techniques are often used in sophisticated attacks where the goal is to remain undetected for long periods while extracting valuable information. Malware: Some malware uses similar tactics to evade detection by security software, performing malicious actions only when certain conditions are met and reverting to benign behavior otherwise. Exploits: Exploits that manipulate program logic at different stages can be used to gain unauthorized access, escalate privileges, or execute arbitrary code.

All kinds of new cyber attacks are on the rise with the rise in popularity of new AI tooling, and they are becoming more sophisticated. There has never been a greater need to be informed of how to protect against these threats. https://lnkd.in/e85Srise

Ever wondered how a simple header could unlock the door to an entire admin system. I recently dove into an awesome writeup where the author brilliantly chained an authentication bypass with an XXE (XML External Entity) attack to outsmart a real-world web challenge. By leveraging the “X-Middleware-Subrequest: middleware” header, the attacker sidestepped login restrictions—waltzing straight into admin territory. But the real game-changer? Using a clever XXE payload to access sensitive files and grab the coveted flag. What really strikes me here is how easily overlooked middleware vulnerabilities can become the weakest link in our security chains. As someone fascinated by offensive and defensive strategies in cybersecurity, this is a wakeup call: even “insignificant” misconfigurations can open up devastating attack paths. For every security pro, developer, or tech leader out there: never underestimate the power of layered, detail-focused defenses. These lessons remind us to always challenge our assumptions and stay two steps ahead. 🔗 Full article by here → https://lnkd.in/gq9b3gVw #CyberSecurity #Infosec #WebSecurity #CTF #BugBounty #CTFWriteups #EthicalHacking #CyberAwareness #AppSec #RedTeam #Pentesting #SecurityRisk #ZeroDay #DataProtection #SecurityFirst

Application security isn't just a checkbox — it's a continuous process that starts with the first line of code. As cyber threats grow more sophisticated, developers need to take a proactive stance on securing applications. Gyan Chawdhary shares some essential practices every dev team should bake into their workflow: ✅ Validate all user input — protect your app from injection attacks like SQLi and XSS. 🔐 Strengthen authentication and tightly control access to sensitive data. 🧑💻 Follow secure coding standards and review code regularly to catch vulnerabilities early. 🔒 Encrypt sensitive data both in transit and at rest. 🧪 Test often — regular pen tests and vulnerability scans keep risks in check. Secure applications don’t happen by accident — they happen by design. Let’s build with security in mind from day one. 💡 Read the blog: https://lnkd.in/gAbpefy6 #ApplicationSecurity #AppSec #SecureCoding #DevSecOps #Cybersecurity #SoftwareDevelopment #CodeSmart
