  Supply-Chain Attacks on NPM/PyPI: How to Spot Malicious Packages The open-source ecosystem, while a cornerstone of modern software development, presents a double-edged sword. Package managers like NPM (Node Package Manager) for JavaScript and PyPI (Python Package Index) for Python offer unparalleled convenience and access to a vast array of libraries. However, this convenience also opens the door to a growing threat: supply-chain attacks. These attacks exploit the trust developers place in these ecosystems, injecting malicious code into seemingly legitimate packages. Imagine building a house, and unknowingly, one of your trusted suppliers delivers bricks laced with a slow-acting corrosive. That's what a supply-chain attack does to your software. The implications can range from data theft and system compromise to the deployment of backdoors, making it crucial for developers to understand how to spot and mitigate these threats. The Anatomy of a Supply-Chain Attack Supply-chain atta...

Cloud Misconfigurations Leading to Data Exfiltration: How IAM Mistakes, Metadata APIs, and Storage Buckets Still Expose Companies in 2025 Cloud security has never been more critical—or more misunderstood. As organisations rush to migrate workloads into AWS, GCP, and Azure, they often assume the cloud provider “handles the security.” But the shared responsibility model doesn’t work that way. Cloud platforms secure their infrastructure; you must ensure your own configurations . And that’s exactly where things still go wrong. In 2025, cloud breaches are rarely caused by exotic 0-days. Instead, attackers exploit simple misconfigurations, such as overly permissive IAM roles, exposed storage buckets, forgotten access keys, SSRF attacks targeting metadata endpoints, and accidental public resources. In fact, most real-world cloud breaches are rooted in mistakes that could have been avoided entirely. This article breaks down the most common cloud misconfigurations—across AWS, GCP, and Azure—t...

  Privilege Escalation in Web Applications: Vertical & Horizontal Strategies in 2025 How Logic Bugs, Broken Access Controls, and Role Confusion Still Break Modern Apps Privilege escalation has always been one of the most dangerous (and most profitable) vulnerability classes in web security. If you’ve spent any time bug hunting or pen testing, you already know how common it is to see a user “become admin” with just a small tweak in the request. It sounds dramatic, but it happens every day. And the reason is simple: Most web apps enforce authentication well, but authorization poorly. Developers know how to verify who you are (authentication). But keeping track of what you are allowed to do (authorization) is where things fall apart. In 2025, privilege escalation attacks still rank among the highest-severity bugs because they lead directly to: Account takeover Data leaks Access to internal administrative features Manipulation of other users Full system com...

  Bypassing WAFs and Rate Limits in 2025: Techniques That Still Work (Ethically) If you’ve been doing bug bounty or security testing for even a short while, you probably know this feeling: You discover a promising vulnerability… You try your payload… And then — blocked by WAF . Or worse — 429 Too Many Requests shuts you down mid-testing. Welcome to the world of Web Application Firewalls and Rate Limiting. Two layers are designed to protect applications, but often implemented imperfectly. Here’s the good news: Many WAF and rate limit bypass techniques still work in 2025 , even against modern cloud providers like Cloudflare, Imperva, Akamai, AWS WAF, and Fastly. This article explains how testers bypass them, why these methods work, and — most importantly — the ethical rules you must follow . 1. Understanding What WAFs Actually Do (And What They Don’t) A Web Application Firewall is not a bodyguard. It’s more like a security camera with built-in pattern recognition. I...
