OS command injection is one of the most dangerous web vulnerabilities, often leading straight to full server compromise. Learn how it works, how attackers detect it, and how to prevent it properly.
A clear, practical guide to CSRF — how attackers make a victim's browser send unwanted authenticated requests, the conditions that make it possible, and the modern defences (SameSite cookies, anti-CSRF tokens) that stop it.

A practical, no-fluff roadmap for getting started in bug bounty hunting in 2026 — the skills to learn first, the tools that matter, how to pick your first target, and how to write a report that actually gets paid.
HTTP security headers are one of the cheapest, highest-impact defences you can add to a website. This guide explains each header that matters — CSP, HSTS, cookie flags, and more — what attack it stops, and the value to set.
Broken access control is the most common serious web vulnerability, and IDOR is its most reported form. Learn how these access-control flaws work, how testers find them, and how to fix them properly with server-side authorisation.

The OWASP Top 10 is the most referenced security standard for web applications. Here's a deep-dive into the 2025 update — what moved, what's new, and how to prioritise your remediation efforts.
Zero-day vulnerabilities are exploited before a patch exists. This post explains how organisations can build detection capabilities, containment procedures, and a response process that doesn't rely on waiting for a vendor fix.

APIs are the backbone of modern applications — and one of the most exploited attack surfaces. This guide walks through how to test an API the way an attacker would, covering reconnaissance, authentication, authorisation, business logic, and GraphQL.
Attackers are using YouTube videos, cracked software lures and hijacked channels to spread information-stealing malware. Here is how the scheme works and how to stay safe.
APT41 has been linked to a new malware loader called DodgeBox and a backdoor named MoonWalk. Here is how they work, the tricks they use, and why they are hard to catch.

A hacker and a penetration tester use many of the same techniques — the difference is authorisation and intent. A penetration tester has written permission from the organisation that owns the system, operates within an agreed scope, and delivers a report so the organisation can fix what was found. A malicious hacker has no permission, no scope, and no interest in helping anyone fix anything. The techniques overlap entirely; the legal and ethical context is what separates them.
Most compromises go undetected for months because they don't cause obvious disruption. Warning signs include: your server appearing in spam blocklists, Google Search Console flagging malware, sudden unexplained traffic spikes, new admin accounts you didn't create, unfamiliar files in your web root, or customers reporting phishing emails that look like they came from you. The uncomfortable truth is that without proper logging and monitoring in place, you often won't know until the damage is done. A vulnerability assessment can tell you whether your application has the kind of weaknesses that would make this likely.
Report it directly to the organisation through their official contact email or any published security or responsible disclosure policy. Don't exploit it, share it publicly, or sell it. If the organisation has a bug bounty programme on HackerOne, Bugcrowd, or Intigriti, submit it there — you may be eligible for a reward. If they don't respond within a reasonable time (30–90 days is the common standard), you can consider coordinated disclosure through a neutral third party. Never access data you weren't supposed to see, even to prove the vulnerability exists.
Yes — and small businesses are often easier targets precisely because attackers know security budgets are tight. Most attacks aren't targeted campaigns by sophisticated nation-state actors. They're automated scans looking for known vulnerabilities, credential stuffing attacks using leaked password lists, and opportunistic phishing. A small e-commerce site handling payment data is as attractive a target as a large one, sometimes more so because the defences are weaker. The good news: the most common vulnerabilities are also the most fixable, and you don't need an enterprise security budget to address them.
The short list: Burp Suite Pro for intercepting and manipulating web application traffic, nmap for network scanning and service detection, ffuf and gobuster for directory and parameter fuzzing, sqlmap for automated SQL injection verification, Metasploit for certain exploit frameworks, and a Kali Linux installation that brings most of these together. For API testing specifically, Postman or Insomnia for building requests, and Burp Suite for interception. The honest answer though is that the tool matters less than the methodology — a skilled tester with basic tools finds more than an unskilled tester with every tool available.
