GraphQL APIs offer flexibility but expose risks like access control flaws, DoS attacks, and injections. In my latest in-depth exploration, uncover schema introspection for recon, BOLA exploits with cURL examples and Burp workflows, SQL/NoSQL injections, and command injection like Chaos Mesh’s RCE issues. Test for DoS via complex queries (with caution—often out of scope). Tools such as GraphQL Voyager, InQL, and GraphQLMap streamline testing. Defenses include disabling introspection, granular auth, and query limits. Vital for pentesters in modern stacks.

Mastering XSS Categories: Precise Detection and PoC Crafting in Modern JS Apps
In my latest deep-dive, I explore the evolving landscape of XSS vulnerabilities in 2025, emphasizing precise categories like Reflected, Stored, DOM-based, and hybrids such as Reflected DOM-XSS and Stored DOM-XSS. Drawing from recent CVEs in Adobe Experience Manager and WordPress plugins, I outline source-sink tracing workflows using tools like Burp’s DOM Invader and browser devtools to detect flaws that server-side scanners miss. Key insights include tailoring PoCs to sinks, for example, using the onerror event handler with an img tag for innerHTML while avoiding non-executing script tags, and testing fragments, client storage, and postMessage channels in SPAs. Recommendations focus on sink-aware payloads, hybrid path coverage, and defenses like Trusted Types and context-appropriate encoding to build reproducible exploits and strong mitigations.
AI in Penetration Testing: Speeding Up Offense & Shaking Up Security
AI is already accelerating penetration testing. In a verified benchmark, an AI platform matched a veteran’s success rate in about half an hour while the human needed forty hours. The deep dive explains where that speed helps in practice, including triaging scan output, suggesting exploits, and drafting reports. It also covers what not to automate, including creative chaining and social engineering. You will get practical guardrails such as running private models, sanitizing inputs, and verifying every finding. I close with a realistic playbook for treating AI like a junior copilot while tracking attacker use of generative AI.
Mastering Network Pentesting in Zero-Trust Architectures: 2025 Strategies
In 2025, zero-trust architectures (ZTAs) are revolutionizing network defense, but they’re not impenetrable. My latest blog dives into advanced pentesting strategies, drawing from recent breaches like the ToolShell chain in Microsoft SharePoint (CVEs 2025-49704, -49706, -53770, -53771) and Ivanti exploits by UNC5221. Learn step-by-step methodologies: from asset mapping with BloodHound and Nmap, to authentication bypasses, segmentation probes using Scapy, and post-exploitation with Covenant. Key insights include avoiding policy drift, leveraging OWASP for microservices, and purple teaming for fixes. Backed by CISA, NIST, and real-world trends, this guide equips pentesters to emulate adversaries effectively. What’s your toughest ZTA challenge?
