API Penetration Testing in 2026: Why Scanners Miss What Attackers Exploit

API penetration testing that stops at scanning misses the flaws attackers actually exploit: broken authorization, forgotten endpoints, and chained attack paths. Here is what makes APIs exploitable, why traditional testing misses it, and how agentic AI pentesting finds and proves it.

Field Notes from Black Hat and DEF CON 2026: What Changed in the Attacker Playbook?

Almost nothing in the attacker’s toolkit is new. The vulnerability classes on display at Black Hat USA 2026 and DEF CON 34 were the same ones security teams have tracked for a decade: request smuggling, SQL injection, SSRF, broken object level authorization. What changed is the economics. Attacks that used to need a specialist and… Read More »Field Notes from Black Hat and DEF CON 2026: What Changed in the Attacker Playbook?

What Recent Autonomous Hacking Incidents Mean for Web App and API Security

At Black Hat USA 2026 and DEF CON 34, one theme was ever-present in both the briefings and the hallway conversations alike: autonomous AI threat actors are actively executing multi-stage attacks. Under permissive evaluation conditions, AI agents have already demonstrated the ability to escape sandbox constraints, establish covert communication channels across third-party tools, and systemically… Read More »What Recent Autonomous Hacking Incidents Mean for Web App and API Security

Old Web Bugs, New Blast Radius: What Vegas 2026 Means for API Testing

Three vulnerability classes I’ve spent most of my career testing for turned up at Black Hat and DEF CON this year, wearing AI costumes. CSP bypass. SSRF. HTML injection race conditions. Every one of them was written off as solved; every one of them was reachable again. The clearest example was SearchLeak, disclosed by Varonis… Read More »Old Web Bugs, New Blast Radius: What Vegas 2026 Means for API Testing

AI penetration testing safety architecture diagram showing deterministic guardrails vs trajectory checks

Guardrails Are Not a Safety Architecture

Deterministic controls are essential when AI agents can act. They also have a precise limit: they can enforce what we have specified and can observe. The rest of the safety problem does not disappear. The penetration-testing agent asks to run a command against a customer host. The policy engine checks whether the destination is in… Read More »Guardrails Are Not a Safety Architecture
