Claude Stress Neurons & Cybersecurity /ai_pentesting /neurosec /enterprise CLAUDE STRESS NEURONS How emergent “stress circuits” inside Claude‑style models could rewire blue‑team workflows, red‑team tradecraft, and the entire threat model of big‑corp cybersecurity. MODE: deep‑dive AUTHOR: gk // 0xsec STACK: LLM x Neurosec x AppSec Claude doesn’t literally grow new neurons when you put it under pressure, but the way its internal features light up under high‑stakes prompts feels dangerously close to a digital fight‑or‑flight response. Inside those billions of parameters, you get clusters of activations that only show up when the model thinks the stakes are high: security reviews, red‑team drills, or shutdown‑style questions that smell like an interrog...

Claude Code Hooks: The Deterministic Security Layer Your AI Agent Needs > APPSEC_ENGINEERING // CLAUDE_CODE // FIELD_REPORT Claude Code Hooks: The Deterministic Security Layer Your AI Agent Needs CLAUDE.md rules are suggestions. Hooks are enforced gates. exit 2 = blocked. No negotiation. If you're letting an AI agent write code without guardrails, here's how you fix that. // March 2026 • 12 min read • security-first perspective Why This Matters (Or: How Your AI Agent Became an Insider Threat) Since the corporate suits decided to go all in with AI (and fire half of the IT population), the market has changed dramatically, let's cut through the noise. The suits in the boardroom are excited about AI agents. "Autonomous productivity!" they say. "Digital workforce!" they cheer. Meanwhile, those of us who actually hack things for a living are watching these agents get deployed with shell access, API keys, and service-l...

External Service Interaction & Out-of-Band Resource Loads — Updated 2026 External Service Interaction & Out-of-Band Resource Loads Host Header Exploitation // SSRF Primitives // Infrastructure Pivoting SSRF Host Header Injection CWE-918 OWASP A10:2021 Cache Poisoning Updated 2026 In the recent past we encountered two relatively new types of attacks: External Service Interaction (ESI) and Out-of-Band Resource Loads (OfBRL). An ESI [1] occurs only when a web application allows interaction with an arbitrary external service. OfBRL [6] arises when it is possible to induce an application to fetch content from an arbitrary external location, and incorporate that content into the application's own response(s). Taxonomy Note (2026): Both ESI and OfBRL are now classified under OWASP A10:2021 — SSRF and map to CWE-918 (Server-Side Request Forgery). ESI also maps to CWE-441 (Unintentional Pro...
