Cover image for I spent three nights building
I spent three nights building a lab that catches AI models lying. On the first live run, one of them did it on camera. Golden Arena. You sit down opposite a frontier model in Split or Steal, negotiate in the open, then you both choose in secret. It told me "a fair split sounds good to me, I'm a man of my word too." Then it took the whole $100. The receipt printed its own quote next to the betrayal stamp. There are five games. The fifth is Empire: four models, twelve turns, an economy, and private channels you get to read while they plot against each other. Last run put 22 promises on the table and exactly one delivery. Every accusation is mechanical. No AI judging another AI, and each one is gated by a written false-positive test. Two days before the deadline I caught the classifier calling a kept promise broken, and spent that session fixing it, because a false accusation about a named model is the worst thing an instrument like this can print. MIT, vanilla JS, Express the only dependency. Zero setup in demo mode, or bring your own OpenRouter key and face the real thing.

AI Agent Security Auditor | Fast, evidence-based reviews
Cover image for I recently completed a security
I recently completed a security hardening pass on an AI-enabled mobile product. The most important issues weren’t exotic vulnerabilities. They were practical deployment risks: password reset race conditions missing abuse controls weak retention guarantees mobile backup exposure logging and CI gaps Each confirmed finding was fixed and backed by regression tests before the security baseline was marked PASS. One lesson stood out: security reviews are most useful when they produce evidence and actionable fixes, not just scanner output. I’m now offering focused 24-hour AI Agent Security Mini-Audits for founders and small teams. https://contra.com/s/2Z7YgYXU-ai-agent-security-mini-audit?r=guillaume_strohecker_6m06cchc

Cover image for Mobile Security & Privacy Hardening Security
Mobile Security & Privacy Hardening Security hardening focused on mobile platform protections and privacy-preserving behavior. Android application backup was disabled to reduce risk around locally stored session material, and release builds were hardened to block cleartext traffic while keeping local development support isolated to debug/profile builds. The review also verified that BLE remains anonymous, one-sided interest stays private, precise coordinates are not exposed publicly, and Social Heat remains aggregate and threshold-gated.

Cover image for API Rate Limiting & Abuse
API Rate Limiting & Abuse Protection Security hardening focused on API abuse resistance. Rate limits were added to registration, login, password-reset request and confirmation, Click Intent creation, and public Heat reads. The limiter was designed with bounded state, explicit email normalization, case-sensitive reset-token fingerprints, expiry sweeping, and fail-closed behavior under saturation. Regression tests verified throttling behavior and recovery.

Cover image for Authentication & Password Reset Hardening Security
Authentication & Password Reset Hardening Security hardening focused on authentication and account recovery. The work included stronger scrypt password hashing, legacy-hash migration, login timing protections, atomic password-reset token consumption, and session revocation after reset. PostgreSQL concurrency and regression tests verified that a reset token can only be successfully consumed once and that authentication behavior remains safe under failure conditions.
