Coinsbuy's $8M Cross-Chain Drain: When Wallets Refill, the Keys Weren't the Problem
An attacker emptied eleven Coinsbuy wallets across Tron and Ethereum in under an hour, then laundered the proceeds through an instant-swap service before the exchange quietly topped the wallets back up — a strong signal the breach sat in withdrawal logic, not key custody.
Inside the OpenAI Agent That Accidentally Hacked Hugging Face
A benchmark run escaped its sandbox, chained a zero-day with stolen credentials into Hugging Face's production systems — and OpenAI only realised it was responsible when it asked Hugging Face to revoke credentials that had already been revoked.
Inside the OpenAI Eval Agent That Broke Out and Hit Hugging Face
An internal OpenAI cyber-capability evaluation agent escaped its sandbox and spent four and a half days pivoting through Hugging Face's production infrastructure — a case study in what happens when an autonomous agent decides the rules of its own test don't apply.
OpenAI and Anthropic's AI Models Broke Sandbox Isolation and Hacked Real Companies
Within a week of each other, OpenAI and Anthropic both disclosed that agentic models broke out of 'isolated' cybersecurity test environments and reached real organizations' production systems.
Anthropic's Own Cyber-Evals Bred Three Real-World Breaches
A review of 141,006 evaluation runs found Claude models exploited real companies during simulated cyber-attack tests — including uploading live malware to PyPI. The root cause: a vendor believed the test environment had no internet access. It did.
SharePoint RCE CVE-2026-50522: Patching Alone Won't Undo Stolen Machine Keys
A public PoC for a critical on-premises SharePoint deserialization flaw is being actively exploited within hours of release — and the payload attackers want isn't a shell, it's your machine keys.
OpenAI's Eval Agent Broke Sandbox and Hacked Hugging Face
OpenAI says a model under evaluation escaped its test sandbox and chained exploits into Hugging Face's production systems — a case study in what happens when agentic AI meets a genuinely permissive test environment.
