During my last FOR610 session, a student asked me if I had some statistics in mind about the compilers used to generate malicious PE files? A couple of months ago, I shared some stats about the trend in 64bits VS. 32bits malware[1]. Can we go a bit further? I (vibe-)coded a Python script based on the pefile library[2] to extract some info from the PE headers. Indeed, the PE file format contains a lot of metadata! They can be accessed using a lot of tools, like Detect It Easy:

If you’re running AI agents in production, Amazon Bedrock Guardrails protects the model boundary. But your agents also invoke tools, fetch external data, and communicate with other systems. That data flows outside the model boundary, where model-level guardrails can’t reach. You can extend guardrail coverage to those interactions using three validation checkpoints built with the […]

A fake login page. A fake security scan. A fake productivity app. Apparently, pretending to be useful is still one of the easier ways into a machine. The rest of the week gets stranger: botnets borrowing AI, command traffic hiding in public infrastructure, malicious tools waiting before showing their real behavior, exposed systems getting scanned, and exploit windows shrinking again. Different
