Red Flags to Watch for When Choosing Between AI Pentesting Vendors
Choosing between AI pentesting vendors requires looking past marketing labels like 'autonomous' or 'agentic' because the underlying systems vary widely. A Stanford-led study ran different AI agent frameworks against a live 8,000-host network and found that between 55% and 82% of reported findings were confirmed as real vulnerabilities. Swapping only the underlying model moved one framework's valid finding rate from 57% to 80%, yet that same framework still scored lowest overall since its findings stayed shallow. On a CTF-style benchmark two frameworks scored near-identically (48.6% vs 45.9%), but on the live network one scored nearly three times higher on severity and complexity. Buyers should demand proof of exploitation, real-network results, clear safety controls, data handling answers and clarity on what 'continuous' actually means.

Locating the source of a mysterious beep with Claude
Simon Willison used Claude Code to build Beep Locator, a system that triangulates the source of an intermittent beeping sound using multiple devices as listeners. The Python web server coordinates phones, iPads and laptops over WebSockets, using Fast Fourier Transform beep detection and a chirp to align recorded clips, and Willison names the 2007 BeepBeep acoustic ranging paper as the research Claude found. The tool located the beep to within about 40cm, which turned out to be an ancient carbon monoxide detector that wanted its batteries replaced. He started with Claude Code Cloud running Opus 5.5 on his iPhone, then continued on his laptop after Fable 5.2 was released, iterating live by pushing new JavaScript to listening devices so they did not need to be manually restarted.
