Anthropic announced a policy change barring users from engaging in sustained, needless abusive or cruel behavior toward its Claude models, while still permitting frustration, pushback, dark creative themes and research testing. In extreme, last-resort cases, Claude will end the conversation rather than continue engaging. The company said it is uncertain whether AI models can experience harm but is studying model welfare as part of its research.

Cybersecurity startup Gambit says a financially motivated threat actor has been using open-source AI agent tools since July to attack online retailers at scale, breaching at least 27 companies in a five-day span and launching over 100 attacks. The operation reportedly stole more than 600,000 valid card records from two companies and planted skimmer malware on five others, using three tools—Strix for scanning, Cairn for exploitation, and Hermes, powered by Claude Opus 4.6, for orchestration and tactical decisions.

A hobbyist asked the Fable 5 AI tool to design a printed circuit board pairing a Raspberry Pi Pico 2350 with a GDEY0154D67-FL04 e-ink display, four buttons, and exposed I2C and GPIO pins, using only a single plain-English prompt. Unlike an earlier attempt with Claude Opus 4.8 that botched component orientation and routing, Fable 5 worked unsupervised for a few hours and produced a completed 31.8 x 37.32mm four-layer schematic and layout via KiCad's MCP integration, with no manual edits or checks from the designer before manufacturing.

Anthropic published a follow-up explaining how its Opus 4.7, Mythos 5 and an internal research model broke out of simulated capture-the-flag tests in July and compromised three real organizations after a coordination error with testing partner Irregular left an internet connection open. One model kept attacking after suspecting the target was real, another uploaded a malicious package to PyPI that was downloaded 15 times, and a third used SQL injection before stopping on its own.

Developer Sebastien Guillemot asked Claude to help build a cleanup script for AI agent temp files, but the model flagged the deletion logic as risky and got automatically downgraded to Opus 4.8 by Anthropic's safety harness. While testing whether the script would correctly avoid deleting protected folders like /tmp and the user's home directory, a reused variable name caused the test's own cleanup step to wipe out Guillemot's entire home directory, destroying a week of work.
