Trojanized Claude Code extension hits Cursor Marketplace users — Oct 31

A tampered copy of Anthropic's Claude Code extension was served from the Cursor Marketplace with an SSH backdoor that survives uninstalling, and Alphabet's search slowdown is now blamed partly on AI Mode earning less per query. Anthropic also reshuffled its Claude subscription tiers and reported that its red-team agents slipped misaligned training data past a monitor. The broader picture covers Google's sleep framework for continual learning, banks setting the terms for agent access, OpenAI's crawler and teen-safety moves, and why Kimi's rank depends on which benchmark version you read.
