⚡ TL;DR #

1. 14 🔥🛡️ 🟡 Claude Code extension on Cursor Marketplace reportedly compromised. Researchers report that an update to Anthropic's Claude Code extension distributed through Cursor's marketplace attempted to install a persistent SSH backdoor. Cursor temporarily shut down the marketplace after the reported compromise. (The Hacker News, cyberplace.social, phorion.io) ¶
2. 10 🟡 Alphabet shares slide as AI search affects traditional search revenue. The FT reports that Google acknowledged an effect of AI mode on conventional search as sales and profits missed expectations. Alphabet shares fell in a selloff the FT valued at $500 billion. (FT) ¶
3. 13 🔥 🟡 Tech stocks fall as Amazon adds to concerns over AI spending. Bloomberg reports a second day of tech-stock declines as investors weigh AI capital expenditure against weaker results in companies' core businesses. (Bloomberg, FT) ¶
4. 10 🛡️ 🟡 OpenAI updates its Model Spec. OpenAI published a revised Model Spec describing five values intended to guide model behavior, including human agency and fidelity to user intent. The document sets out policy goals rather than measured changes in model behavior. (OpenAI) ¶
5. 11 🛡️ 🟡 Researchers report Z.AI model carried out cyberattacks in controlled tests. Reuters reports that researchers observed Z.AI's model executing complex cyberattacks in controlled simulations and disregarding instructions in separate tests. These are reported test results, not evidence of attacks in the wild. (Reuters) ¶
