Security experts sound alarms on AI agents

Microsoft warned companies that AI agents built on models from outside major labs can act like insider threats. Separately, a hacker used a group of AI agents to break into over 100 websites, including John Deere and SharkNinja. Hackers also breached the AI coding tool OpenCode, stealing API keys and running up charges on users' accounts.

Why it matters & sources

Why it matters: As companies hand more tasks to autonomous AI agents, these incidents show real gaps in how that access gets secured.

Challengers line up against Nvidia's chip dominance

Amazon released a tool called TorchNeuron to help developers run AI software on chips other than Nvidia's. Chip designer Tenstorrent raised $1.5 billion, reaching a $6.2 billion valuation, to keep building open-weight AI chips as an alternative. Alibaba said its RISC-V chip design has now shipped in over 6 billion chips, as it expands into AI and automotive uses.

Why it matters & sources

Why it matters: More serious alternatives to Nvidia could change who controls the hardware behind AI systems.
