Open-Source Android AI Agents Could Let Invisible Screen Text Run Code on Host PCs

An Android app that can draw over other windows and write to shared storage can slip instructions to the AI agent driving that phone, in text no human eye will ever see. Two more steps, and the same app is running commands on the PC driving the agent.

Researchers demonstrated that chain, plus six other attacks, against five open-source mobile agent frameworks: AppAgent, AppAgentX,

N-day is Becoming N-Hour. Patching Faster Won’t Save You.

New Bit2Watt Attack Could Let Cloud Tenants Disrupt Power Grids Without an Exploit

A cloud tenant using nothing but ordinary GPU access can push a data center’s power draw up and down fast enough to threaten the grid it runs on, with no exploit and no break-in.

That is the claim behind Bit2Watt, described by three Zhejiang University researchers in a paper accepted to CHES 2026, the IACR’s hardware-security conference, and the evidence splits in two: they measured the power
