A campaign active since last November has been targeting Python developers building Telegram bots with trojanized Pyrogram forks that allow attackers to read arbitrary files on compromised servers. […]
Microsoft Warns Poisoned MCP Tool Descriptions Can Make AI Agents Leak Data
New Microsoft research shows how attackers can hijack AI agents that act on a user’s behalf, using nothing more than a poisoned tool description to make the agent quietly hand over company data to an outsider.
The trick is that the agent never breaks a rule. Every step looks routine, so in a default setup no alarm may fire.

RustDuck Botnet Rebuilds in Rust to Hijack Routers and Servers for DDoS
A new two-stage malware family called RustDuck is hijacking home routers, IP cameras, Android boxes, and poorly secured servers, then stitching them into a network built to knock websites and online services offline.

282 iOS AI Apps Leak API Keys and Open AI Proxy Access in Network Traffic Study
Researchers tested 444 AI chatbot apps for iPhone and found that 282 of them, nearly two-thirds, exposed paid AI access through their network traffic.
In many cases, the path in was visible just by watching what the app sent: a plaintext API key, a reusable token, or a backend server that accepted requests with no key at all.
Whoever grabs it can send model requests on the developer’s account,
