Executive Summary

A weekly bulletin covering Linux rootkits, a router zero-day, AI-assisted intrusions and scam kits.

What Happened

This week starts small. A token leaks. A bad package slips in. A login trick works. An old tool shows up again. At first, it feels like the usual mess. Then you see the pattern: attackers are not always breaking in. They are using the parts we already trust. That is what makes it worrying. The danger is in normal things now - updates, apps, cloud buttons, support chats, trusted accounts. AI
