ThreatsDay: Linux rootkits, router 0‑day, AI attacks and leaks — what to know

ThreatsDay: Linux rootkits, router 0‑day, AI attacks and leaks — what to know

Colleagues, a note for cyber defenders: the ThreatsDay review highlights increased exploitation of trusted components.

Briefly:
- 47 zero‑days at Pwn2Own; exploits targeting Windows, Linux, VMware, and more.
- OrBit — an active Linux rootkit now seen in ransomware campaigns.
- Agent‑style AI campaigns (SHADOW‑AETHER) speeding reconnaissance and exploit generation.
- Cloud/trusted vectors: Composer token leak, SSPR/MFA phishing (Storm‑2949), and a router 0‑day causing a major outage.

Why it matters: attacks increasingly hide behind legitimate processes and services.

What will you change in your defenses?
