Published on May 24, 2026 | Translated from Spanish

The ThreatsDay newsletter has published its latest edition with 25 new stories about active cyber threats. The findings include stealthy rootkits in Linux systems, a zero-day vulnerability exploited in home routers, automated AI-driven intrusions, and ready-to-use scam kits. At foro3d.com, we recommend reviewing this report to keep your systems protected.

Rootkits in Linux and Zero-Day in Routers: The Technical Detail 🛡️

The identified rootkits operate at the kernel level, using obfuscation techniques to evade standard detection tools such as LKMs and security modules. The zero-day vulnerability in routers affects mid-range models and allows remote code execution without authentication. AI-driven attacks generate network traffic that mimics legitimate patterns, making filtering difficult. The scam kits include dynamic phishing pages that adapt to the victim's browser.

AI No Longer Just Writes Poems for You, It Also Hacks Your Router 🤖

Now artificial intelligence not only helps you draft emails, but it can also draft your internet disconnection. The scam kits come so well-packaged that even an intern could launch an attack. And the rootkits in Linux are so discreet that the sysadmin finds out when the server starts mining cryptocurrency to pay the attacker's electricity bill.
