What is a Warlock ransomware attack?

Warlock's a ransomware-as-a-service op, hitting orgs with web shells for access, tunnels for C2, and drivers for persistence. Encrypts fast, extorts hard.

How do web shells work in ransomware?

Hackers upload tiny scripts to web servers via vulns. Instant backdoor. Warlock uses 'em to stage bigger payloads without tripping alarms.

Can I stop Warlock's BYOVD technique?

Hunt unsigned drivers. Use kernel monitoring. Block NSec loads. Reboot often—crude, but it kills persistence.
