The notorious Russian threat group is spreading an upgraded version of the botnet malware, which the FBI disrupted in 2022.

Editorial Analysis

Why it matters

Sandworm's ability to rebuild disrupted botnet infrastructure using fresh Cisco exploit chains underscores the persistent threat to European critical-infrastructure operators still running unpatched edge devices.

What to do

Audit all Cisco edge devices against the referenced CVEs immediately and restrict management-plane access to trusted networks only.

Board brief

Russia's most dangerous cyber unit has revived its botnet by exploiting Cisco network devices, posing a direct risk to European infrastructure.
