New Lotus wiper targets Venezuelan energy and utilities

🔴 Kaspersky researchers analyzed a previously undocumented data-wiping malware, dubbed Lotus, uploaded from a Venezuelan host in mid-December and used in targeted attacks against energy and utility organizations in Venezuela. Before detonation the attacker runs two batch scripts that weaken defenses, change account passwords, log off users, disable network interfaces and run destructive tools like diskpart, robocopy and fsutil to overwrite and fill drives. The Lotus binary then performs low-level IOCTL operations, clears USN journals, deletes restore points and overwrites physical sectors to render systems unrecoverable. Administrators are advised to monitor these precursor activities and maintain offline, validated backups.
