ShellBot Targets Exposed Linux SSH Servers With Three New Variants

In a new campaign, the Perl-based DDoS bot malware ShellBot (also known as PerlBot), which was previously used in assaults alongside CoinMiner, targets poorly maintained Linux SSH servers. Threat actors use three new malware variants - LiGhT's Modded perlbot v2, DDoS PBot v2.0, and PowerBots (C) GohacK.  Administrators are suggested to implement strong password policies.
