On October 28th, 2020 multiple government agencies released a joint alert regarding “credible information of an increased and imminent cybercrime threat to U.S. hospitals and healthcare providers”. The alert covers specific details for two common versions of ransomware, Trickbot and Ryuk. It also goes into more general procedures for mitigating the risk of and recovering from ransomware.

  • Have a plan for audit logs and regularly review them

Backups:
