The CISA and FBI have released a joint advisory detailing the threats posed by a new Ransomware-as-a-Service (RaaS) variant, referred to as DarkSide.  DarkSide was recently used in a ransomware attack against a critical infrastructure company and the CISA, and FBI see these attacks as growing in the near future.  The advisory contains a number of mitigation steps to protect yourself against this and other variants.  More detail can be found at – https://us-cert.cisa.gov/ncas/alerts/aa21-131a
