CNA ransomware attack

CNA, a US insurance giant, paid $40 million ransom to recover its systems in March.  This was one of the largest payments so far.  The attack was carried out using Phoenix CryptoLocker believed to have been used by Evil Corp a Russian cybercrime Network.  Since the pandemic there has been a large increase in the number of ransomware attacks and ask payments by hackers.  To defend against ransomware attacks, companies should secure all modes of initial access used to infiltrate networks, maintain regular data backups, and develop and use an appropriate recovery.
