In a significant global law enforcement operation, the notorious ransomware group LockBit has been dismantled, with its infrastructure seized and several members arrested. The operation, dubbed 'Operation Cronos', involved agencies from the UK, US, and EU, targeting the group responsible for a series of high-profile cyber attacks, including on Royal Mail. Ransomware costs have surged to $1.1 billion in 2023, nearly doubling from $567M in 2022 and up 5x from $220M in 2019, highlighting the growing threat of cybercrime. The crackdown on LockBit, described as the world's most harmful cybercrime group, involved the seizure of dark web sites, the arrest of members in Poland and Ukraine, and the release of decryption keys. Two Russian nationals have been indicted in the US, with a total of five Russian nationals charged. The operation marks a significant victory in the fight against cybercrime, with law enforcement seizing over 200 crypto wallets and disrupting the largest ransomware group, which was behind 21% of all attacks in 2023. Additionally, over 80 organizations in Europe were targeted in a cyberespionage campaign exploiting vulnerabilities in Roundcube webmail servers. Meta Platforms took action against 8 spyware firms targeting users across various devices. The LockBit group's compromise was facilitated by exploiting CVE-2023-3824.
