Change Healthcare Ransomware Attack: BlackCat Hackers Quickly Returned After FBI Bust
Two months ago, the FBI “disrupted” the BlackCat ransomware group. They're already back—and their latest attack is causing delays at pharmacies across the US.
Six days before Christmas, the US Department of Justice loudly announced a win in the ongoing fight against the scourge of ransomware: An FBI-led, international operation had targeted the notorious hacking group known as BlackCat or AlphV, releasing decryption keys to foil its ransom attempts against hundreds of victims and seizing the dark web sites it had used to threaten and extort them. In another, more recent bust, the UK's National Crime Agency last week led a broad takedown effort against the notorious Lockbit ransomware group, hijacking its infrastructure, seizing many of its cryptocurrency wallets, taking down its dark web sites, and even obtaining information about its operators and partners. When the FBI targeted BlackCat in December, for instance, the group immediately posted on a newly launched dark web site a message to its partners, promising a higher rate of payment and removing all restrictions on potential victims, other than those in the former Soviet Union, a typical rule for Russia-based cybercriminals.
