Ransomware Groups Are Bouncing Back Faster From Law Enforcement Busts
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 disrupting the BlackCat ransomware group, the Justice Department has once again hacked the hackers,” deputy attorney general Lisa Monaco declared in a statement.
Two months and one week later, however, those hackers don't appear particularly “disrupted.” For the last seven days and counting, BlackCat has held hostage the medical firm Change Healthcare, crippling its software in hospitals and pharmacies across the United States, leading to delays in drug prescriptions for an untold number of patients.
The ongoing outage at Change Healthcare, first reported to be a BlackCat attack by Reuters, represents a particularly grim incident in the ransomware epidemic not just due to its severity, its length, and the potential toll on victims' health. Ransomware-tracking analysts say it also illustrates how even law enforcement's wins against ransomware groups appear to be increasingly short-lived, as the hackers that law enforcement target in carefully coordinated busts simply rebuild and restart their attacks with impunity.
