The U.S. State Department announced on Wednesday a reward of up to ten million dollars for information about the ransomware group known as "BlackCat," which breached the technology unit of United Health Group and disrupted insurance payments across the country. The department stated in the reward announcement, "The BlackCat ransomware group (also known as ALPHV) has infiltrated the computer networks of critical infrastructure sectors in the United States and worldwide." United Health Group reported last week that it had begun processing accumulated medical claims exceeding 14 billion dollars, after restoring its services following the cyber attack that caused widespread disruption starting in late February.
