"BlackCat Ransomware Cyberattack Causes UnitedHealth Pharmacy Outages"

A cyberattack on UnitedHealth Group's subsidiary Optum, impacting the Change Healthcare payment exchange platform, has been linked to the BlackCat ransomware group. The ongoing outage has led to widespread billing outages across the U.S. healthcare system, with Optum providing daily incident updates and assuring that its own systems have not been affected. While UnitedHealth Group suspects "nation-state" hackers, sources claim the attack is linked to BlackCat, known for over 60 breaches and $300 million in ransom payments. The U.S. State Department is offering rewards for information on the ALPHV gang leaders and individuals linked to BlackCat ransomware attacks.
