Ransomware Attack by BlackCat Disrupts US Prescription Services

The BlackCat ransomware group is behind a cyberattack on Change Healthcare, causing widespread outages and affecting pharmacies and healthcare facilities across the U.S.

The cyberattack began on February 21, leading to significant disruptions in prescription processing and insurance claims.
Change Healthcare, a major U.S. health tech company, attributed the attack to the BlackCat ransomware group, impacting over 67,000 pharmacies.
UnitedHealth Group, the parent company, identified a 'suspected nation-state' threat but did not link the attack to any specific government.
The attack has caused pharmacies to resort to backup systems, leading to delays and backlogs in prescription processing.
Efforts to restore services are ongoing, with nearly all customer-facing systems of Change Healthcare still offline.
