Black Basta Ransomware Attack Brought Down Ascension Systems: Report
A cyberattack that affected clinical operations at St. Louis-based Ascension health system was perpetrated by the Russian-speaking ransomware group Black Basta, according to a report.
The group not only executes ransomware but also exfiltrates sensitive data, operating a cybercrime marketplace to publicly release it should a victim fail to pay a ransom. According to one report from blockchain analytics firm Elliptic and cybersecurity risk-focused Corvus Insurance, Black Basta in less than two years has won itself more than $100 million via ransomware schemes from 329 organizations. Ascension, a nonprofit and Catholic health system with 140 hospitals in the U.S., said Wednesday that it initially detected “unusual activity on select technology network systems.” In an update Thursday, Ascension referred to the data breach as a “cybersecurity incident” and said that it was working “around the clock with internal and external advisors to investigate, contain, and restore our systems following a thorough validation and screening process.” The nonprofit had already said that it was using Mandiant to assist in the investigation and remediation process.
