FBI, CISA warn US hospitals of targeted BlackCat ransomware attacks

Image
By Sergiu Gatlan,  Bleeping Computer Today, the FBI, CISA, and the Department of Health and Human Services (HHS) warned U.S. healthcare organizations of targeted ALPHV/Blackcat ransomware attacks. "ALPHV Blackcat affiliates have been observed primarily targeting the healthcare sector," the joint advisory cautions. Today's warning follows an April 2022 FBI flash alert and another advisory issued in December 2023 detailing the BlackCat cybercrime gang's activity since it surfaced in November 2021 as a suspected rebrand of the DarkSide and BlackMatter ransomware groups.

By Bill Toulas, Bleeping Computer Ukraine's computer emergency response team (CERT-UA) has published an announcement warning of ongoing DDoS (distributed denial of service) attacks targeting pro-Ukraine sites and the government web portal. The threat actors, who at this time remain unknown, are compromising WordPress sites and injecting malicious JavaScript code to perform the attacks. These scripts are placed in the HTML structure of the main files of the website and are base64-encoded to evade detection. The code runs on the website visitor's computer and directs their available computational resources to generate an abnormal number of requests to attack objects (URLs) defined in the code. The result is that some of the target websites are overwhelmed by the requests and, as a result, rendered inaccessible to their regular visitors. This all happens without the owners or the visitors of the compromised sites ever realizing it, except for maybe some barely noticeable performan...

By Bill Toulas,  Bleeping Computer Nissan North America (Nissan) suffered a data breach last year when a threat actor targeted the company's external VPN and shut down systems to receive a ransom. The car maker discovered the breach in early November 2023 and discovered recently that the incident exposed personal data belonging to more than 53,000 current and former employees. “As shared during the Nissan Town Hall meeting on December 5, 2023, Nissan learned on November 7, 2023, that it was the victim of a targeted cyberattack. Upon learning of the attack, Nissan promptly notified law enforcement and began taking immediate actions to investigate, contain, and successfully terminate the threat,” the company said in a notification to impacted individuals.

The company notes that none of its systems were encrypted during the attack. Working with extern...
