McLaren Health Care Ransomware Attack Affects 2.1 Million Patients
McLaren Health Care, a 14-hospital health system based in Grand Blanc, Michigan, has confirmed that it recently fell victim to a ransomware attack and has warned patients that files containing patient information were stolen in the attack and may be leaked on the dark web. Suspicious activity was detected in its IT systems in late August, and it was later confirmed that this was a ransomware attack. Its computer network was taken offline while the incident was investigated, which caused disruption across its healthcare facilities, although healthcare services continued to be provided at all locations and patient care was unaffected Last week, the ALPHV/BlackCat ransomware group claimed responsibility for the attack and added McLaren Health Care to its dark web data leak site. ALPHV is a spin-off of the now-defunct Conti ransomware group and has a history of attacking healthcare organizations. The group claims to have exfiltrated more than 6 terabytes of data in the attack and says the stolen data includes the sensitive information of 2.5 million patients. While McLaren Health Care...

The malware is now better at evading security solutions, has more extensive capabilities, and...

FBI Sounds Alarm About Dual Ransomware Attacks and Data Wiping Tactics
The tactics, techniques, and procedures (TTPs) used by ransomware gangs often evolve, and with increasing numbers of victims refusing to pay ransoms, ransomware groups have started adopting more aggressive tactics. Two concerning new ransomware trends have been identified by the Federal Bureau of Investigation (FBI) – Ransomware groups are conducting dual attacks on victims using multiple ransomware variants and have been observed employing data destruction tactics using custom wiper tools when victims refuse to engage and discuss ransom payments. The FBI has previously warned that paying the ransom following a ransomware attack provides no guarantee that files can be recovered and victims that pay may be subject to further extortion demands. The latest warning concerns dual ransomware attacks, where two attacks are conducted using different ransomware variants in close proximity against the same target. This tactic was first observed by the FBI in July 2023 with the attacks involving various combinations of ransomware variants from the AvosLocker, Diamond, Hive, Karakurt, LockBit,...
