In February, attackers from the Russia-based BlackCat ransomware group hit a physician practice in Lackawanna County, Pennsylvania, that’s part of the Lehigh Valley Health Network (LVHN). At the time, LVHN said that the attack “involved” a patient photo system related to radiation oncology treatment. The health care group said that BlackCat had issued a ransom demand, “but LVHN refused to pay this criminal enterprise.”
After a couple of weeks, BlackCat threatened to publish data stolen from the system. “Our blog is followed by a lot of world media, the case will be widely publicized and will cause significant damage to your business,” BlackCat wrote on their dark-web extortion site. “Your time is running out. We are ready to unleash our full power on you!” The attackers then released three screenshots of cancer patients receiving radiation treatment and seven documents that included patient information.
