A group of hackers reportedly posted over 120,000 files from BART’s police department that include the names of children suspected of suffering abuse, driver’s license numbers and mental health evaluation forms, according to a report in NBC News.

The hack appeared to be the work of Vice Society, a notorious criminal group that has targeted schools, hospitals, and public agencies around the world with ransomware attacks. Last week Brett Callow, a cybersecurity analyst at Emsisoft, said the group listed BART as the target of an attack.
