A cyberattack on USIS, formerly known as US Investigations Services, a company that conducts background checks for federal government employees, compromised the personal data of at least 25,000 of those workers, including undercover investigators. For example, the breach exposed personal information of Department of Homeland Security (DHS) employees. The compromised information includes Social Security numbers, education and criminal history, birth dates, and personal information about relatives and friends. Dmitri Alperovitch, chief technology officer with cybersecurity firm CrowdStrike, said hackers “would be collecting this data to identify individuals who might be vulnerable to extortion and recruitment.” USIS disclosed the attack earlier this month—saying it has “all the markings of a state-sponsored attack”—but did not say how many records had been compromised or which agencies were affected. DHS suspended all work with the company and the FBI is investigating the attack. USIS could not be reached for comment. (Reuters)(NBC News)
