An unknown hacker posted the details of almost 10,000 Department of Homeland Security (DHS) employees online, which he claimed to obtain by hacking the Justice Department, The Hill reported.
The hacker, who tweets from the account @DotGovs, is now threatening to dump the information of 20,000 FBI employees on Monday.
The DHS database appears to be genuine. Ahead of the dump, the hacker shared the information with Motherboard, which conducted a spot check of the database and found most of the entries matched up.
The hacked DHS database includes individuals listed as everything from contractors and special agents to intelligence analysts and technicians.
An agency spokesman said the DHS is looking into the purported disclosure but that “there is no indication at this time that there is any breach of sensitive or personally identifiable information.”
