Hundreds of US government officials working for the FBI, ICE, and Department of Justice have had their personal data leaked by a notorious hacking group.

A group of hackers from The Com - a loosely-organised collective of English-speaking hackers, scammers and fraudsters - has shared the names, addresses, and phone numbers of hundreds of US government employees on private Telegram channels, according to a report by 404 Media.

404 Media says that it has reviewed spreadsheets posted to the hacking group's Telegram channel containing the alleged personal data of 680 DHS officials, over 170 FBI email addresses, and more than 190 Department of Justice officials.

It is presently unclear where the data originated.

Earlier this week, the US Department of Homeland Security claimed that criminals based in Mexico have instructed gang members in Chicago to monitor, harass, and assassinate agents of United States Immigration and Customs Enforcement (ICE) and Customers and Border Protection (CBP) personnel. Bounties have allegedly been offered to shoot ICE and CBP officers, according to a DHS press release.

According to the report from 404 Media, one member of the Telegram channel left a message saying:

“Mexican Cartels hmu [hit me up] we dropping all the doxes wheres my 1m [1 million]."

The Com, which is affiliated to various hacking groups including BlackCat, ALPHV, and Scattered LAPSUS$ Hunters, has been linked to high-profile hacks against the likes of MGM Resorts, Coinbase, Clorox, and many others.

Earlier this month, the DHS made the unsubstantiated claim that ICE officers were facing a "more than 1000% increase in assaults against them" and that their families were being doxxed and threatened online.

Now the hackers who posted the details of ICE, DHS, and CBP staff to Telegram have suggested that they may dox IRS officials next.

In 2016, a group called Crackas With Attitude, published the personal information of thousands of FBI and Department of Homeland Security agents. and even hacked into the AI account of the director of the CIA.
