On Tuesday, a ransomware gang that hacked the Metropolitan Police Department of the District of Columbia in April shared highly sensitive details of nearly 24 police officers.

According to the reports, the data of the police officers were released after the ransomware gang identified as Babuk could not agree with MPD on the amount to be paid.

While Babuk demanded $4 million, NPD negotiators offered $100,000, according to the transcript.

Details shared by the group include driver’s license photos, fingerprints, social security numbers, dates of birth, home, marriage, and financial histories, as well as results of police psychological examinations and polygraph tests.

While the NPD did not respond to questions about the authenticity of the data published by Babuk, web searches revealed that three of the names listed in the personnel files matched the names of officers working for the MPD.
