The Washington, D.C., police department was hit by a ransomware attack.
The Russian hackers claimed to have 250GB of sensitive data and threatened to release it to local gangs. They gave the department three days to contact them and warned they "will start to contact gangs in order to drain the informants."
The hackers shared screenshots of the data, which included reports, arrest logs, and files about ongoing investigations.
The FBI is investigating the breach, as the cyberattack have not impacted any police operations.
"We are aware of unauthorized access on our server. While we determine the full impact and continue to review activity, we have engaged the FBI to fully investigate this matter," the department said in a statement.
A group known as Babuk claimed responsibility for the attack and the same group was also responsible for a cyberattack against the Houston Rockets earlier this month.
