Cybercriminals have allegedly stolen a large amount of sensitive internal documents from the Los Angeles Police Department and leaked the data online. The stolen data included police officer personnel files, internal affairs investigations, and discovery documents that can include unredacted criminal complaints and personal information. The LAPD said the breach affected 'a digital storage system' belonging to the city's Attorney's Office.

Why it matters

This breach represents a significant compromise of sensitive police data, which is rarely disclosed or published under California state law. The leak could have serious implications for the privacy and security of police officers, witnesses, and others involved in criminal investigations.

The details

The group posted the stolen data on its leak website in an attempt to pressure the LAPD into paying a ransom, but the data has since been removed from the site.
