A gang of cybercriminals said it hacked the Washington D.C. Metropolitan Police Department on Monday, claiming to have stolen more than 250 gigabytes from the law enforcement agency. 

The gang, known as Babuk, published the claim on its official website, where the hackers post some of the stolen files from their victims in an attempt to extort them. The goal is to scare the victim into paying before the hackers release all the information.
