The City of Dallas targeted by the ransomware attack that compromised a number of servers in its system, including the Dallas Police Department's website.
The hackers, a collective known as Royal, assert that they encrypted the city's vital data and threatened to leak private information online.
The ransomware gang threatened to divulge information on police informants to the criminal groups they were providing information to.
Cyber specialists think that a phishing email that an employee unknowingly clicked is what started the attack.
