The City of Dallas was targeted by the Royal ransomware gang, which later rebranded as BlackSuit. The attack involved the deployment of ransomware, leading to significant operational disruptions and potential data breaches. The cybercriminals used double-extortion tactics, encrypting systems and threatening to leak stolen data to coerce payment. The attack was part of a broader campaign that affected over 450 victims in the U.S., including sectors like healthcare, education, and government. The financial impact was substantial, with ransom demands exceeding millions of dollars.

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.
