Risk to Business: 2.175 = Severe

A Colorado city is putting its IT systems back in order after a successful cyberattack by the BlackCat group. Local media report that following the attack, Wheat Ridge had to shut down its phones and email servers to assess the damage the cybercriminals had done to its network. That, in turn, prompted the city to close down City Hall to the public for more than a week. The cybercriminals demanded $5 million in Monero as the ransom, but the city declined to pay, opting to restore from backups. The city government has been able to return to normal business, and the attack is under investigation by the U.S. Federal Bureau of Investigation.
