When hackers struck the Colorado Department of Transportation in a ransomware attack in February and again eight days later, they disrupted the agency's operations for weeks.
State officials had to shut down 2,000 computers, and transportation employees were forced to use pen and paper or their personal devices instead of their work computers. Staffers whose computers were infected didn't have access to their files or data, unless it was stored on the internet, and the attack affected the payroll system and vendor contracts.
It could have been a lot worse: The Colorado hacks didn't affect traffic signals, cameras or electronic message boards, and state information technology officials, who refused to pay the ransom, said the system had been 95 percent restored as of last week.
