How Russia-linked malware cut heat to 600 Ukrainian buildings in deep winter

The code was used to sabotage a heating utility in Lviv at the coldest point in the year.

Industrial cybersecurity firm Dragos on Tuesday revealed a newly discovered sample of Russia-linked malware that it believes was used in a cyberattack in late January to target a heating utility in Lviv, Ukraine, disabling service to 600 buildings for around 48 hours. The attack, in which the malware altered temperature readings to trick control systems into cooling the hot water running through buildings' pipes, marks the first confirmed case in which hackers have directly sabotaged a heating utility. Lviv mayor Andriy Sadovyi at the time called the event a “malfunction" in a post to the messaging service Telegram, but added, “there is a suspicion of external interference in the company's work system, this information is currently being checked.” A Lvivteploenergo statement on January 23 described the outage more conclusively as the “result of a hacker attack.”
