The Switch Hackers caused a blackout for the first time, researchers say

Hackers caused a power outage in Ukraine during holiday season, researchers say, signalling a potentially troubling new escalation in digital attacks.

"This is the first incident we know of where an attack caused a blackout," said John Hultquist, head of iSIGHT Partner's cyberespionage intelligence practice. "It's always been the scenario we've been worried about for years because it has ramifications across broad sectors."

Half of the homes in Ukraine's Ivano-Frankivsk region were left without power for several hours on December 23rd, according to a local report that attributed the blackout to a virus that disconnected electrical substations from the grid. Researchers at iSight on Monday said their analysis of malware found on the systems of at least three regional electrical operators confirmed that a "destructive" cyberattack led to the power outage.

Electrical outages can lead to ripple effects that leave communities struggling with things like transportation and communication, according to security experts who have long warned about the potential for cyberattacks on the power grid. (by Andrea Peterson, Washington Post)
