Poland's energy grid was targeted by never-before-seen wiper malware
Researchers on Friday said that Poland’s electric grid was targeted by wiper malware, likely unleashed by Russia state hackers in an attempt to disrupt electricity delivery operations.
A cyberattack, Reuters reported, occurred during the last week of December. The news organization said it was aimed at disrupting communications between renewable installations and the power distribution operators but failed for reasons not explained.
On Friday, security firm ESET said the malware responsible was a wiper, a type of malware that permanently erases code and data stored on servers with the goal of destroying operations completely. After studying the tactics, techniques, and procedures (TTPs) used in the attack, company researchers said the wiper was likely the work of a Russian government hacker group tracked under the name Sandworm.
“Based on our analysis of the malware and associated TTPs, we attribute the attack to the Russia-aligned Sandworm APT with medium confidence due to a strong overlap with numerous previous Sandworm wiper activity we analyzed,” said ESET researchers. “We’re not aware of any successful disruption occurring as a result of this attack.
