Security researchers say they’ve just lately noticed a Russian hacking crew, who have been behind the damaging WhisperGate malware cyberattacks, focusing on Ukrainian entities with a brand new information-stealing malware.
Symantec’s Threat Hunter Team has attributed this marketing campaign to a Russia-linked cyber menace actor, broadly referred to as TA471 (or UAC-0056), which has been lively since early 2021. The group is recognized to assist Russian authorities pursuits, and whereas it primarily targets Ukraine, the group has additionally been lively in opposition to NATO member states in North America and Europe. TA471 has been linked to WhisperGate, a damaging data-wiping malware that was utilized in a number of cyberattacks in opposition to Ukrainian targets in January 2022. The malware masquerades as ransomware, however renders focused units utterly inoperable and unable to recuperate recordsdata even when a ransom demand is paid.
According to Symantec, the hacking crew’s newest marketing campaign depends on beforehand unseen information-stealing malware it calls “Graphiron” for focusing on Ukrainian organizations. The malware was used to steal information from contaminated machines from October 2022 till at the least mid-January 2023, based on the researchers, cheap to imagine that it stays a part of the [hackers’] toolkit.”

But Symantec says that Graphiron is designed to exfiltrate way more information, together with screenshots and personal SSH keys.
