Cybersecurity firms ESET and Broadcom’s Symantec said they discovered a new data wiper malware used in fresh attacks against hundreds of machines in Ukraine, as Russian forces formally launched a full-scale military operation against the country.
The Slovak company dubbed the wiper “HermeticWiper” (aka KillDisk.NCV), with one of the malware samples compiled on December 28, 2021, implying that preparations for the attacks may have been underway for nearly two months.
“The wiper binary is signed using a code signing certificate issued to Hermetica Digital Ltd,” ESET said in a series of tweets. “The wiper abuses legitimate drivers from the EaseUS Partition Master software in order to corrupt data. As a final step the wiper reboots [the] computer.”
