Data-destroying Malware Target Ukrainian Organizations

Share post:

ESET researchers have uncovered a new strain of data-destroying malware targeting Ukrainian organizations.

Known as CaddyWiper, the malware can wipe data across compromised Windows domains.

Data on the domain controller are not affected during the attack. It is assumed that by not deleting data on the domain controller, the attackers can maintain access inside the compromised networks.

“This new malware erases user data and partition information from attached drives. ESET telemetry shows that it was seen on a few dozen systems in a limited number of organizations,” ESET Research Labs explained.

CaddyWiper is the fourth data wiper deployed in Ukraine in 2022. ESET researchers discovered two other data wipers including HermeticWiper and IsaacWiper.

Microsoft discovered the last of the four data wipers tracked as WhisperGate. WhisperGate was disguised as ransomware and used in data-wiping attacks against Ukraine in mid-January.
