Microsoft Documents Over 200 Cyberattacks by Russia Against Ukraine
At least six different Russia-aligned actors launched no less than 237 cyberattacks against Ukraine from February 23 to April 8, including 38 discrete destructive attacks that irrevocably destroyed files in hundreds of systems across dozens of organizations in the country.
“Collectively, the cyber and kinetic actions work to disrupt or degrade Ukrainian government and military functions and undermine the public’s trust in those same institutions,” the company’s Digital Security Unit (DSU) said in a special report.
The major malware families that have been leveraged for destructive activity as part of Russia’s relentless digital assaults include: WhisperGate, HermeticWiper (FoxBlade aka KillDisk), HermeticRansom (SonicVote), IssacWiper (Lasainraw), CaddyWiper, DesertBlade, DoubleZero (FiberLake), and Industroyer2.
WhisperGate, HermeticWiper, IssacWiper, and CaddyWiper are all data wipers designed to overwrite data and render machines unbootable, while DoubleZero is a .NET malware capable of data deletion. DesertBlade, also a data wiper, is said to have been launched against an unnamed broadcasting company in Ukraine on March 1.
SonicVote, on the other hand, is a file encryptor detected in conjunction with HermeticWiper to disguise the intrusions as a ransomware attack, while Industroyer2 specifically targets operational technology to sabotage critical industrial production and processes.
