Ukrainian hackers hit main contractor of Russian Gazprom – media

This was reported by Babel, RBC-Ukraine, and Suspilne.

On February 7-8, 22 more companies involved in the construction and maintenance of Russia's oil and gas infrastructure were also targeted.

In total, over 120 physical hypervisor servers were disabled, and file storage containing 2 million gigabytes (2,000 terabytes) of documentation was destroyed.

Additionally, more than 10,000 computers at critical Russian enterprises were left unusable, halting all systems and services.

Sources estimate the damage could be in the tens to hundreds of millions of dollars.

• In January, Ukrainian hacker group Yellow Drift claimed responsibility for a cyberattack on Roseltorg, a major Russian electronic trading platform, destroying over 550 TB of data.
