kyivindependent.com - The cyberattack allegedly destroyed large volumes of data and installed custom software designed to further damage the company's information systems.

Cyber specialists from Ukraine's military intelligence agency (HUR) carried out a large-scale cyberattack against the network infrastructure of Russian energy giant Gazprom, causing significant disruptions, a HUR source told the Kyiv Independent on July 18.

The Kyiv Independent could not independently verify these claims. Gazprom and Russian authorities have not publicly commented on the reported incident.

The alleged operation took place on July 17 and targeted systems used by Gazprom and its subsidiaries, which Ukraine's intelligence claims are directly involved in supporting Russia's war effort.

Gazprom is Russia's state-owned energy company, one of the world's largest gas producers and exporters.

The cyberattack allegedly destroyed large volumes of data and installed custom software designed to further damage the company's information systems.

"The degradation of Russian information systems to the technological Middle Ages continues," the source within the HUR told the Kyiv Independent.

"We congratulate Russian 'cyber specialists' on this new achievement and recommend they gradually replace their mice and keyboards with hammers and pincers."
