Three Russian firms have over 400 GB worth of emails leaked

Hackers published close to 437,500 emails from Russian companies Petrovsky Fort, Aerogas, and Forest.

Distributed Denial of Secrets, or DDoSecrets, revealed a large dump of data the Anonymous collective took from several Russian companies.

The leak includes 300,000 emails weighing 244 GB from Petrovsky Fort, owner of one of the largest office complexes in Russia's second-largest city Saint-Petersburg.

Another 100,000 emails (145 GB) belong to Aerogas, a Russia-based engineering company catering to the country's oil and gas sector.

According to Aerogas' website, the company's clients include Russia's largest oil producer Rosneft, and the country's largest natural gas producer Novatek. Both companies are state-owned.

Hackers also leaked over 37,500 emails (35.7 GB) from Forest, a Russian logging company.

According to DDoSecrets, the site has published over 2 million emails since Russia started a war against Ukraine at the end of February.

The leak is just the latest installment in a cascade of 'smash and grab' cyberattacks hackers and cyber activists carried out against Russia over Moscow's invasion of Ukraine on the night of February 24.

Recently hackers dumped close to 800 GB of data belonging to the All-Russian State and Radio Company (VGTRK), the Kremlin's propaganda branch.

Another recent leak, published by DDoSecrets, contains 5,500 emails from Thozis Corp., a Russian investment firm owned by a Russian businessman Zakhar Smushkin.

The hacker community started rallying to help Ukraine. Anonymous, Ukraine's IT Army, Hacker Forces, and many other hacktivist groups target Russia's state-owned enterprises and businesses.

Russian nuclear agency Rosatom, the country's space agency Roscosmos, state-owned energy corporation Gazprom and many others were also breached by hacktivists protesting the war.

According to the United Nations, the Russian invasion of Ukraine has created the 'fastest-growing refugee crisis in Europe since World War II.' Over 10 million people were displaced due to the conflict, with over 4.3 million fleeing the country.

Witness testimonies from Ukrainian towns Russian forces have occupied for close to a month point to human rights violations and targeted attacks against civilians. Reports of "gross and systematic violations and abuses of human rights" got Russia suspended from the UN Human Rights Council.
