Hackers from the Ukrainian IT army have paralyzed the operation of the Russian automated enterprise management system 1C-Rarus, as reported by the Ministry of Digital Transformation on Telegram.
“One of the largest ERP systems (Enterprise Resource Planning) in Russia has ceased operation due to attacks by the Ukrainian IT army,” the statement reads.
According to the Ministry of Digital Transformation, currently, users of the service cannot use it. The 1C-Rarus has 150,000 users, including technological giants and sponsors of the war such as “Tatneft” and VTB. Clients in stores and gas stations are unable to make payments because the cash register is not functioning, resulting in significant losses for the Russian economy.
Since Russia’s attack in 2022, Kyiv has called volunteers operating in cyberspace to help Kyiv’s war effort. Hackers, including those in the IT Army of Ukraine, have taken credit for the cyberattacks across Russia and occupied parts of the country. This year, hackers launched 130 attacks on more than 400 pro-Russian targets.
On the morning of 12 December, the largest Ukrainian telecommunications operator Kyivstar, and one of the country’s leading banks Monobank came under a hacker attack.
Kyivstar is Ukraine’s largest mobile operator and one of the country’s biggest broadband Internet providers, with over 24 million mobile customers.
Later, Ukrainian hackers, allegedly affiliated with the Security Service of Ukraine (SBU), launched a cyber operation against Rosvodokanal, Russia’s largest private water supply company with 7 million consumers, Liga media outlet reported, citing an undisclosed source. The source described the operation as “revenge for the attack on Kyivstar.”
On 20 December, the Blackjack hackers group orchestrated a powerful cyberattack, crippling the IT infrastructure of Rosvodokanal. As a result of the operation, the SBU received 1.5 TB of data from Rosvodokanal.
In an affiliated cyber offensive, the IT Army of Ukraine, on 20 December, claimed responsibility for a successful attack on the servers of the Russian cloud service Bitrix24, which is used by entities including the war sponsor Rosneft. This attack resulted in 40% of Bitrix24 users experiencing access issues to CRM systems and other services.
Also, Ukraine’s Main Intelligence Directorate has allegedly attacked Russia’s tax system, destroying the entire database and its backup copies, according to a statement by the intelligence agency. HUR claimed Russia will be unable to fully restore its tax system.
The cyberattack infected all servers with malware, paralyzing communication between the central Moscow office and 2,300 regional Russian tax offices.
According to experts, the paralysis in the work of the Federal Taxation Service of the Russian Federation will last at least a month.
