Ukrainian Hackers Take Down Russian Fuel Card Systems

The cyber corps of the Main Intelligence Directorate of Ukraine carried out a large-scale operation against Russia's critical infrastructure, blocking fuel cards, attacking the aggressor's telecommunications and online services, and causing significant economic losses.
The Gaze reports on it, referring to Ukrinform.
On September 7, a DDOS attack began on networks that provide online payments for fuel. The main targets were the “advanced payment systems” platform (Rospetrol), as well as the servers of Rostelecom and Lukoil.
According to sources, Russia's losses amounted to between $1 million and $3 million.
Ukrainian specialists also attacked the telecommunications operator K-Corp. More than 700 switches and 13 servers in two data centers were disabled, which completely shut down the company's operations.
K-Corp was chosen because of its cooperation with the Russian defense company Kalashnikov Concern. The company is reported to be involved in the deaths of hundreds of Ukrainian civilians, including women and children.
Cyber experts from the Main Intelligence Directorate also attacked dozens of online resources, resulting in greetings for Ukrainian Military Intelligence Day appearing on the main pages of websites.
As The Gaze reported earlier, American investigators have found evidence that Russia is at least partly responsible for hacking into the federal court document storage system in the United States.
