DataSuckers is a financially motivated hacking group linked to major data breaches affecting businesses in Russia and Ukraine, with claims of having stolen 2-3 TB of data from approximately 68 million customers. The group has demonstrated TTPs such as customer data theft, extortion through ransom demands, and website defacement. They have claimed responsibility for high-profile attacks on ATB Market, Dodo Pizza, and Tez Tour, and reportedly obtained sensitive customer and employee information during these breaches. While DataSuckers maintains a Telegram channel for communications, its operations have drawn the attention of Russian authorities, resulting in the detention of several key members.
