Roseltorg, Russia’s main electronic trading platform for government and corporate procurement, confirmed it was targeted by a cyberattack claimed by the pro-Ukraine hacker group Yellow Drift. The group allegedly deleted 550 terabytes of data, causing significant operational delays and client concerns. The Record reports: The company initially confirmed last Thursday that its services had been temporarily suspended, without providing further details. In a recent Telegram statement, Roseltorg disclosed that it had been targeted by “an external attempt to destroy data and the entire infrastructure of electronic trading.” Roseltorg stated that all data and infrastructure affected by the recent attack had been fully restored, and trading systems are expected to resume operations shortly. However, as of the time of writing, the company’s website remains offline.

Last week, the previously unknown pro-Ukraine hacker group Yellow Drift claimed responsibility for the attack on Roseltorg, stating they had deleted 550 terabytes of data, including emails and backups. As proof, the hackers published screenshots from the platform’s allegedly compromised infrastructure on their Telegram channel. “If you support tyranny and sponsor wars, be prepared to return to the Stone Age,” the hackers said.

The cyberattack on Roseltorg is already impacting clients who rely on the platform’s operations, including government agencies, state-owned companies and suppliers. Following the company’s announcement, many clients expressed concerns in the comments section, complaining about potential financial losses and delays in the procurement process. Roseltorg said in a statement that once access to the trading systems is reinstated, all deadlines for procedures, including contract signings, will be automatically extended without requiring any requests from users.
