Grinex, a cryptocurrency exchange based in Kyrgyzstan and previously known as Garantex, has suspended operations following a significant cyber attack that drained approximately 1 billion rubles (around $13 million). The exchange attributed the attack to state-backed actors, indicating a high level of coordination and technical skill. Grinex has been under sanctions from the U.S., U.K., and EU for allegedly assisting users in bypassing financial restrictions. The platform's statement noted that the attack was aimed at inflicting damage on Russia's financial sovereignty. As a result of the breach, users are currently unable to access their funds, and the company is investigating the incident. Grinex has published a list of 54 affected wallet addresses, primarily containing USDT on the TRON blockchain, which were compromised during the attack. The exchange had previously allowed users to conduct transactions through a ruble-backed stablecoin, especially after Russia's access to the SWIFT inter-bank messaging system was restricted due to the ongoing conflict in Ukraine.
