Cryptocurrency Exchange Grinex Suspends Operations Following $13 Million Cyber Heist

A prominent cryptocurrency exchange, Grinex, which was popular among Russian users seeking to circumvent sanctions, has temporarily ceased operations after falling victim to a sophisticated cyber attack that resulted in the theft of approximately 1 billion rubles, equivalent to $13 million. The exchange, which is based in Kyrgyzstan, revealed the breach via its Telegram channel and an official statement on its website, attributing the attack to state-sponsored actors from 'unfriendly nations' due to the high level of coordination and technical expertise involved. According to Grinex, preliminary data suggests that the attack was deliberately orchestrated to undermine Russia's financial autonomy. The exchange had previously been sanctioned by the US, UK, and EU for its role in enabling users to bypass restrictions through a ruble-backed stablecoin called A7A5, which facilitated cross-border transactions after Russia's access to the Swift inter-bank messaging system was suspended following its invasion of Ukraine. Following the sanctions, the platform re-emerged as Grinex. The current suspension of trading activities has left users without access to their funds while the company conducts an investigation. Additionally, access to Grinex's Moscow office has been restricted. The exchange has released a list of 54 affected wallet addresses and the corresponding amounts that were drained, with the majority of the stolen funds being in the form of USDT on the TRON blockchain.
