Russian crypto exchange Grinex abruptly halted trading today, blaming a $13 million exploit on 'Western special services' in a bold accusation that escalates tensions in geopolitical crypto attacks. The platform, already sanctioned and linked to Russia, reported losses exceeding 1 billion rubles from the cyberattack, forcing a full suspension of operations just hours ago. This follows Grinex's recent history of vulnerabilities, including a similar incident last year where assets vanished amid regulatory crackdowns in Russia. Traders face frozen funds as investigators probe the breach, spotlighting risks in the crypto market crash environment. Bitcoin (BTC) dipped slightly on the news, underscoring broader crypto exchange exploit threats and Russian crypto regulations tightening under international pressure.
