币界网报道：Iranian cryptocurrency exchange Nobitex has suffered a major security breach resulting in the theft of approximately $48 million worth of digital assets. The hack, which targeted the exchange's hot wallet infrastructure, is one of the largest crypto thefts in the Middle East this year. Nobitex officials confirmed the incident in a public statement, acknowledging that unauthorized transactions were detected on October 25th. The exchange has temporarily suspended withdrawals while conducting a comprehensive security audit. Preliminary investigations suggest the attackers exploited a vulnerability in the exchange's multi-signature authorization system. Nobitex CEO Amir Hosseini announced immediate measures including migrating remaining funds to cold storage and implementing enhanced security protocols. The exchange has pledged to compensate affected users from its reserves, though the repayment timeline remains unclear. This incident follows a series of high-profile exchange hacks in 2023, raising renewed concerns about security standards in the crypto industry. Blockchain analytics firm Chainalysis has been engaged to trace the stolen funds, which were initially converted to Bitcoin before being dispersed across multiple wallets. Iranian regulators have launched their own investigation into the breach, marking increased government scrutiny of crypto platforms in the country. Nobitex, as Iran's largest digital asset exchange, processes over $10 million in daily trading volume and serves more than 4 million registered users. The hack has prompted calls from industry experts for stricter security requirements and more frequent third-party audits for cryptocurrency exchanges operating in the region.
