Across Protocol báo cáo tổn thất ròng dưới 4 triệu USD trong cuộc tấn công vào Solana Relayer

The ME News report states that on July 25 (UTC+8), the cross-chain protocol Across Protocol released a post-incident report on the Relayer security event. The attacker exploited a vulnerability in Risk Labs’ off-chain event reader software on Solana to fabricate 1,627 fraudulent deposit transactions with a total face value of approximately $41.7 million; before suspending Solana services, the Relayer advanced payments for 581 of these transactions, involving approximately $4.5 million of its own capital, while the remaining $37 million in fraudulent deposits have been rendered invalid. This incident did not involve any smart contract vulnerabilities; all user transfers were either completed or fully refunded on the same day. Losses were limited solely to Risk Labs’ own Relayer capital (approximately $4.5 million advanced, with approximately $500,000 of attacker funds deducted, resulting in a net loss under $4 million). Currently, Solana order flow has been fully rerouted through CCTP, and the ACX token buyback program remains unaffected. (Source: Foresight News)
