Syscoin Suspends Bridge Services After 5 Billion SYS Cross-Chain Security Incident

Syscoin said it has paused its bridge services following a recent cross-chain bridge security incident involving 5 billion SYS tokens. According to PANews, the team is investigating and fixing a verification issue in the bridge process. Syscoin stated that an attacker exploited a verification vulnerability in the cross-chain bridge workflow to create unauthorized SYS outputs on the UTXO side. The project said the affected funds have been moved and split. Syscoin said it is tracking the funds and coordinating with exchanges and ecosystem partners to prevent contaminated UTXOs from being deposited, traded, or further distributed. The team added that it has identified a fix and advised users not to interact with the bridge until services resume.
