Syscoin Halts Bridge After Unauthorized Mint of 5 Billion SYS
Syscoin paused its cross-chain bridge after an attacker exploited a validation issue to mint approximately 5 billion unauthorized SYS tokens.
Syscoin has paused its cross-chain bridge after discovering that an attacker exploited a validation issue to mint roughly 5 billion unauthorized SYS tokens on the network's UTXO chain. The project is currently tracing the unauthorized tokens and working with exchanges to prevent the tainted balances from entering open markets.
The incident highlights ongoing security challenges in cross-chain infrastructure. Syscoin operates a hybrid blockchain combining Bitcoin's UTXO model with Ethereum-compatible smart contracts.
