Incident Overview: Syscoin paused its cross-chain bridge after a validation flaw allowed an attacker to mint approximately 5 billion unauthorized SYS tokens, resulting in a more than 7% drop in SYS over 24 hours, highlighting market concerns over security.
Fund Distribution: The attacker quickly split the minted tokens into two wallets, holding around 4 billion SYS and 1 billion SYS respectively, indicating a rapid movement of funds to evade tracking.
Technical Flaw Analysis: The breach stemmed from a logic gap in the cross-chain code that caused the system to incorrectly accept a fraudulent transaction proof, leading to the minting of nearly 5 billion SYS and exposing vulnerabilities in cross-chain infrastructure.
Follow-up Actions and Market Reaction: The Syscoin team is collaborating with exchanges to freeze affected tokens and is preparing a fix for the validation path; despite a broader market recovery, SYS remains an outlier, trading near $0.0016.
