Cysic crypto bridge halted after unauthorized mint of 10M CYS
Summary
Cysic suspended its BNB Smart Chain bridge after an attacker exploited a processing flaw to mint 10 million CYS, with preliminary findings suggesting unauthorized access to a bridge-supporting database. Cysic blacklisted the recipient address about 76 minutes later; roughly 2.8 million CYS remained there with transfers restricted. The company said the incident was limited to bridge processing and minting, with no impact on its mainnet or theft of assets from user wallets. The dollar impact is still unknown while transfers, swaps and losses are investigated. Cysic hired a security firm and plans to publish a follow-up report.
