Cysic Cross-Chain Bridge Paused After Unauthorized Minting of 10 Million CYS Tokens

Odaily reports: The crypto project Cysic has announced that its cross-chain bridge was paused on Saturday after an attacker exploited a processing flaw to mint 10 million CYS tokens without authorization on BNB Smart Chain. Preliminary investigations indicate that the attacker may have gained unauthorized access to the database supporting the bridge.

The unauthorized minting occurred at 12:31:38 UTC, and Cysic blacklisted the receiving address in the token contract at 13:47:52. The address currently still holds approximately 2.8 million CYS, and related transfers have been restricted.

Cysic stated that the incident only involved cross-chain bridge message processing and token minting, and did not affect the mainnet or other operating systems, nor did it result in the theft or unauthorized transfer of existing CYS or other assets in user wallets. Token transfers, swaps, and actual losses are still under review, and the company has engaged security firms and plans to release a follow-up report. (Cointelegraph)
