      Cysic Suspends Crypto Bridge Following Unauthorized Mint of 10 Million CYS Tokens

      Cysic has temporarily halted its cross-chain bridge after an unauthorized minting of 10 million CYS tokens on the BNB Smart Chain occurred on October 17, 2026. The company blacklisted the address that received the tokens shortly after the incident, which took place at 12:31:38 UTC. By the time the address was blacklisted at 13:47:52 UTC, approximately 2.8 million of the minted tokens were still in that address, indicating that a significant portion had already been moved before the freeze was implemented.

      The incident has been characterized by Cysic as limited to the bridge's message processing and minting functions, with assurances that the mainnet and other operational systems remain unaffected. However, the bridge will remain offline indefinitely, and no timeline for its reopening has been provided. Cysic has engaged third-party security experts to investigate the breach and is monitoring the movement of the exploited tokens to determine if they are being swapped or transferred elsewhere.

      This incident highlights ongoing vulnerabilities in crypto bridge systems, particularly regarding minting functions that lack adequate safeguards. Similar issues were observed in a previous incident involving Syscoin in June 2026. Cysic operates a dual-token model, with CYS serving as the utility token and CGT for governance, and the unauthorized minting incident raises concerns about potential dilution for CYS holders, as only a fraction of the minted tokens are currently frozen. The investigation is ongoing, with early findings suggesting a possible link to unauthorized access to off-chain databases, which could indicate broader security weaknesses beyond just smart contract vulnerabilities.
