      "what_changed_en": "Cysic added that the attack occurred on October 17 after the attacker gained access to a database related to the cross-chain service and submitted false mint messages; the incident was limited to the bridge's message-processing and minting functions, did not affect the Cysic mainnet or existing assets in user wallets, and the team hired a security firm to investigate the attack path and trace funds.",

      "background_en": "Cysic describes itself as a full-stack compute network (ComputeFi), and its CYS token, per the project's tokenomics documentation, coordinates incentives among users, compute providers, governance participants and contributors. Cross-chain bridges have repeatedly been a leading attack vector in decentralized finance, with flaws typically arising in message verification, validator trust or operational key and database access.",

      "market_impact_zh": "风险敞口集中在 BNB Smart Chain 上的 CYS 流动性：跨链桥已暂停，切断了 CYS 在网络间流转的跨链通道；同时约 280 万枚未经授权铸造的代币滞留在被拉黑地址中无法转移。若该笔铸造中仍有未被拉黑的部分，则构成新增供应对代币形成潜在抛压，最终损失规模取决于基金会正在进行的资金追踪核查结果。",
      "market_impact_en": "The exposure is concentrated in CYS liquidity on BNB Smart Chain: the bridge has been paused, cutting the cross-chain channel that moves CYS between networks, while roughly 2.8 million of the unauthorized tokens sit in a blacklisted address that cannot transfer them. Any remaining unblacklisted portion of the mint would represent newly created supply overhanging the token, and the eventual loss figure depends on the foundation's ongoing fund-tracing review.",
