Odaily Planet Daily reports that the IoTeX team has released an update regarding the ioTube cross-chain bridge security incident that occurred on February 21st. The IoTeX mainnet fully resumed operation at 6:06 AM on February 24th. Mainnet version 2.3.4 permanently blocked 29 attacker addresses and froze approximately 45 million IOTX tokens through an upgrade.
On-chain analysis revealed that the attackers maliciously minted 410 million CIOTX tokens in this incident, of which 99.5% have been locked or frozen, with only 0.4% being liquidated through DEX. The cross-chain bridge reserve assets suffered a cumulative loss of approximately $4.4 million. The attackers exchanged USDC, USDT, and other assets for 2183 ETH, which were then converted into 66.78 BTC via THORChain. Currently, the BTC assets are distributed across four monitored Bitcoin addresses. The IoTeX Foundation has pledged to use government funds to provide 100% compensation to all affected users, with details of the compensation plan to be announced soon.
