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 banned 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, of which 99.5% were locked or frozen, and only 0.4% were liquidated through DEX. The cross-chain bridge's 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 exchanged for 66.78 BTC via THORChain. Currently, the BTC assets are distributed across four monitored Bitcoin addresses. The IoTeX Foundation has pledged to use national treasury funds to provide 100% compensation to all affected users; specific compensation plans will be announced soon.
