PANews reported on February 23 that the IoTeX team tweeted that on February 21, they discovered an attack on the Ethereum side of their multi-chain bridge ioTube. The attackers stole 410 million CIOTX tokens and approximately $4.4 million in assets through four steps. Currently, over 86% of the CIOTX has been locked or frozen, 12.8% (52.4 million CIOTX) is being frozen in cooperation with Binance and other platforms, and only 0.4% (1.7 million CIOTX) remains at risk after being exchanged on DEXs. Regarding the bridge's reserve funds, the attackers exchanged the stolen reserve tokens (including USDC, USDT, WBTC, WETH, and other assets) for approximately 2,183 ETH . Of this, 1,572 ETH has been transferred to the Bitcoin network via THORChain.

The IoTeX team has taken emergency measures, including distributing patch fixes, freezing related addresses, and working with exchanges to freeze funds. The ioTube bridge service will be restored after an independent security audit, along with a compensation plan and security upgrades. The team is committed to ensuring the safety of community assets and will release a more detailed compensation plan and hold a community AMA within the next 48 hours.

Previously reported, IoTeX suffered a loss of approximately $2 million in assets and is expected to be operational within 48 hours . Upbit has added IoTeX (IOTX) to its transaction alert list .
