IoTeX is reportedly facing a significant security breach, with a suspected private key leak leading to the theft of approximately $4.3 million in assets. On-chain analyst Specter highlighted the incident, noting that all assets from IoTeX's token treasury were stolen. The attacker allegedly transferred assets from various contracts, including USDC, USDT, IOTX, PAYG, WBTC, and BUSD. The stolen assets were subsequently converted into Ethereum, with about 45 ETH moved via a cross-chain bridge to the Bitcoin network. The incident remains under investigation, and the disclosed attacker address is 0x6487B5006904f3Db3C4a3654409AE92b87eD442f1PN2BoHU4buDQWcrNHk9T9NBA2qX8oyYEc135oSa2fobTxtHtm5dwTREDyRY2o1DG1Aw.
