Cosine: Received multiple reports of stETH being stolen and transferred across chains to the Blast mainnet, possibly a collective incident

ChainCatcher news, Slow Mist founder Yu Xian tweeted: "Today, Slow Mist and MistTrack received at least four cases of stETH being stolen and cross-chained to the Blast mainnet. The characteristic is that a small amount of ETH fees is transferred from obviously traceable addresses (including exchanges) to the stolen address, followed by cross-chaining the stETH to the Blast mainnet and subsequent transfers, and finally transferring the remaining small amount of ETH from the victim's address to different ETH addresses.

The known loss exceeds 100 stETH, and it is likely a collective incident. The mnemonic phrases/private keys of these victims must have been leaked, and the attackers are lying in wait to launch on the Blast mainnet."
