ALEX releases security incident update: The attacker's on-chain balance is approximately 5.56 million STX

On June 17th, Bitcoin DeFi platform ALEX Lab released a security incident update. As of 11am on June 17th, the attacker had broadcasted over 9700 transactions, involving the creation of new wallet addresses and dispersing STX balances on the chain to these new wallets. The number of trackable transactions began to exponentially grow from 300 to over 9600 and has been accelerating without any signs of stopping. This also means that the attacker's independent address count has increased from less than 100 to over 4700 in 7 days.

A small amount of STX was transferred to thousands of new addresses and then sent to CEX. Most CEXs have fully cooperated with us in the recovery process, however, the attacker realized this and quickly switched to sending the stolen funds to CEX addresses. The current traceable amount of STX deposited into CEX is 8,373,587 STX, and the attacker's current on-chain balance is approximately 5,560,332 STX (calculated based on wallet balances exceeding 100 STX).
