The UwU Lend protocol, previously targeted in a nearly $20 million hack on June 10, is facing an ongoing cryptocurrency exploit that has so far resulted in the theft of $3.7 million.
This development comes as the protocol has been making efforts to reimburse its users following the $19.3 million June 10 hack.
$3.7 Million Hack
Cyvers, an on-chain data analytics platform, was the first to alert UwU Lend about the ongoing exploit. According to its findings, the bad actors behind this latest incident appear to be the same as those responsible for the earlier $19.3 million heist.
