A potential suspect has been identified over the $8.5 million attack on decentralized finance protocol Platypus, which saw $8.5 million drained from the protocol.

ក្រុមហ៊ុនសន្តិសុខ Blockchain CertiK ដំបូងបានរាយការណ៍ពីការវាយប្រហារប្រាក់កម្ចីភ្លាមៗនៅលើវេទិកាផ្លាស់ប្តូរស្ថេរភាពដែលមានមូលដ្ឋានលើ Avalanche តាមរយៈ tweet នៅថ្ងៃទី 16 ខែកុម្ភៈ រួមជាមួយអាសយដ្ឋានកិច្ចសន្យារបស់អ្នកវាយប្រហារដែលត្រូវបានចោទប្រកាន់។

According to CertiK, nearly $8.5 million has been already been moved. As a result, the Platypus USD stablecoin became de-pegged from the U.S. dollar, ទម្លាក់ 52.2% ទៅ 0.478 ដុល្លារនៅពេលសរសេរ។

Platypus later confirmed the hack on Twitter, while a moderator of Platypus’ Telegram group confirmed that Platypus has halted trading.

“The attacker used a flashloan to exploit a logic error in the USP solvency check mechanism in the contract holding the collateral.”

Platypus confirmed a loss of “8.5 million” from its main pool and said that deposits were covered at 85%. Other pools were unaffected. The company has contacted the hacker to negotiate a bounty for the return of the funds.

Tether Holdings has frozen the USDT stolen, and Platypus had reached out to Circle and Binance to freeze other stolen tokens.

A tweet from crypto “on-chain sleuth” ZachXBT has called out a now-deleted Twitter account going by @retlqw, alleging that the addresses identified by Platypus are linked to the account.

“I’ve traced addresses back to your account from the @Platypusdefi exploit and I am in touch with their team and exchanges. We’d like to negotiate returning of the funds before we engage with law enforcement,” said ZachXBT.

Platypus’ official Twitter account has also retweeted the message from ZachXBT

Eisenberg said shortly after the exploit that he believed “all of our actions were legal open market actions, using the protocol as designed.” Eisenberg was arrested on fraud charges នៅលើធ្នូ 28 ។
