Exchange Poloniex de Justin Sun sofre enorme hack
- A Sun confirmou que um hacker atacou a Poloniex na sexta-feira e ofereceu uma recompensa 5% de whitehat ao hacker.
- Alguns especialistas em segurança afirmam que o hack pode ter sido causado por chaves privadas comprometidas ou malware.
On-chain data revealed on Friday that hackers have emptied the hot wallets of cryptocurrency exchange Poloniex, resulting in an estimated loss of over $100 million. Prominent blockchain security firms Cyvers and PeckShield detected a possible compromise around 10:55 UTC. Shortly after that, Poloniex claimed that the exchange’s wallet was inaccessible for maintenance. However, Justin Sun, the owner of Poloniex Exchange and crypto investor, later verified the hack on X (formerly Twitter).
De acordo com o tweet
No momento, estamos investigando o incidente de hack da Poloniex. A Poloniex mantém uma posição financeira saudável e reembolsará integralmente os fundos afetados. Além disso, estamos a explorar oportunidades de colaboração com outras bolsas para facilitar a recuperação destes fundos.
Explorador de blockchain Eterscan displays a series of transfers from the “Poloniex 4” wallet to the hacker’s wallet. Some of the transferred assets include stablecoins USDT and TUSD and meme coins SHIB, PEPE, and FLOKI. The hacker also transferred ETH and TRON.
Data from Arkhan Intelligence confirms that the hacker also stole around 288 million TRX, Trons native token, and 865 Bitcoin, increasing the total theft to almost $126 million. Analyzing the hacker’s move, reports observed that once the assets are sent to one of the hacker’s wallets, they are sent to another wallet before being swapped for USDC using MetaMask.
Alguns especialistas em segurança do Twitter afirmam que o hack pode ter sido causado por chaves privadas comprometidas, engenharia social ou malware. Fundada em 2013, a Poloniex está entre as mais antigas bolsas de criptomoedas. O emissor de stablecoins, Circle, adquiriu a bolsa em 2018 e mais tarde a transferiu para vários investidores. Justin Sun adquiriu a bolsa da Poloniex.
A bolsa enfrentou forte concorrência de bolsas importantes, como Binance e Coinbase. De acordo com o CoinMarketCap, a Poloniex movimentou $616 milhões em volume de negócios nas últimas 24 horas; ainda assim, suas reservas públicas não estão acessíveis para visualização.
O hack na bolsa Poloniex é um dos muitos ataques gravado nas últimas semanas. As trocas de criptografia tornaram-se o foco principal de ataques criminosos e cibernéticos. Em setembro, a exchange de criptomoedas HTX sofreu um hack que destruiu cerca de $8 milhões de Ether. Além disso, a exchange sul-coreana Gdac perdeu $13 milhões devido a atividades de hacking em abril.
Sun compartilha atualização sobre Poloniex
Poloniex owner Sun offered a 5% whitehat bounty to the hacker if they returned the funds in the next seven days. Sun threatened to involve law enforcement agencies afterward. Sun later wrote that “the Poloniex team has successfully identified and frozen a portion of the assets associated with the hacker’s addresses. At present, the losses are within manageable limits, and Poloniex’s operating revenue can cover these losses.”
The crypto investor added that “the team has restored Poloniex’s systems, preserved relevant evidence, and in the coming days, we will work diligently to gradually resume deposits and withdrawals on Poloniex, ensuring 100% security.”
Interestingly, Sun’s TRX token saw a huge surge on Friday, showing it was unaffected by the Poloniex hack.
