Poly Network confirms attack, second DeFi hack on the platform since 2021

Poly Network is the same DeFi platform that gained popularity for being hit by the largest hack in decentralized finance history. In 2021, Poly Network suffered a hack on the Binance Smart Chain, Ethereum and Polygon blockchains.

The team identified three addresses that collectively identified $600 million in different cryptocurrencies, including USD Coin (USDC), Wrapped Bitcoin (WBTC), Wrapped Ether (WETH) and Shiba Inu (SHIB). 

The hack was termed the largest one in DeFi history. Early today Poly Network informed crypto market participants that cybersecurity professionals have been engaged in investigating the recent attack on the platform. 

In the attack on July 2, hackers minted 99,999,184 Binance Coin (BNB), 10 billion Binance USD (BUSD) on Metis; 999.81 Trillion SHIB on Heco , 87,579,118 COW and 999,998,434 OOE, 636,643,868 STACK, 88,640,563 GM and 2,175,053 03 were issued on Polygon, and 378,028,371 STACK, 82,854,568 XTM, 11 ,026,341 SPAY, issued 89,383,712 GM on Avalanche, 8,882,911 METIS, 926,160,132 DOV, 978,102,855 SLD and other assets were issued on Binance Smart Chain (BSC).

Expert commentary on Poly Network exploit

Anatoly Makosov, Core Developer at TON Foundation analyzed the exploit on Poly Network. Makosov told FXStreet,

The exploit on the Poly Network further demonstrates the need to remain in a perpetual state of vigilance. Transfers of values between different blockchains use cross-chain transfer bridges managed by intermediary oracles. This usually provides an acceptable level of bridge security, but there is always a theoretical possibility that oracles can be hacked.

Makosov explains that the security of oracle bridges helps support the DeFi project’s security infrastructure, avoiding such exploits as seen in the Poly Network attack.
