Data Sources:
DeFiPie (PIE), the lending protocol on the Ethereum and Binance smart chains, was hacked. It is recommended that all liquidity providers extract all liquidity from the application. PIE tokens fell by more than 66% in 24 hours. The attacker used a re-entry attack to over-borrow and lent a portion of valuable assets. Later, the counterfeit currency was used for liquidation operations and took away the mortgaged valuable assets, which led to the DeFiPie agreement not only lent assets, but also lost all mortgage assets, and liquidity was lost. Peckshield confirmed just two hours after the attack that the source of the problem was “evil pTokens [that] allow for nested borrows".
