PNetwork bridge drains over $4.3 million in tokens that it had issued on its bridge

According to on-chain analysis by security firm BlockSec, the “white hat” exploit was carried out today after the team claimed to have discovered a “misconfiguration” in the token’s smart contract. The pNetwork developers attempted to outrun any malicious hackers by “draining” pgala tokens stored in PancakeSwap pools. These pNetwork-issued tokens are a 1:1 tokenized version of the gala tokens used in the play-to-earn project Gala Games. The tokens are issued whenever users bridge gala tokens from Ethereum’s original chain to the BNB Chain using the pNetwork bridge. Anyone can use pNetwork to lock their assets as collateral in the bridge

A hacker stole around $300,000 in OHM tokens from DeFi protocol Olympus DAO

A hacker stole 30,437 OHM tokens (about $300,000) from one of Olympus DAO’s Ethereum smart contracts.

The contract in question, known as “BondFixedExpiryTeller,” was used to open bonds denominated in Olympus DAO’s OHM tokens. The contract lacked a validation input in the “redeem() method,” allowing the attacker to redeem funds by tricking input values, according to PeckShield. The Olympus team confirmed the exploit in the official Discord and stated: “This morning, an exploit occurred through which the attacker was
