#Security Alert: Understanding the $8.5 Million WOOFi Exploit On Mar 5th, WOOFi encountered a devastating flash loan attack on the Arbitrum network, resulting in loss of $8.5 million. Here's a breakdown of what happened & how you can prevent it : techfund.jp/media/WOOFi-Ha…

A few hours ago, a @minerercx exploited a vulnerability resulting in a loss of $456k. The vulnerability lies in the `_update` function. If a user transfers tokens to themselves within the same transaction, there is indeed a potential for their balance to double. This scenario arises because the `_update` function utilizes cached balance values for the sender (`from`) and recipient (`to`). When a user transfers tokens to themselves, the balance update process might not accurately reflect the change. Here's how this scenario unfolds: 1. The `_update` function is called with `from` and `to` being the same address. 2. It retrieves the cached balance for that address before the transfer. 3. It subtracts the `value` from the cached balance for the sender (`from`) and adds the `value` to the cached balance for the recipient (`to`), which is the same address. 4. The balances are updated using the cached values, potentially resulting in a doubled balance for that address. The total fund loss for the miner is almost $456k. etherscan.io/tx/0x5cc93e9d5… is the breakdown of the transaction.

🚨 Security Alert 🚨 @GAMEEToken has experienced a security breach! Unauthorized deployer key access led to an attack using the recoverERC721s() function, bypassing $GMEE recovery protection. Approximately 600m $GMEE has been drained from the contract. 🔗 Attack transactions: 1️⃣ polygonscan.com/tx/0x70f7e0376… 2️⃣ polygonscan.com/tx/0x2340cfdec… ⚠️ Important: The $GMEE's _transferFrom() implementation skips the allowance check, allowing the attacker to use transferFrom() without pre-approval. Exercise caution with OpenZeppelin's ERC20.transferFrom() function. Stay vigilant and follow @GAMEEToken and @prism_blocks for updates on the ongoing investigation and steps being taken to secure the platform. join our telegram community -t.me/+kyzfNY_dRN9hN… #SecurityAlert #CryptoNews #GAMEEToken #BlockchainSecurity #prism_blocks
