Dynamic Finance, NFT Cloud & Friendsies exploit. Warner Bros., OneOf, & Coinbase web3 initiattives.
Web3 has revolutionized the way we conduct online transactions. The trustless and transparent nature of decentralized platforms has piqued the interest of users and investors alike since the advent of blockchain technology. However, as the number of DeFi applications has grown, so has the risk of scams or rug pulls. These scammers use the lack of regulation in the DeFi space, as well as the anonymity provided by blockchain technology, to disappear with funds. As a result, before investing in any DeFi project, investors and users should exercise caution and conduct thorough due diligence to avoid falling victim to a rug pull.
Dynamic Finance was exploited due to insufficient reentrancy protection in the StakingDYNA contract, which caused the protocol to lose 73 BNB, worth approximately $22,400. The deposit function provided the lastProcessAt value in their contract. However, this value was only recorded for the first deposit or stake due to the logic of the code. At timeframe A, the attacker opened a new vault and deposited a small amount of DYNA. At some point in timeframe B, they took out a fairly large flash loan to borrow DYNA and deposited it before redeeming the deposit, getting rewards, and paying back the flash loan. The attacker then withdrew the rewards and capital multiple times, using the redeem function to keep the assets for profits. We have outlined a detailed analysis of the exploit in this blog post.
NFT Cloud was exploited because the staking contract didn't check the staking status of CloudNFT correctly, resulting in the loss of 265 BNB, worth approximately $81,000. The platform works in such a way that users can deposit CloudNFT and claim Cloud tokens as rewards, where one CloudNFT can only be deposited once. However, the staking contract didn't check the staking status of the first deposited token. Therefore, validations for NFT ownership and lockUntil checks are bypassed when only one token is deposited. The attacker deposited only one CloudNFT to bypass this validation and repeated this process multiple times to claim higher rewards.
Hope Finance, a Tomb-fork based in Arbitrum, published a tweet accusing a team member of rugging the project and stealing KYC information. The scammer changed the router address of the TradingHelper contract using a multisig wallet. The stolen funds totaling $1.86 million were bridged to Ethereum via Celer before being deposited into Tornado Cash.
Friendsies, an Ethereum NFT project, announced that all future plans for the project would be paused after raising more than $5.3 million in ETH in last year's mint. Some users who sought information on the news after the announcement discovered that they had been blocked on Twitter. After a short while, Friendsies removed its social media account, leading to a rug pull.
