Roe Finance, and LendHub exploited. Mcdonald’s and Australian Open Metaverse initiative.
The numerous attacks on blockchain-based projects show that human integrity is declining, and until morale improves, occurrences like this will continue to happen. A recent report by Chainalysis says that the amount of on-chain illegal cryptocurrency transactions has reached an all-time high of $20,1 billion, growing for the second year in a row.
The BRA token on the BSC chain was attacked, allowing the hacker to steal funds valued 819 $WBNB, or nearly $225,000. The vulnerability was caused by a logical flaw in the BRA contract, which permitted the transfer procedure to generate incentives if the caller and receiver were a pair. The exploiter initially took a flash loan of 1,400 $WBNB, before swapping 1,000 $WBNB for 10.5K $BRA tokens. To earn rewards, the acquired $BRA tokens were transferred to the PancakeSwap pair, and then to the BRA contract. After repeating the transfer operations 101 times, the attacker exchanged back 1.675K $WBNB tokens and repaid the flash loan. The profits from the initial transaction were 675 $WBNB tokens, while another attack transaction netted them 144 $WBNB tokens. We have outlined the detailed analysis of the exploit in our blog post here.
Roe Finance was exploited using a price manipulation attack, resulting in a $80,000 loss, caused due to the limited liquidity of the pool. An attacker-controlled address first borrowed $USDC from Balancer and deposited it in the roeUSDC pool. The same address borrowed 2,953,841,283 UNI-V2 from the pool, while leaving debt to the contract creator, and then deposited the borrowed tokens back into the pool. These actions were carried out approximately 49 times, after which the contract address burned 0.295 UNI-V2 and earned 2.96 $WBTC and 51,661 $USDC. They then gave 26,024 USDC to UNI-V2 and invoked the Uniswap V2 sync function, which manipulated the price of the UNI-V2 obtained from the oracle. Then, they borrowed back 5,673,090 $USDC that had been put into the roeUSDC pool earlier, swapped about 0.66 $WBTC for 14,345 $USDC, and repaid the $USDC back to Balancer. The profit from these were 2.29 $WBTC and 39,982 $USDC, roughly amounting to $80,000. We have published a thorough analysis of this attack in one of our blog posts.
According to Beosin, the ACS token was a rug pull in which $10,000 worth of funds was stolen through a backdoor function. The scammer used a contract function to transfer the ACS within the BSC-USD-ACS pair, leading to an imbalance in the K value, and then used a small number of ACS to transfer out a significant quantity of BSC-USD within the pair.
According to QuillAudits, the UF Dao of XDAO was hacked, resulting in the loss of $90,000 USDC. The root cause of the attack is due to a smart contract vulnerability caused by incorrect parameter settings. The attacker bought a public offer of the UF Dao at a 1:1 rate using USDC, and almost all of it was later redeemed in UF Dao. They began by swapping 0.4 BNB for approximately 111.62 USDC, and then used all of the USDC to purchase a public offering in order to gain 111.62 UFT, the LP token of UF Dao, which represents nearly 94.25% of the total shares. These UFT tokens were then burnt to redeem the USDC from the UF Dao using the held shares.
The LendHub on Heco was exploited, in which hackers stole about $6 million worth of assets. The old LendHub contract wasn't deprecated, which allowed an attacker to use collateral on one of the LendHub's contract to get pegged tokens, and then use these pegged tokens to borrow funds on the other contract. Reports reveal that a part of the stolen funds are held at addresses controlled by hacker, while funds worth 1,100 ETH was deposited into Tornado Cash.
