Hacks Analysis
Remitano | Amount Lost: $2.7M
On September 14th, the Remitano exploit on the Ethereum Mainnet resulted in a $2.7 million loss. The root cause of the exploit was the compromise of private keys. The attack included two transactions from one of Remitano’s hot wallets named ‘Remitano 2’. The first transaction involved the transfer of 1,359,253 USDT to the attacker’s address, and the second transaction involved the transfer of 208,188 USDC and 104,360 $ANKR tokens. The Remitano team acknowledged the exploit and temporarily suspended the coin deposit and withdrawal system for maintenance and upgrades.

GAMBL Computer | Amount Lost: $815K
On September 4th, the GAMBL Computer exploit on Arbitrum resulted in an $825K loss. The root cause of the exploit was a flaw in GAMBL’s recommendation system. The attacker was able to place ‘ghost’ bets without depositing any funds and collect referral bonuses in $GMBL tokens. On September 6th, the attackers returned 235 ETH of the stolen funds to GAMBL. The $GMBL token has lost 75% in value following the exploit.

DAppSocial | Amount Lost: $16K
On September 2nd, the DAppSocial exploit on the Ethereum Mainnet resulted in $16K due to a logic vulnerability. The attacker’s initially deployed a helper contract, deposited 2 USDT into DAppSocial’s contract, and called the lockTokens() function, setting the lock duration to 0 seconds. Following this, the attacker called the withdrawTokensWithAlt() function to initiate fund withdrawal. The withdrawTokensWithAlt() function determined the withdrawal amount by subtracting a user-controlled balance from the msg.sender’s balance. This vulnerability allowed the attacker to manipulate the user-controlled balance and profit from the exploit.

Rocketswap | Amount Lost: $868K
On August 17th, the Rocketswap exploit on Base chain resulted in a $868K loss. The root cause of this exploit was the compromise of private keys. The Rocketswap team confirmed that they inadvertently shared private keys on the server during the deployment of their launchpad. As a result, the attacker was able to exploit the contract and transfer 472 ETH. The attacker then bridged the funds to Ethereum using the Stargate bridge. The Rocketswap team froze the contracts following the exploit.
