Security team: profit of about 9 million US dollars, Moola protocol hacker attack brief analysis: October 19 news, according to Beosin EagleEye Web3 security early warning and monitoring platform monitoring, the Moola protocol on Celo was attacked, and the hacker made a profit of about 900 Ten thousand U.S. dollars. The Beosin security team analyzed the incident for the first time, and the results are as follows:

Step 1: The attacker made multiple transactions, using CELO to buy MOO, and the attacker's initial capital (182,000 CELO).

Step 2: The attacker lends CELO using MOO as collateral. According to the common logic of mortgage lending, the attacker mortgages MOO with value a, and can lend CELO with value b.

Step 3: The attacker buys MOO with the loaned CELO, thereby continuing to increase the price of MOO. After each exchange, the price of Moo corresponding to CELO becomes higher.

Step 4: Since the mortgage loan contract will use the real-time price in the transaction pair to judge when lending, the user's previous loan amount has not reached the value b, so the user can continue to lend CELO. By repeating this process, the attacker increases the price of MOO from 0.02 CELO to 0.73 CELO.

Step 5: The attacker has carried out a total of 4 times of mortgage MOO, 10 times of swap (CELO for MOO), and 28 times of borrowing to achieve a profit-making process.

The mortgage lending implementation contract that was attacked this time was not open-sourced. According to the characteristics of the attack, it can be guessed that the attack is a price manipulation attack. As of the time of writing, through Beosin Trace tracking, it was found that the attacker returned about 93.1% of the funds obtained to the Moola Market project party, and donated 500,000 CELO to the impact market. I left a total of 650,000 CELO as a bounty. [2022/10/19 17:32:31]
