The attacker then swapped 500 ETH to 1.7k INV so that it went through the INV-WETH pair on SushiSwap, significantly changing the price due to low liquidity, i.e., 50x.

At the same time, the attacker started spamming transactions with an exploit to be the first to get into the next block and get an inflated price from SushiSwap. Attackers used multiple addresses and additional contracts to confuse generalized bots, which could front-run the attacker.
