I am not familiar with crypto and barely understood half of the terms in the article, but shouldn't the buyer confirm again the trade if the price changes? I understand it works like this: V = victim/sandwich bot, S = Salmonella guy, X = asset (Salmonella token?). S -- purchase intent -> X ($5) V detects the intent, purchases X for $5, X price increases to $6 Now it was expected that S would still buy X at $6 (would have this normally be done automatically without confirming the increased price?). But S never pays money for X, so the ETH is now in the hands of the original Salmonella token owner (S) and the attacker is stuck with a worthless token?
