To summarize into some napkin math
The attacker needs to find at least 10 times it's collateral as liquidatable CDPs
To offer the highest premium and not get liquidated they have to offer the highest cut to the relayer (I assume 80%), this means they have to find 50 times their collateral as collateral at risk
This is very unlikely and in this scenario liquidations should be happening due to the sheer amount of leverage
