How this kind of attack works

The protocol's own rules had a flaw, for example in how rewards, liquidations or swaps were calculated, and the attacker followed those rules to drain funds.

Would a pre-payment check have helped

Needs other controls

Protocol logic flaws call for audits and formal verification.
