A self-liquidation attack is a malicious strategy where an attacker intentionally causes their own collateralized loan on a decentralized finance (DeFi) protocol to be liquidated. This is done to exploit a vulnerability in the liquidation mechanism, often involving flash loans or oracle manipulation, to profit from the forced sale of their collateral or to disrupt the protocol. The attacker triggers a liquidation under manipulated conditions. It represents a sophisticated form of economic exploit.
