DeFi Hack

Definition ∞ A DeFi hack is an unauthorized exploit of vulnerabilities within a decentralized finance protocol, leading to asset loss. These security incidents often target smart contract code, protocol design flaws, or oracle manipulation. Attackers typically exploit weaknesses to drain liquidity pools, steal user funds, or manipulate asset prices. The immutable nature of blockchain transactions means recovery is frequently challenging or impossible.
Context ∞ DeFi hacks remain a persistent concern, with news reports frequently detailing significant financial losses across various protocols. The ongoing security risks highlight the nascent state of decentralized technology and the necessity for rigorous auditing. Community efforts now concentrate on improving smart contract security and developing robust incident response mechanisms.
