Smart Contract Attacks

Definition ∞ Smart Contract Attacks are malicious actions targeting vulnerabilities within the code of smart contracts deployed on blockchain networks. These attacks can result in the unauthorized transfer of digital assets, manipulation of contract logic, or disruption of decentralized application services. They exploit flaws such as reentrancy bugs, integer overflows, or improper access controls.
Context ∞ News coverage frequently details instances of smart contract attacks leading to significant financial losses from decentralized finance (DeFi) protocols and other blockchain-based applications. Debates often focus on the methodologies employed by attackers, the effectiveness of smart contract auditing, and the development of more secure coding practices. The ongoing prevalence of these attacks underscores the critical need for rigorous security measures and robust risk management in the digital asset space.
