Code Injection

Definition ∞ Code injection is a security exploit where malicious code is inserted into a system’s input. This unauthorized code then executes, potentially leading to unauthorized access or data alteration. Such vulnerabilities can affect smart contracts and blockchain applications, posing risks to digital asset integrity. Understanding this threat is vital for assessing the security posture of blockchain protocols and decentralized services.
Context ∞ The discourse surrounding code injection in the crypto space predominantly focuses on its implications for smart contract security audits and the prevention of exploits on decentralized finance (DeFi) platforms. News reports often detail instances where flawed code has been exploited, resulting in significant financial losses. Ongoing efforts concentrate on rigorous code verification, formal verification methods, and secure development practices to mitigate these risks.
