Definition ∞ API injection involves introducing unauthorized commands or data into an application programming interface call. This technique exploits vulnerabilities in how an API processes input, potentially leading to unintended execution or data exposure. Attackers can manipulate API requests to bypass security controls, gain elevated privileges, or access sensitive information within connected systems. Such exploits are a significant threat to digital service providers and users of blockchain applications.
Context ∞ API injection attacks are a persistent security issue in the digital asset space, frequently impacting decentralized finance (DeFi) protocols and cryptocurrency trading platforms. Recent news often highlights incidents where flawed API implementations allowed attackers to drain liquidity pools or compromise user accounts. The industry continually seeks robust validation and authentication practices to mitigate these risks and maintain user trust.
