Attack Vector

Definition ∞ An attack vector is a pathway or method by which malicious actors can gain unauthorized access to a system or digital asset. It represents a specific vulnerability that can be exploited to compromise security. Understanding these vectors is crucial for assessing the security posture of blockchain networks and decentralized applications.
Context ∞ The ongoing evolution of decentralized finance protocols and smart contract architectures continually introduces novel attack vectors. Security researchers and developers are constantly working to identify and mitigate these potential entry points to protect user funds and network integrity. News reports often detail incidents stemming from previously unaddressed or newly discovered attack vectors.
