What is an Attack Vector? 16 Critical Examples in 2023 | UpGuard

This article defines attack vectors and differentiates them from attack surfaces, then catalogs common vectors including compromised/weak credentials, phishing and social engineering, malware/ransomware, vulnerabilities and zero‑days, misconfigurations, brute force, DDoS, SQL injection, XSS, session hijacking, man‑in‑the‑middle, and third‑/fourth‑party risk. It explains attacker motivations and passive vs. active exploitation patterns, and recommends defenses such as strong authentication (MFA/password managers), encryption, patching and vulnerability management, secure configuration, backups and resilience planning, employee security education, data leak detection, antivirus updates, and vendor risk monitoring, concluding with an overview of UpGuard’s attack surface management capabilities.
