Pass-the-Hash
What is Pass-the-Hash?
Pass-the-Hash is a core system security concept in cybersecurity. It describes techniques, risks, or controls that defenders and ethical hackers must understand to protect systems and conduct authorized security testing. Learning Pass-the-Hash helps you recognize attacks in the wild and apply industry-standard mitigations aligned with frameworks like OWASP and NIST.
Pass-the-Hash sits within System Security and is commonly encountered at the advanced level of security practice. Practitioners study how Pass-the-Hash appears during reconnaissance, exploitation, or defense-in-depth design. On Codelivly, you explore Pass-the-Hash through structured lessons and safe practice environments so you can map theory to hands-on outcomes without risking production systems. Understanding indicators, blast radius, and logging around Pass-the-Hash improves both penetration test reports and blue-team detection engineering.
How it works
Pass-the-Hash typically begins when an attacker identifies a weak input path, misconfiguration, or trust boundary. The technique abuses normal application or network behavior to achieve unintended access, data exposure, or code execution. Defenders detect it through correlated logs, anomaly detection, and hardened configurations.
Prevention
To reduce risk from Pass-the-Hash, apply defense in depth: validate input, enforce least privilege, patch promptly, segment networks, and monitor for known indicators. Regular authorized testing and secure SDLC practices help catch issues before attackers exploit them in production.
