These long-lived credentials represent a silent but catastrophic vulnerability in your cloud infrastructure. This blog explores why long-lived credentials have become the primary attack vector for identity-based breaches, how red teams exploit them during penetration tests, and what you must do today to eliminate this ticking time bomb.
