Authorization Sprawl: The Vulnerability Reshaping Modern Attacks


Posted on by Joshua Wright

Authorization sprawl is rapidly becoming one of the most exploited vulnerabilities in modern enterprises. As organizations adopt SSO, PATs, cloud integrations, and federated identity, attackers are finding new ways to move laterally and access sensitive systems without triggering traditional security alerts. Groups such as Scattered Spider, LAPSUS$, and ShinyHunters are already using these techniques to devastating effect, bypassing strong authentication, EDR, and network monitoring controls. This white paper explains how:

  • Authorization sprawl works
  • Why existing defenses fail
  • What organizations must do to reduce risk and respond effectively

What You Will Learn

  • Why authorization sprawl has emerged as a new vulnerability class that attackers exploit across SaaS, cloud, and on-premises systems.
  • How real-world attacks leverage tokens, SSO sessions, and federated identities to bypass even strong authentication and monitoring tools.
  • The limitations of traditional defenses like EDR, impossible travel detection, and remote browser isolation against authorization abuse.
  • Practical defensive measures including, mapping authorization paths, eliminating long-lived tokens, and improving SaaS logging and browser visibility.
  • How to adapt incident response playbooks to address the unique challenges of authorization sprawl.
