A significant backdoor in enterprise security involves persistent OAuth tokens granted to third-party apps, which do not expire, reset, or receive automatic monitoring, allowing attackers to bypass traditional defenses like MFA once compromised. Research shows 80% of security leaders recognize the risk, yet many do not actively monitor these tokens, exemplified by the Drift-Salesloft attack where stolen OAuth tokens were exploited to access data across hundreds of organizations. Effective security demands continuous behavioral monitoring of apps, blast radius assessment, and intelligent responses to mitigate risks posed by legitimate apps whose credentials have been weaponized after installation.
