Malicious OAuth integrations grant access without credentials
Attackers abuse OAuth flows to gain persistent access to business-critical SaaS apps. The attack happens inside the browser, during a legitimate authorization flow.

OAuth is designed to let users connect apps without sharing credentials. Attackers take advantage of that trust. Instead of stealing a password, they trick the user into granting access to a malicious or controlled application.
These attacks are commonly delivered through consent phishing or device code phishing. The user never enters credentials into a fake page, and may not enter them at all. In 2025, a single, massive campaign resulted in 1.5 billion records stolen.
OAuth attacks follow legitimate authentication flows. The user interacts with a real login or authorization page, and the application being connected may appear trustworthy. From the identity provider’s perspective, everything looks valid. The user granted access, and no credentials were stolen.
There are no malicious domains to block, no suspicious login attempts, and often no MFA prompt to evaluate. The attack succeeds through user consent alone. Logs show a normal authorization event, not an intrusion.
The critical moment happens inside the browser, when the user approves the OAuth request. That decision, and the context around it, is invisible to most security tools.
Push operates inside the browser, where OAuth authorization flows occur. It provides visibility into when users are connecting applications, what permissions are being requested, and whether those requests introduce risk.
Push can identify suspicious or high-risk OAuth activity in real time and guide users before they grant access. If a user attempts to authorize an app with excessive or unusual permissions, Push can intervene directly in the browser.
Push also gives security teams visibility into existing integrations, helping them identify risky connections and remove them before they are abused. By monitoring OAuth activity at the point of interaction, Push allows defenders to catch these attacks at the moment they happen.
