Scan finds an exposed GitHub token that authenticates to Okta and resolves to an Okta SUPER_ADMIN account, so an attacker creates a backdoor user, assigns apps under another user’s email to impersonate them, then leverages misconfigured Salesforce profiles and permission sets to enable account export and steal records including credit card CVVs. The attacker flips S3 bucket policies to make a public S3 bucket, exports an RDS snapshot into S3 and disables keys to download full databases. Detect via alerts for API-created users with elevated roles, unusual app impersonation and rapid excessive object access combined with exposure scans.
