Observed phishing campaign leveraging Gmail accounts to deliver emails containing only the password for a supposed “secure” PDF attachment.

Victim flow:

1. Email contains only the password for the attachment
2. Email also includes a PDF attachment
PDF contains a link redirecting to a fake secure document portal
3. User is prompted with Microsoft device login / OAuth-style authentication
4. Credential theft and session hijacking likely follow

Associated IOC domains:

* omegabearings[.]com
* vaisooru[.]com
* roufoka[.]com

Recommend:
• Block domains at DNS/proxy layers
• Hunt for related OAuth/device code login events
• Review Entra ID sign-in logs
• Reset sessions/tokens for impacted users
• Monitor for suspicious consent grants
