⚔️ Attack Methodology

Primary Method: Credential Harvesting

The attacker aims to steal user credentials by mimicking a legitimate login page and prompting the user to enter their email.

Secondary Method: Social Engineering

The phishing email leverages the user's familiarity with Microsoft services to trick them into entering their credentials.

🌐 Infrastructure Indicators of Compromise

🦠 Malicious Files

Main File
WebForms.js (or similar ASP.NET client-side script)
File Size

Functions: WebForm_DoCallback(), WebForm_CallbackComplete(), WebForm_ExecuteCallback(), WebForm_InitCallback(), WebForm_InitCallbackAddField(), __doPostBack()

📊 Attack Flow Diagram

1. Step 1: User lands on spoofed SharePoint/Office 365 document sharing page
2. Step 2: Page loads legitimate-looking UI with Microsoft CDN resources
3. Step 3: WebForm_InitCallback() silently collects all form fields (including password inputs) into __theFormPostCollection
4. Step 4: User interaction (e.g., clicking 'Open Document') triggers __doPostBack() or WebForm_DoCallback()
5. Step 5: Callback function dynamically creates hidden iframe or XMLHttpRequest to submit collected data to server
6. Step 6: WebForm_ExecuteCallback() processes server response (success/error) to maintain illusion of legitimacy
7. Step 7: Credentials are exfiltrated to attacker's server while user is redirected to a 'loading' or error page
