Summary
Windows Defender detects and removes this threat.
This threat is a malicious PDF file that uses social engineering to target enterprise users and steal their enterprise domain credentials.
It is usually attached to a spam email that imitates a legitimate email from your IT department. The attachment says the IT department is performing server upgrades and it asks you to enter your domain credentials into a website. These credentials are then stolen by the attacker.
Affected users should reset their domain credentials, and have their workstations and email activity audited for malicious remote access.
Use the following free Microsoft software to detect and remove this threat:
- Microsoft Defender Antivirus for Windows 10 and Windows 8.1, or Microsoft Security Essentials for Windows 7 and Windows Vista
- Microsoft Safety Scanner
You should also run a full scan. A full scan might find hidden malware.
