PDF Phishing Scams Are Evolving—Here’s How to Stay Ahead
Has a suspicious-looking email with a PDF attachment containing a phone number to call “tech support” landed in your inbox recently? If so, you’re likely the target of a new wave of phishing attacks that are more convincing than ever.

As a trusted provider of managed IT services, IT support, and compliance services for manufacturers and small businesses, we help our clients stay ahead of these scams with proactive email threat detection and endpoint security.
What Is Callback Phishing?
Traditional phishing scams often rely on malicious links or attachments. But callback phishing flips the script. You receive a PDF that appears to be from a trusted brand—Microsoft, Adobe, DocuSign—and it urges you to call a support number to resolve a fake issue.
Once you call, you’re connected to a fake customer service rep who sounds professional and helpful. They may ask for sensitive information or guide you through installing malware disguised as a solution.
Why These PDF Scams Are So Dangerous
Unlike typical phishing emails, these PDFs don’t contain malware. Instead, they launch a social engineering attack by exploiting your trust in phone-based support. The danger begins when you dial the number and engage with the scammer.
How to Protect Your Business
- Don’t trust PDF attachments from unknown senders, especially those urging you to call a number.
- Never call support numbers listed in unsolicited emails or documents.
- Verify contact information directly from the company’s official website.
- Train staff to recognize signs of phishing scams and tech support fraud.
- Use endpoint security and email threat detection tools to scan attachments and flag suspicious content.
