Cybercriminals are no longer relying on obvious attack vectors. Instead, they’re slipping malware into your inbox disguised as one of the most trusted file formats: PDFs.

According to a recent report, 22% of all email-based cyberattacks now hide malicious payloads inside PDFs, making them one of the most exploited file types in modern phishing campaigns.

It’s not just random spam or suspicious senders – these weaponized PDFs are often embedded in well-crafted emails that appear to come from colleagues, vendors, or trusted partners. The recipient opens the file, unaware that a single click has already compromised their device or granted unauthorized access to sensitive company data.

Why PDF-Based Attacks Are So Effective

  • PDFs bypass traditional antivirus filters by hiding code within scripts, images, or embedded links.
  • Attackers exploit trust – most users don’t hesitate to open a PDF, especially if it appears relevant.
  • These files can silently execute payloads, log keystrokes, or redirect users to malicious domains.

The Stakes Are Higher Than Ever

Once inside your network, these attacks can lead to:

  • Credential theft and privilege escalation
  • Lateral movement across systems
  • Exfiltration of sensitive data
  • Business disruption and reputational damage
