Why PDFs Are a Prime Target

3. File Sharing and Phishing
When it comes to PDF phishing, file sharing is a common tactic used by cybercriminals. These scams typically involve the attacker sending an email or message that appears to be from a trusted source, such as a colleague or a reputable company, and includes a phishing PDF attachment. The PDF may seem harmless at first glance, but once opened, it can contain malicious links or malware that can compromise the recipient’s computer or steal sensitive information.
It is essential to exercise caution when receiving unexpected PDF attachments, even if they appear from a known sender. Always verify the source of the attachment before opening it, and consider using up-to-date antivirus software to help detect and prevent phishing PDF attempts.
4. Fake CAPTCHA Redirects
One type of phishing attack PDF to be aware of is the fake CAPTCHA redirect. In this type of scam, attackers will send a PDF file that appears to contain a CAPTCHA verification form.

Always be cautious when encountering any unexpected CAPTCHA forms in PDF files and verify the source’s legitimacy before interacting with them.

In this type of scam, scammers set a static image within a PDF file and add a play button overlay.

This tactic preys on users’ curiosity and desire for interactive content, making them more likely to fall victim to the scam. To prevent this type of phishing scam, it is essential to exercise caution when clicking on any play buttons in PDF files and verify the source before interacting with any embedded content.
The rise of PDF phishing scams presents a significant danger in an increasingly digital landscape.
