68% of cyberattacks start via email; 22% involve malicious PDFs. With over 400 billion PDFs opened in a year, PDFs serve as effective delivery mechanisms for attacks due to their complexity and perceived safety. Attackers leverage social engineering and advanced evasion techniques, making it hard for security systems to detect threats. Typical PDF attacks include link-based campaigns leading to phishing sites, utilizing benign links and QR codes for obfuscation. Users are advised to verify senders, be cautious with unexpected attachments, and keep software updated to mitigate risks.
