Cyber Threat emerges from PDF files

Most internet users are familiar with PDF files and the role they play in delivering essential documents in a transferable and readable format across various devices, such as smartphones and computers. Whether it’s a telecom bill, an image, or even a video file, PDFs are a popular choice for sharing information.

Adobe, the company behind the Portable Document Format (PDF), has analyzed that more than 400 million users access PDF documents, and over 16 billion users prefer to open and edit digital documents online.

However, the widespread use of PDFs has also caught the attention of cybercriminals, who have developed malicious methods to inject malware into PDF files to target unsuspecting users.

A recent analysis by Check Point Software Technologies revealed that nearly half of all email-based cyberattacks last year involved malicious content in PDF form. These attacks often include harmful links, malicious code, and other forms of malware embedded in PDF files and spread to millions of users.

The use of bulk emails makes these attacks particularly effective, with current estimates suggesting that around 12% of such emails result in successful malware distribution. However, as technology companies enhance their security measures and employ automated content filtering, this success rate is expected to decline.

How to Protect Yourself from PDF-Based Email Cyberattacks

Fortunately, protecting yourself from these threats is simple by following a few basic cybersecurity practices:

Be Cautious with Unknown Emails: Avoid clicking on links or downloading attachments from emails sent by unfamiliar or suspicious sources.

Beware of Phishing Tactics: Cybercriminals often use phishing strategies to trick users into clicking on harmful links in emails. Always double-check the sender’s details and be cautious when interacting with unsolicited messages.

Download Apps from Trusted Sources: Ensure that you only download mobile applications from reliable platforms like the Google Play Store, Apple App Store, or Microsoft Store.

Install Anti-Malware Software: Use an effective anti-malware solution on your devices to receive alerts about potential threats, especially when you click on links in suspicious emails or visit dubious websites.

By staying vigilant and following these precautions, you can significantly reduce your risk of falling victim to email-based PDF malware attacks.
