This article aims to shed light on the risks associated with downloading indiscriminate PDF files and provides tips on how to stay safe in the virtual realm.

The Threat Within: Hidden Viruses in PDFs

Cybercriminals and hackers are constantly evolving their tactics to exploit unsuspecting users, and one common method they employ is embedding viruses within PDF files. These hidden threats can take various forms, including:
