FBI Warns: Malware Hidden in File Conversion Tools*

Recently, the FBI warned about an emerging threat involving cybercriminals embedding malware into file conversion tools. Whether you are converting documents, spreadsheets, or media files, these seemingly innocent free utilities available online may be putting your personal and corporate information at risk.

The FBI’s Denver Field Office reported that attackers are disguising malware within online and downloadable file conversion tools. Once executed, these malicious programs can grant unauthorized access to sensitive information, including:

  • Email addresses
  • Passwords
  • Social security numbers
  • Cryptocurrency details

In some cases, the malware has led to identity theft or ransomware attacks, which can have significant consequences for individuals and organizations.

How to Protect Yourself

We all must remain vigilant. To minimize risk, follow these best practices:

Use only approved file conversion tools vetted by your IT department.
Verify that any online service you use is secure—look for HTTPS and reputable sources.
Keep antivirus software and operating systems updated to defend against evolving threats.

Security Is a Shared Responsibility

Even a compromised device can have far-reaching implications. If you encounter suspicious websites, applications, or unusual system behaviour, report it immediately to your IT security team.

Stay informed. Stay secure.
