Online File Converters Could Infect Your Computer With Malware: FBI
If you’ve ever needed to convert a PDF to a DOC or an image to a different format, you might have used a free online file converter. These tools seem convenient, but the FBI has issued a warning that hackers are using them to spread malware.
Cybercriminals have created fake file converter websites that, instead of simply changing file formats, secretly install harmful software on users’ computers. Once infected, your device could be compromised, leading to data theft, financial loss, or even ransomware attacks, warned FBI.
How Hackers Use Online Converters to Spread Malware?
The FBI Denver Field Office has revealed that cybercriminals use fake file conversion websites as traps. These sites often appear in search results through malicious advertisements. They may function as expected but come with a hidden risk—along with your converted file, they also deliver malware.
Some sites trick users into downloading a tool for file conversion, which is actually malware. Others encourage the installation of a browser extension that spies on browsing activity. Once installed, these malicious programs can steal personal information, including:
- Banking credentials and financial data
- Social Security numbers (SSNs)
- Login details and passwords
- Session tokens that bypass multi-factor authentication (MFA)
Many users don’t realize their computer has been infected until it’s too late. This can lead to identity theft or ransomware attacks that lock users out of their files unless a ransom is paid.
Fake File Converter Websites to Avoid
Security researchers at MalwareBytes Labs have identified several dangerous domains involved in these attacks. These sites have been flagged for phishing, trojans, adware, and riskware. Some of them include:
- Imageconvertors[.]com (Phishing)
- convertitoremp3[.]it (Riskware)
- convertix-api[.]xyz (Trojan)
- convertallfiles[.]com (Adware)
- freejpgtopdfconverter[.]com (Riskware)
Since hackers frequently change domain names, these sites may soon shift to new addresses. However, staying cautious of unknown file conversion sites is essential.
How to Stay Safe from Online File Converter Scams?
The best way to avoid these scams is to think before you click. Instead of using free online converters, check if the software you already have can do the job. Here are some safer alternatives:
- Microsoft Office – Converts Word, Excel, and PowerPoint files.
- Adobe Acrobat – Offers secure PDF conversion.
- OpenOffice – A free and open-source alternative with conversion features.
For images, many built-in programs like Preview (Mac) or Paint (Windows) can handle basic format changes.
Using trusted antivirus software can also protect against malware infections. Good security software will scan downloads and block threats before they reach your computer.
Protect Your Identity and Personal Data
If you accidentally download malware, it could steal sensitive information. To protect yourself, consider using an identity theft protection service. These services monitor your financial data and help you recover if your identity is compromised.
Practicing good cyber hygiene is also key. Here are some tips:
- Never download software from unverified sources.
- Be cautious of online ads promoting free tools.
- Regularly update your antivirus software.
- Use strong, unique passwords for all accounts.
Final Thoughts
Hackers are always looking for easy targets, and free online file converters are their latest trick. The warning from FBI serves as a reminder to stay vigilant. By using secure file conversion methods and keeping your devices protected, you can avoid falling victim to malware and cyber scams.
