Many content creators frequently use online file converter tools to rewrite documents, convert files to PDF, or change image formats for website use. However, the FBI has issued a stern warning about the risks associated with these platforms.
According to the agency, many file converters that rank high on search engine results may be deceptive, often distributing malware to unsuspecting users. Even more concerning, some of these tools are being used to spread ransomware—malicious software that encrypts data and locks users out of their devices until a ransom is paid.
The FBI’s warning follows an increase in reports received by its Denver Field Office, highlighting the growing number of scams linked to free online conversion tools.
These fraudulent sites primarily target users looking to convert documents, redirecting them to scams involving online betting or cryptocurrency investment schemes.
This tactic isn’t entirely new. In the past, cybercriminals leveraged piracy websites to distribute malware by embedding malicious software in pirated movies and software downloads. Now, they have shifted their focus to search engine results, capitalizing on the widespread use of smartphones running Android and iOS. Given the massive user base, even a 25% success rate could translate into substantial financial gains for these attackers.
Infamous ransomware groups like REvil and BlackSuit have previously used similar distribution methods, and experts warn that more cybercriminal gangs may adopt this strategy in the future.
To stay safe, users should be cautious when using free online tools, verify website authenticity, and rely on trusted cybersecurity measures to prevent malware infections.
