What is an STONE file?

STONE files mostly belong to Stone Encryptor. STONE files are files that have been altered by encryption or ransomware tools. They usually hide their true format by using common file types internally like JPG, ZIP, PDF, or PNG while carrying the STONE extension.
Usage and Functionality:

some of these files use the JPG format to disguise an encrypted image. These may even be linked to mobile cases, such as a Galaxy S Note encrypted image.

Some STONE files use the ZIP format, acting as compressed archives that have been encrypted. These are related to software like Stone Encryptor and even tools from AxCrypt.

A smaller group uses PDF or PNG formats, which may show up as encrypted documents or images. For instance, encrypted PDF files reference Adobe Acrobat Reader DC (Adobe Reader), although decryption is needed to open them normally.

Handling: If you encounter a STONE file, it is likely a marker used by ransomware to prevent access. Renaming the file or simply trying to open it with a viewer might not work unless the correct decryption tool is provided.
FilExt.com tip: These details point to the fact that the STONE extension is used to obscure the real file type during a ransomware attack, making it harder for users to access their files without proper decryption.
