What is a VVOA file?

VVOA files mostly belong to WinRAR. A VVOA file is not a single standard format but a label used to hide files in different containers. In many cases the file uses the internal structure of a compressed archive (ZIP), which is often encrypted and managed by programs like WinRAR.
Other VVOA files may appear as encrypted images (JPG) used by messaging platforms such as Viber, or as secured documents (PDF) that require Adobe Acrobat Reader DC.
This mixed use allows the same file extension to conceal data with different encoding and encryption techniques. It is common for users to see one VVOA file that may need to be handled as a compressed archive, while another might need to be viewed as an image or a document.
To work with these files, check the file’s header (using a hex editor is one option) to decide if it truly follows a ZIP, JPG, or PDF format. For a ZIP-based encrypted file, renaming the extension to .zip might allow extraction with WinRAR (WinRAR webpage). Likewise, a file with JPG content can be opened with image viewers or messaging apps (Viber webpage) and a PDF-type file with Adobe Acrobat Reader DC (Adobe Acrobat Reader webpage).
FilExt.com note: This approach helps protect file contents and may also be used to disguise malicious elements. Understanding the true container type is essential to open and view the contents correctly.

Programs that open and convert VVOA files:

WinRAR
See the previous paragraphs to learn more about the main application. VVOA files are often referred to as WinRAR compresseds because this type of file is primarily created or used by this software.
VooFix Ransomware
The *.VVOA file extension appears to indicate files that have been encrypted by ransomware. Ransomware is a type of malicious software that encrypts a user's files and demands a ransom for their decryption. The .VVOA extension is likely appended to the original filename after encryption. Therefore, files with this extension can vary in their underlying format, depending on the original file type. For example, a document.docx file encrypted by this ransomware might become document.docx.VVOA. The internal structure of a *.VVOA file would likely consist of the original file data encrypted using a specific algorithm, potentially along with metadata related to the encryption process, such as the encryption key (which is typically held by the attackers). Without the decryption key, retrieving the original files is extremely difficult. This file format is classified as Encrypted Files.

VVOA file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. Our examination of the VVOA files comes to the following conclusion:

VVOA is rarely used as a file extension and is used by different programs with different formats. But the following two file formats are common:

35% of all VVOA files use the popular JPG file format. JPEG is the standard image format for lossy and compressed image data. These files are binary files, so they do not contain text, but only cryptic characters. The files are on average 1 MB in size and range from 130 KB to 4 MB. The file type is relatively new. An example of a file name is IMG_20180601.jpg.vvoa or 20180601.jpg.vvoa.
15% of all VVOA files are based on the popular PDF file format. PDF is short for Portable Document Format, is a file format to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. They consist of illegible, cryptic characters. VVOA files are between 55 KB and 1 MB in size.

All other VVOA files (50%) have no uniform format, the following 5 formats can be found: ZIP. Files like these are sometimes linked to docx, xlsx, songs, best or love. Just click the "Choose your .vvoa file to analyze" button on this page to find out what your VVOA file is.
