About ZEPTO files
A .ZEPTO file is an encrypted data file created by the Zepto ransomware, a notorious variant of the Locky malware family. When a system is infected, the virus targets standard documents, images, and databases, scrambling their internal contents using strong RSA-2048 and AES-128 encryption. The original filename is randomized, and the extension is changed to .zepto.
There is no standard desktop application that can open or edit these files. Users typically encounter them during a cyberattack and urgently seek to convert them back to their original targets like DOCX, JPG, or PDF to recover their data. The extreme disadvantage of this format is that it is fundamentally broken and held hostage; the data is completely inaccessible without the unique private decryption key.
Because the internal data structure is entirely encrypted, standard online converters will always fail to process it. Renaming the file extension back to its original state will not reverse the encryption. This file format is exceptionally difficult to open or convert. Emphasize that often only a dedicated decryption tool or an offline backup can restore the original data.
Convert.Guru analyzes your ZEPTO file, detects the exact format, and lets you read the text inside.
If you want to convert ZEPTO file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use Malwarebytes or similar software from the "Encrypted Data Storage" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to ZEPTO, try Malwarebytes or another comparable tool in the "Encrypted Data Storage" category.
The ZEPTO Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ZEPTO converter.
