Extract text from Seismic Unix data files (SU)
To convert SU data files to another format, you need Emsisoft Decryptor or other Encoded software.
To convert other file formats to the "Encrypted Malware File" file type, you need software like Emsisoft Decryptor or a similar tool.
A .SU file is an encrypted data file created by the Loptr ransomware. When a computer is infected, the malware targets documents, images, and databases, encrypting their contents and appending the .SU extension to the original filename. Users typically rely on security tools like Malwarebytes to remove the infection and specialized decryption tools to attempt file recovery.
Users desperately need to convert these files back to their original formats to regain access to their personal or business data. However, the current format is highly problematic. It is a proprietary, malicious format that locks data behind strong cryptographic algorithms. Standard software cannot open it, and standard conversion tools are entirely useless because the underlying file structure is completely scrambled.
The best target formats are the original extensions the files had before the infection (such as PDF, DOCX, or JPG). Restoring them requires a specific decryption key rather than a traditional format conversion. During this recovery process, users may face permanent data loss if the initial encryption process corrupted the file data.
This file format is exceptionally difficult to open or convert because standard online converters fail to process cryptographically locked data. Often, only dedicated decryption software with the correct private key can properly read or export the data. Convert.guru provides a practical approach to this challenge. Just drag and drop your file to identify the format, view it, and convert it when possible. Convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your SU file, detects the exact format, and lets you read the text inside.
Users also converted SKP, FBX, STL, JPEG, DEAD, BITMAP, BLANK, MG and RF files.
If you want to convert SU file to MG, RF, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D or STL, you can use Emsisoft Decryptor or similar software from the "Ransomware Encrypted Data" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to SU, try Emsisoft Decryptor or another comparable tool in the "Ransomware Encrypted Data" category.
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 SU converter.
