Symbiom Ransomware – In-Depth Overview

Symbiom is a virus that could encrypt your files and extort you to pay a ransom to get them back to normal. Malware researchers have discovered that it is a variant of the HiddenTear open-source project. The ransomware is disguised as a hack tool for the game “Overwatch”.

Symbiom ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows OS. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

That ransom note is inside a file called README_Ransomware_Symbiom.txt. You can preview it from the below screenshot:

The ransom note reads the following:

Your files have been locked by Symbiom!

Send 0.1 bitcoin (It is about 250 dollars) to : 13NjrGWP8GBRSWCgNBPYpPSGUfbyiYGnDc
Afterwards, send your bitcoin address which you payed with to : [email protected]
Don’t worry. I will save your files if you pay.


The note of the Symbiom ransomware states that your files are encrypted. A ransom of 0.1 BitCoin or 250 US dollars is demanded as payment for potentially unlocking your files. However, you should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware viruses or do other criminal activities.

Symbiom Ransomware – Encryption Process

As Symbiom ransomware is a HiddenTear variant it could seek to encrypt files with these extensions:

→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp

Every single file that gets encrypted will become inaccessible and might receive the same extension appended to it, which is .symbiom_ransomware_locked. That extension will be added as a secondary one without modifying the original filename and extension of files. The encryption algorithm which is implemented is undoubtedly AES since it is a variant of the HiddenTear open-source ransomware project.

The Symbiom cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your files.
