.Onyon Ransomware – Update
.Onyon Virus – Spread
The .Onyon file virus could spread its infection via various methods. One of these methods is seen as the main one for spreading it, which is with a payload file that executes the malicious script for the ransomware, which in turn infects your computer system. Such payload files can be seen distributed around the Internet and you can see examples being detected by many security vendors as showcased right here:
.Onyon file virus could spread its payload file on social media sites and file-sharing networks. Freeware applications which are found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Avoid opening files straight away after you have downloaded them. That stands especially for ones that came from sources like suspicious e-mails or links. What you should rather do is to scan files before opening them with a security tool, while also checking their size and signatures for anything dubious. Also, you should read the ransomware prevention tips given in the forum section.
.Onyon Virus – Details
The .Onyon file virus takes its name from the .Onyon extension that it appends to all files which it encrypts. Malware researchers have found that it is a variant of the the .BTCWare File Ransomware Virus.
The .Onyon file virus could make entries in the Windows Registry to achieve persistence, launch and repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each boot of the Windows Operating System, and one such entry is outlined down below:
The ransom note will be placed inside your personal computer after the encryption process is complete. The note is written in English, but that doesn’t mean that the main aim of the virus is the English-speaking user. Inside, you will view the payment instructions for restoring your files. The ransom note is written in a file called “!#_DECRYPT_#!.inf”.
The !#_DECRYPT_#!.inf file will show the following ransom note:
That ransom note reads the following:
All your files have been encrypted due to a security problem with your PC.

The developers of the OnyonLock ransomware are using the ProtonMail encrypted email service for one of their samples as it can be seen from the note above. Different malware researchers detect the following two e-mail addresses to be used by OnyonLock:
Instructions presented in the ransom note of the .Onyon file virus should not be followed. You should NOT under any circumstances write to the cybercriminals. Nobody could give you a guarantee that your files will get restored if you pay the ransom. However, you could try to get 3 of your files decrypted, if at a later date a free decryptor is distributed.
.Onyon Virus – Encryption
The .Onyon file virus ransomware is spotted to encrypt files that have the following extensions:
→.exe, .cab, .xml, .dll
However, it is not excluded for the ransomware to target the extensions of its previous variant, which are:
→.1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw, .css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf, .gif, .htm, .html, .indd, .iso, .jpe, .jpeg, .jpg, .kdc, .lnk, .mdb, .mdf, .mef, .mk, .mp3, .mp4, .mrw, .nef, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .pfx, .php, .png, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .r3d, .rar, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srw, .tif, .wb2, .wma, .wpd, .wps, .x3f, .xlk, .xls, .xlsb, .xlsm, .xlsx, .zip
Each file that gets encrypted will receive the .Onyon extension appended to itself. Some malware researchers say that the algorithm being used for the encryption process is AES but that has not yet been confirmed.
The .Onyon file virus will erase the Shadow Volume Copies from the Windows operating system. That will make the encryption process more viable since it will eliminate one way for a possible file restoration. Keep on reading to see what ways you can try out to potentially recover some of your data.
