How to remove Satana virus (Removal Guide)
Satana virus is a term used to identify ransomware that that encrypts the files on the computers it infects and append them with a new file extension. The file extension that is added to files encrypted by this virus will vary per each infected person. The virus will add an email address and then three underscores to the filename. There are several different email addresses used so it will change for different victims. For example, test.png could become Sarah_G@ausi.com___test.png or Gricakova@techemail.com___test.png.
The Satana virus will also add a ransom note titled !satana!.txt in each folder that it infects files in. The !satana!.txt file starts off by saying “You had bad luck. There was crypting of all your files in a FS bootkit virus <!SATANA!>” and further contains additional information and instructions how to decrypt your files by paying a ransom and obtaining a special key.
To make matters much worse, the ransomware will install a bootlocker to prevent you from logging into Windows. The bootlocker installed by the ransomware will display immediately before Windows starts and require a password before it will allow a victim to start Windows. The Satana Ransomware requires .5 bitcoins in order to get the decryption key.
When Satana ransomware is initially contracted it will scan all local drives and unmapped network shares for certain file types and encrypt then. The targeted file types are:
.bak, .doc, .jpg, .jpe, .txt, .tex, .dbf, .db, .xls, .cry, .xml, .vsd, .pdf, .csv, .bmp, .tif, .1cd, .tax, .gif, .gbr, .png, .mdb, .mdf, .sdf, .dwg, .dxf, .dgn, .stl, .gho, .v2i, .3ds, .ma, .ppt, .acc, .vpd, .odt, .ods, .rar, .zip, .7z, .cpp, .pas, .asm,
Once this si complete it will then add a new file extension to the files it infects. It will append an email address and then three underscores to the filename. The inserted email address is specific to the victim. The virus claims that the victim must contact the specific email address after making payment in order to retrieve the decryption key. The email addresses that I have seen associated with this ransomware are:
Gricakova@techemail.com email@example.com Sarah_G@ausi.com firstname.lastname@example.org email@example.com firstname.lastname@example.org
Satana ransomware is usually spread via malicious browser attachments inside email messages. It can also be spread by compromised websites that host malware and malicious social media posts.
As you can see this is a very serious computer infection. It is not recommended to make a payment to the malware author unless you have no choice. Unfortunately, at this time there is no way to decrypt Satana encrypted files for free. If anything is discovered, it will be posted on this webpage so bookmark it for future reference.
