Satana ransomware. !satana!.txt

Satana ransomware is the new Petya relative. Petya and Mischa bundle, was the first ransom attack with two modes. Both modes are applied one after the other, instead used as alternatives. Satana ransomware does exactly the same as Petya and Mischa would do after infecting computer system. Once the system is infiltrated, the executable will disappears and copy of itself in %TEMP% folder hiding behind random name. The first mode of the malware will write malicious code, at the beginning of the harddrive (low-level attack). The second mode, however will encrypt individual files and victims will no longer be able to open them. In order to receive decryption key user will have to pay 0.5 bitcoin (approximately $350). Of course if you don’t have any valuable data a low level format will fix the problem along with reinstall of operating system.

Satana ransomware

It seems that Satana ransomware is at early stage of development and first samples found are more likely experimental. However files will be encrypted one by one and ransom note !satana!.txt will be dropped. File will be renamed with e-mail [email protected] followed with the file name. If user reboots the system bootlocker will prevent from starting windows and display ransom note which you can see above. Emails related with Satana.

In first mode only the master boot record (MBR) is encrypted. Backups will recover the original MBR, allowing the system to boot again. However in the second mode files on the storage device will be encrypted targeting the following extensions:

.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

It seems that Satana ransomware stores the key if there is connection to the C&C. Bad news for users is that Satana can perform encryption offline. If that is the case, key is lost and even if victim pay may not get their files back. It was not expected that this ransomware will be distributed on a large scale, but few days after first discovered distributing is rising.

How to protect against ransomware is most frequently asked questions in the past year. Since ransomware has become the biggest threat among all viruses, people ask themselves if there’s a way to protect from such. It is already too late if you once suffered ransom attack and file has been locked. For some there is a solution but for others disappointment. Either way popularity of ransomware rises and new development are presented every day.

What can we do against the battle with ransomware?

  • If you are already infected do not pay the ransom! Remove the virus and look for other solutions rather than paying. Paying the ransom may be your only option if you have really valuable data. However we do not recommend doing this because you will support the work of criminals. The risk of losing money and still stuck with encrypted files since there is no guarantee in any way that you will recover what one is lost.
  • Security researcher are always working on recovery solutions. Not all ransomware are professionally developed and being cracked, but some are so good developed that there is no current way to be beaten at the current date. One of the solutions is system restore.
  • Best solution si if you have a backup, wipe your hard drive and perform system restore. If not, backup your data frequently. Store backup data in any removable storage device or use any online backup services.
  • Protect your computer with antivirus, internet security, anti-malware software or new developed applications like anti-ransomware. Highly recommended is to keep it up to date and use the paid surveys. We do not recommend free applications.

Now that you have been infected you have a few options:

Many suggest that you simply pay and hope that you will get all off your data back. However in this case you risk losing money and still being stuck with crypted files. We do not recommend this way simply because you will support the work of hackers and the more money thay get the stronger they will become.

The best option for you is if you have a backup, wipe your hard drive and perform system restore.

Use any type of anti malware software to remove Satana ransomware.

NOTE: In this option the virus will be removed but the files will remain locked! You have to decrypt your files.

New research discovery shows how ransomware deletes files and substitute encrypted copy of them. It is not guaranteed, but it is a possibility that you may recover your files with data recovery software. Before trying to decrypt any files you can scan your computer for posible data loss.
