Remove Nemucod Ransomware and Restore .Crypted Encrypted Files

decrypt-text.sensorstechforumA new javascript type of ransomware has been reported to infect users globally. This crypto malware is particularly devastating because it uses an immensely strong cypher to encrypt the files of affected users, making them impossible to decrypt directly even if a very powerful system is used. Nemucod also demands a ransom payment in BTC from affected users which equals to approximately 200 USD. The good news is that Emsisoft researchers have discovered a decryptor and we strongly advise following the step-by-step removal instructions below to remove Nemucod Ransomware and unlock your files.

Nemucod Ransomware – Distribution

To infect computers, Nemucod may use spam e-mails to redirect users to either website that automatically download and execute a malicious payload carrying file or an infected e-mail attachment. Here is an example of such spam e-mail:

spam-email-sensorstechforum

The infected attachments are usually Micorosoft Office documents or Adobe Reader .PDF files with infected macros. As soon as the macro has been enabled, Nemucod may execute a malicious script that drops its payload.

Nemucod Ransomware In Detail

Symantec researchers report that once activated on the computer; the malicious JavaScript may drop the following modules of Nemucod in several key Windows locations:

In %Temp%
a0.exe
a1.exe
a2.exe
a.txt
On %Desktop% of the User’s Profile
DECRYPT.txt

Nemucod ransomware may also create registry entries to set the malicious executables to run everytime Windows boots up. The keys that are reported are the following:

In HKEY_CLASSES_ROOT
Crypted\shell\open\command\”(Default)”=notepad.exe “%Temp%\a.txt”
.crypted\”(Default)”=Crypted
In HKEY_CURRENT_USER
SOFTWARE\Microsoft\Windows\CurrentVersion\Run\”Crypted”=%Temp%\a.txt

These keys are specifically created to run the ransom note (“a.txt”) every time Windows starts.

Nemucod encrypts the most widely used file types. To do this, it uses an escalated command In Windows command prompt. The command for encryption is reported by researchers to be the following:

→ For (var I = 67; I <= 90; i++) { Fp.WriteLine(“dor /B “ + cq + String.fromcharCode(i) + “:” + cs + cq + “ && for /r” + cq + String.fromCharCode(i) + “:” + cs + cq + “ %%i in ( file extensions which Nemucod encrypts ) do (REN “ + cq + “%%i” + cq + “%%i” + cq + “ “ + cq + “%%~nxi.crypted” + cq + “&call “ + fn + “.exe” + cq + “%%i.crypted” + cq + “)”); };

The command creates a call to action for the encryption module of the ransomware. After it, the malware starts looking for files of the following types:

→ .zip .rar .7z .tar .gz .xls .xlsx .doc .docx .pdf .rtf .ppt .pptx .sxi .odm .odt .mpp .ssh .pub .gpg .pgp .kdb .kdbx .als .aup .cpr .npr .cpp .bas .asm .cs .php .pas .vb .vcproj .vbproj .mdb .accdb .mdf .odb .wdb .csv .tsv .psd .eps .cdr .cpt .indd .dwg .max .skp .scad .cad .3ds .blend .lwo .lws .mb .slddrw .sldasm .sldprt .u3d .jpg .tiff .tif .raw .avi .mpg .mp4 .m4v .mpeg .mpe .wmf .wmv .veg .vdi .vmdk .vhd .dsk Source:Symantec

The files encrypted are not fully encoded, instead only a part of them is cyphered (usually 32 or 64 bits of the file), which is more than enough to make them corrupt. Then, the ransomware appends, the .crypted file extension to them. The encrypted files look like the following:

  • New Text Document.txt.crypted

Furthermore, regarding file encryption, the Trojan is believed to use modules from 7zip which it may download via connecting to its command and control domains. The C&C servers of the cyber-criminals are reported to be the following:

  • Ujjwaljeweller(.)com
  • Topikriau(.)com
  • yc4tuna(.)com
  • yingyigoo(.)com
  • xn--oi2bq3ygphw3bbzh(.)com

After encrypting the data, Nemucod executes its ransom note for the affected user to see. The notification is reported to be the following:

→ “ATTENTION!
All your documents, photos, databases and other important personal files were encrypted using strong RSA-1024 algorithm with a unique key.
To restore your files you have to pay 0.52985 BTC(bitcoins).
Please follow this manual:
