Noos Virus – How Did I Get It and What Does It Do?

The infection files of Noos virus could hide in files on many low reputation websites, such as torrent and adult sites. These files can often pretend to be legitimate to trick you into downloading and running them. The most often types of files that are mimicked by viruses can be:

Software setups.
Online game patches.
Cracks.
Key generators.

Furthermore, virus files that infect with Noos ransomware can also be sent to victims via e-mail. There, they may be .PDF or .DOCX type of files, that infect computers after being opened. Such infection is done via malicious macros. When sent, the virus documents seem as if they are important invoices or other forms of vital documents.

When your computer gets infected by this version of STOP ransomware, the virus may drop several module virus files in the following system directories of Windows:

%AppData%
%Local%
%LocalLow%%
%Temp%
%Roaming%

Among the files dropped by Noos is also its ransom note, called _readme.txt. The note contains the extortionists’ message, which asks victims to contact the crooks for negotiating ransom price:

The Noos virus variant of STOP Ransomware may also modify the following registry keys in Windows:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Tampering with those keys allows Noos virus to run automatically when Windows starts.

Not only this, but also the Noos virus can run Windows Command Prompt as an administrator and execute the following commands:

→ sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

These commands may ensure that all of the backups on your infected computer plus shadow copies are deleted permanently from your drive.

This variant of STOP Ransomware aims to encrypt files via the AES encryption algorithm by scanning for and replacing the file structure of most of the following file types below:

→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRF Encoded Files .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJ R.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG”

When the Noos virus encrypts files, it uses two types of keys – online or offline. If the key used with your infection is offline, then you have a significantly higher chance at getting your files back. The files are also appended the .noos extension and they are stripped out of their icon. They cannot be opened, unless you have the decryption key. This is why, it is strongly recommended to not try to modify the files directly, because you can break them indefinitely. Instead, we recommend that you back them up on another drive or computer and keep reading the removal and recovery steps below.
