Similar to the previous version of the ransomware, virus may use several types of tools to spread:

  • Exploit kits.
  • JavaScript of malicious character.
  • Other malware that may have previously infected the victim’s computer.

In addition to this the n1n1n1 ransomware could also use spam campaigns of malicious character that allow the makers of the virus to spread it’s payload by a malicious attachments carrying the tools above in combination with obfuscator that will evade any security software.

N1n1n1 v2 Ransomware – Technical Analysis

When it has infected the computer, the n1n1n1 ransomware connects remotely to a host from where it may download one or more malicious files of the following file types:

.exe, .dll, .bat, .vbs, .tmp

Not only this but the files dropped may be preprogrammed to be located on specific Windows folders and the most often targeted folders are usually the system folders, such as:

%AppData%
%Roaming%
%Local%
%SystemDrive%
%Windows%

N1n1n1 ransomware does not end there with it’s preparation stage. The virus may also heavily modify the Windows registry settings, and this may allow it to run on system startup automatically. This is achievable by either dropping files in the %Startup% folder of Windows or using a malicious script to add value strings in the following Windows registry subkeys:

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

After the virus is running, one way or another, n1n1n1 immediately gets down to encoding files. The encoded files which it targets are usually the usually targeted types of data that is often associated with documents, pictures, videos, images, database files, Microsoft Office documents and even archives and Adobe .pdf files. The encrypted files’ code looks like the image below with an added 999999 file marker to them, according to researcher Michael Gillespie, who researched a sample of the virus:
