Identifying ‘Bladabindi’ virus on your computer

Bladabindi virus acts smart when executed. It generally spreads through the ‘autorun’ from the removable devices and unauthorized download files on internet.

This virus tricks you by keeping itself with disguised icon masks that could mislead you into running the program. The list of most common icons it uses for disguising are shown already in previous article.

When run on your computer, the virus copies itself into one of the following locations with a variable name, for example %TEMP%\svhost.exe:
  • C:\Users\<user name>\AppData\Local\Temp – %TEMP%
  • C:\Users\<user name>\AppData\Roaming – %APPDATA%
  • C:\Users\<user name> – %USERPROFILE%
  • C:\ProgramData – %ALLUSERPROFILE%
  • C:\ProgramData – %windir%
The above locations can be accessed through Win+R(Run) by using the common folder variables shown along with them, for example %APPDATA%.

It also copies itself into startup folder to make sure it runs every time when the computer is started. It can be easily identified with a random 32 alpha-numerical name and .exe extension, for example <startup folder>\5cd8f17f4086744065eb0992a09e05a2.exe

To check your startup folders on your computer, go to any of the following locations or simply copy-paste the path and hit enter:
  • C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
  • C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
It also changes the windows registry keys to run itself every time when the PC starts. The registry keys that would be modified are as follows:

In subkey: HKLM\Software\Microsoft\Windows NT\CurrentVersion\Run
Sets value: "<32 random alpha-numeric characters>" for example, "5cd8f17f4086744065eb0992a09e05a2"
With data: "%TEMP%\<variable name>.exe"
In subkey: HKCU\Software\Microsoft\Windows NT\CurrentVersion\Run
Sets value: "<32 random alpha-numeric characters>" for example "5cd8f17f4086744065eb0992a09e05a2"
With data: "%TEMP%\<variable name>.exe

It also runs net.exe to add itself to the firewall exclusion list and bypass the firewall of your computer.
