Crash Report Virus

Crash Report Virus
Type: Worm
In the wild: No
Reported Infections: Low
Distribution Potential: Low
Damage Potential: Low to medium
Static file: Yes
File size: 670-750 kb


Method of propagation:
After the worm's file is started, it copies itself with different names to different folders on a local hard drive. The file names can be semi-randomly generated or they can be any of the following:

%CommonPrograms%\startup\crashreport.exe

%ProgramFiles%\bitcomet\crashreport.exe

%ProgramFiles%\bitcomet\plugin_emule\crashreport.exe

%ProgramFiles%\funshion online\funshion\crashreport.exe

%ProgramFiles%\meitu\kankan\crashreport.exe

%ProgramFiles%\pkr\crashreport.exe

%ProgramFiles%\vombashots\crashreport.exe

%ProgramFiles%\wefi\crashreport.exe

%Programs%\startup\crashreport.exe

The worm spreads itself by creating "Autorun .inf" and a ".exe" onto hard drive partitions,including removable media(eg flsh disk, memory card).
It hides the autorun.inf by changing its file attributes

In order to assure it is executed at every system startup, it creates the following registry entries:

[HKLM\Software\Microsoft\Windows\CurrentVersion\Run]
"crash report" = "%Windir%\crashreport.exe"
