Mal/Jadtre-C is a malware threat and dropper of the Chinese bootkit Guntior. Mal/Jadtre-C has two execution branches; one is a dynamic link library (DLL) and the other is an executable. Throughout its execution down the '.exe' path Mal/Jadtre-C maintains a log file in the %Temp% directory called 'stinst.log' to grab information such as the OS version and its randomly generated name when it copies itself to the system32 directory. Mal/Jadtre-C also makes sure that the %Temp% directory is attached to the PATH environment variable. Mal/Jadtre-C relies on the system time as a seed to create random names for itself and its dropped components. Mal/Jadtre-C also names a copy of itself 'msimg32.dll' in the %Temp% directory, creates a copy of 'HelpCtr.exe' in the %TEMP% directory, and alters the PEFlags in the new copy of 'msimg32.dll' so that they indicate that the file is a dll. 'HelpCtr.exe' is a legitimate and safe Windows file that imports calls from 'msimg32.dll', which is usually found in the system folder. 'HelpCtr.exe' starts the Windows Help and Support Center homepage.
