More sophisticated than many of its brother backdoor programs, Win32.Masteseq, makes its way onto users’ computers through an exploit in Microsoft’s Java Virtual machine.  Once this parasite has entered, it will drop an executable file into your Windows directory.

Win32.Masteseq also uses a system of DLL ‘plugins’ to perform various functions on your PC.  This would consist of downloading and executing files from the Internet and sending data through the use of a remote script. One of the plugins is entitled kernel32.dll and it is usually 7,582 bytes in size.
