The Trojan server runs on the target computer listening for instructions being sent by a remote client and carries out the required actions. When first run a message box is displayed with the text "Error", the Trojan copies itself to a new sub folder of the Windows folder named ActiveXExe\ using a randomly generated filename and to the Windows FONTS folder with the hidden and System attributes set using the name of a system process with an extension of EXE, typically lsass.exe or lsass?.exe where ? is a random character. 

PRORAT:  ProRat is a Microsoft Windows based backdoor trojan, more commonly known as a Remote Administration Tool. As with other trojans it uses a client and server. ProRat opens a port on the computer which allows the client to perform numerous operations on the server (the machine being controlled). ProRat is available in a free version, and a paid version. In the free version, ProRat cannot connect to users over wide area networks (WANs), only over LANs (Local Area Networks). ProRat is known for its server to be almost impossible to remove without up-to-date antivirus software.
