A Remote Administration Tool is a special kind of hacker spyware, used for remote access and control of other people’s computers. The attacker infects the PC via the e-mail or File and Print Sharing. A "server" allows him to connect via a "client" on his own machine. The functions of a RAT may vary, depending on the needs of the hacker. Some RATs can’t really harm your PC and the only purpose they were made for is hooliganism. But some versions can steal vital information, delete files and even crash your system. This RAT was created by a hacker called Karia in May 2002. The programming language is Visual Basic. From the publisher: "Last One Didnt Work...Fixed in This Version Also Made a Un-installer for when u test it on urself ( has to be same dir as the vxd :p ) This Adds A Registry Key That Loads a Specific EXE Name to Run On Startup By Services Process You Can Change The EXE Name TO Whatever you want but be sure to change the .vxd file to the same name. Ex/ RUNDLL32.EXE --- > NewName1.exe RUNDLL32.VXD --- > NewName1.vxd Simple Eh?? Just Edit the .vxd file to the Exe Name Of Your Choice ( Must be in the same Directory ) it Also Executes the EXE File As Well"
