Learn how to hack a PC or remote system using Trojan & Backdoor: Download LOST DOOR RAT all versions here for free

Lost Door is a backdoor trojan horse family of more than 10 variants which can infect Windows operating systems from 95 to XP. It was created by OussamiO and built using Visual Basic. It uses the typical server, server builder, and client backdoor program configuration to allow a remote user, who uses client, to execute arbitrary code on the compromised machine (which runs the server whose behavior can be controlled by the server editor). The server component (75,053 bytes) when running, connects to a predefined IP address on TCP port 2185, awaiting commands from the remote user who uses the client component can execute arbitrary code at will on the compromised machine.

Lost Door allows many malicious actions on the victim’s machine. Some of its abilities include:
  • Reverse connection

Infection Method
Lost Door has a server creator with features that allow it to be undetected by antivirus and firewall software, and also allow it to stealthily run in the background. The software only runs completely (including rootkit) in Windows XP/2000. Such features include disabling security software, removing and disabling system restore points, and displaying a fake error message to mislead the victim.


This version is now detectable by ESET NOD32 Antivirus. For other AV’s, I have not checked.
