Its kind of a Trojan Proxy. No big deal, it just listens on a pre defined port, 
 and makes a connection to another port. All Data that is transferred will be visible
 in text boxes. You might now ask, so what is it useful for? You can use it to have
 it act as a proxy between a Trojan Client and its Server. That means that you will
 see all the commands that are sent from the client to the Server and vice versa all
 answers from the Server to the Client. This can be used to study the Trojan
 functions or to make a list of the commands the client uses. Most Trojans could be
 used with Telnet as a client if you would know the right commands

This archive is an almost-complete reconstruction of the legendary Mega Security (also known as Kobayashi), a premier 90s-era "Trojan Database" where malware authors once showcased their work. After a decade offline, the site was brought back in August 2024 by its original creator, MasterRat, who authorized the Malware Gallery to host this modernized, searchable version of the collection. While the original site remains available for those seeking a nostalgic, old-school experience, we are proud to continue its legacy here. Full credit and thanks go to MasterRat and the retired Mega Security staff for their years of dedicated work in cataloging these historical samples.
