INTRODUCTION

-CS 1.8 is a Telnet-based trojan; it means that you don't need any client to connect,
you just use your favourite terminal.

TECHINICAL INFO

-it's written in VB6 and uses winsock, so if you get an error running the file, you
can find the runtimes on the site(most of the people have these files)
-the server listens on PORT 200 for a connection, therefore set the remote port in your
terminal to 200.
-it has a total of about 47 commands; to see a list of the commands, type "help", and to see what a
command does,  type "help command" (without the quotation marks); it's very simple to use...
-the commands are listed alphabetically, so you can find what you need quicker
-no need to list the commands here, you'll see them when you type help...
-the size of the server should be 53,8KB, you can rename it to anything you want,
just leave a exe extension.
-it supports multiple clients

TIP

-when connecting to someone, first thing you should do is get the passwords, by typing "passwords".

Ghirai

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.
