DCMD:
size: 987 bytes

port: 23 TCP

startup:
none

Compilation:
In order to compile dcmd, NASM (Netwide Assembler) must be installed on your computer. 
NASM is free, open-sourced, and can be found at http://nasm.sf.net. 
It's also recommended that you install NASM on your C:\nasm directory (unless your local drive was something other than that).
To compile, simply run "make.bat". dcmd will spawn a shell on port 23 by default, 
but you can change this value by altering the value for "PORT" (defined at the beginning of the file).
Also, for maximum compatiability, you might want to define "NO_ORDINAL", by removing the ";" (semicolon) from the define.
The downside of this is that the exe will be bumped up to 1004 bytes (for people who care, WSASocketA() is imported by name 
instead of by ordinal, and therefore it will take up more space). Usually, this won't be an issue (i hope...)

Usage:
If you're going to use my code, at least drop me some credits, 
and if i do catch somebody just recompiling this and calling it their own, they will be publically humiliated, and owned by 0days :P
that's about all.

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.
