Server:
c:\WINDOWS\nwc.exe 

size: 25.090 bytes 

startup:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run "nwc.exe"

What's New in 1.2:

-Server will read an ip inside a text file on a 
 webhost.
  - replace ip with "uninstall", minus quotes, in
    the text, and it will uninstall the server

-Does not do a system wide hook. Only injects into
 explorer and default browser.

 Fixes:

-Removes files and registry settings with out having
 to reboot.

-webcam detection.

-default browsers, besides ie, work with out popping 
 up or creating many instances of itself. 

-editor always generates server to the current folder. 
(used to generate to random path after first creation)

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.
