Version v4.0 notes:

Windows XP Compatibility -
The client works perfectly on Windows XP, but
there are still issues on systems running the server under windows XP. 
The older XP servers seem only to work under 'laboratory' (ie. Test) 
conditions. The server is unresponsive when people come to use it.
Most systems report a error with enumerating passwords cache, and 
mpr.dll error. I am working on this, and ill post updates on the site
to keep you up to date with the XP server development.

Windows 2000/ME Compatibility -
The server works fine on 2000 and ME until the server user attempts to 
shutdown the system. The system usually haults at this point.
To allow the machine to shutdown correctly, you will need to remove
the server from the machine (refer to server removal in the help file).

Keylogger updates:
The keylogger should now be case sensitive. The changes where 
completly server-side, so the clients keylogger functions actually 
remain intact (for backward compatibility).

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.
