Poly-DL v1.0 by r3l4x
=====================
Basically, Poly-DL is a semi polymorphic web downloader 
that is very small. Its based on several different stubs, 
each having a different ammount of empty space throughout
them. When the server is made, that space is filled in
with random characters then packed, thus producing a 
different server every time and a psudo polymorphic 
affect. There is the option to mess up the packed header 
and add junk bytes at the end of the file too. To create 
a greater polymorphic affect, select the 15kb option, 
10kb for a lesser affect, ect. 0 Bytes produces the 
smallest server (1kb!) but has the least ammount of randomness.

Editor made in Visual Basic 6
Stubs made in C++

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.
