Trojan.PSW.LionDumper is a Trojan horse that tries to steal passwords. 
It adds a new user, who has administrator rights, to the system. 
The Trojan comes disguised as a Windows NT/2000 password dumper utility. 
(A password dumper is a tool that is used by hackers.)
The Trojan functions only if the user who executed it has administrator rights.
It tries to add a new user with the name ISUR_IWAM, add it to Local Administrators group,
and set a default password for it.
(Symantec)

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.
