Author Information / Description
This is a simple firefox password stealer that sends the decrypted data from Firefox's signons2.txt to an email account and/or ftp server.

The email sending is mostly untested and considered to be in beta (works with gmail for sure, probably not hotmail though).
To eliminate the need for an smtp server, the Ju u server will preform an MX lookup to find the appropriate MX server for your email address.
Emails often get sent to the junkmail folder, so check that.

The server DOES NOT install itself in any way so it is safe to test on your own.

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.
