TROJAN BackConstruction FTP Port-Open Reply
This signature detects the command string "ftp open" within a TCP packet sent from a local FTP server installed on port 666. This can indicate that BackConstruction, a basic file server Trojan, is in use on the network. Attackers can use a previously installed FTP server to upload/download files.
