TROJAN BackConstruction Connection
This signature detects outbound TCP connections that are using a local FTP server installed on ports 5400, 5401 and 5402. 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.
Extended Description
A remote attacker could take control of the system.
