it listens on open ports in order to control the computer remotely; it awaits remote-control orders received through
IRC. It uses stealth techniques to avoid being detected by the user: - It uses techniques included in its code to hide itself while it is active.
Bagle.JZ uses the following propagation or distribution methods: - Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications.
