it changes the security settings of Internet Explorer, decreasing its security level; it listens on open ports in order to control the computer remotely; it awaits remote-control orders received through
other channels; it changes system permissions, decreasing the security level. Hupigon.AKT prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.). 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.
- It injects itself in running processes.
Hupigon.AKT does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc. |
