Banbra.GCQ is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
Banbra.GCQ redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.
Banbra.GCQ accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.
It uses stealth techniques to avoid being detected by the user:
- It modifies system permissions in order to hide itself.
Banbra.GCQ 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.
