Banbra.BXL is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it notifies the attacker that the computer has been compromised and is ready to be used maliciously; it changes system permissions, decreasing the security level.
Banbra.BXL 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.BXL accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.
Banbra.BXL 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.
