Banbra.GKB is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions. Banbra.GKB is designed to affect one or more specific companies. 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 sends the gathered information to a remote user by any available means: email, FTP, etc. It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level. Banbra.GKB 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.GKB 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. |
