Banker.EBQ 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 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; it changes system permissions, decreasing the security level. Banker.EBQ 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. It uses stealth techniques to avoid being detected by the user: - It modifies system permissions in order to hide itself.
It uses several methods in order to avoid detection by antivirus companies: - It terminates its own execution if it detects that a memory dump program is running, such as Procdump.
- It terminates its own execution if it detects that a debugging program is active.
Banker.EBQ 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. |
