Goldun.LC is a password stealer type Trojan that obtains the access data and passwords to the e-gold account of the affected user. In order to do so, it installs itself as BHO (Browser Helper Object) in Internet Explorer.
Whenever this web browser is run, the Trojan will activate and log the keystrokes entered by the user in the e-gold.com website so that it captures the username and password of the user's e-gold account. Then, the Trojan sends the gathered information to a remote computer through a TCP port.
Goldun.LC 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.
However, it usually reaches the computer in an email message, as an attachment with the same icon as a BMP image.
