Security Virus Alert! New Trojans Attack Online Banking

Updated on December 10, 2009

Very Dangerous

 Nothing worse than being violated online on a secure online banking transaction. Worse, you had no clue it was happening or anything was even wrong. Scary stuff!

In the "old" days, malware stole usernames and passwords and the criminal would manually steal your cash. Criminals are smart also. Somewhere they created a new deadly trojan horse called, URLzone. It is considered the next generation thief.

The new virus lets them log in with authentication and hijack the account by spoofing (faking)bank pages. The victim and the attacker access the account simultaneously so the victim is fooled that all is fine. The victim thinks they are online. The virus allows criminals to take a percentage from the victim's bank account so not to trip the bank's fraud alert software. The amount set takes the amount out daily.  In August, the virus stole $17K daily from multiple accounts of a German bank. Nobody had a clue anything was wrong. The virus also senses when itself is being detected and immediately creates fake mules (people who take a cut of the money) making investigation useless.

Silentbanker is old, about three years. It was the first to use a phishing site. A victim would go to it thinking it was legit, the site actually would install malware on the victim's computer without any alarms going off. It took screenshots of bank accounts and redirected users from legitmate sites to altered sites.

Zeus is a botnet and targets specific banks. It defeats the bank's authentication by waiting for a victim to log on and access their accounts successfully. It then creates a facade of the bank and requests for a SSN or other personal info. Zeus' infection is hard to detect because each victim receives a slightly different version of it!

Clampi is another botnet that remains dormant for years and captures a victims user name and password for 4500 financial sites. It then sends the data to the criminals who can access the accounts. Like the others, it does not activate until the victim has logged on and accessed their account. Then, it sends a fake screen indicating that the site is temporarily down. The victim, thinking it is real, now leaves the site. The criminals hijack the real screen and steal the money.

The simple way to avoid this is to do your online banking on a linux machine with firefox browser because most trojans only work on Windows.

The top three anti-virus programs are: G Data, Norton, Kaspersky, with G data the #1.
