| The Banker-AR Trojan horse attempts to fool
Brazilian surfers into entering their bank login details. |
Experts at Sophos have warned computer users about Trojan horses
that try to fool users of a number of banks into entering their
account details.
The Troj/Banker-AR Trojan
horse and Troj/Banker-K Trojan
horse are designed to steal information from users of a number of
Brazilian online banks.
Once a computer is infected with one of the Trojans internet
activity is monitored, and if it is determined that the computer
user is visiting one of a number of Brazilian banking websites a
fake login page is displayed.
"The fake forms popped up by the Trojan horses are intended to
steal confidential login information such as account numbers and
passwords," said Graham Cluley, senior technology consultant for
Sophos. "Unlike traditional 'phishing' attacks the way these Trojan
horses work means that the user can have their credentials stolen
even if they have visited a legitimate banking site. It's not the
website that tricks them, but the Trojan horse working in the
background."
Although these particular Trojan horses only target users of
Brazilian banks, Sophos warns that computer criminals can easily
adapt the trick for use against any website.
"All computer users should be running an up-to-date anti-virus
as well as protecting their PC with firewall technology. This,
combined with the safe computing practice of exercising caution
over what you choose to run on your computer, can dramatically
reduce the risks of these kind of attacks," continued Cluley.
