Police in Brazil have arrested more than 50 people for stealing an estimated $30 million from Internet bank accounts with a series of phishing Trojan horses such as Troj/Banker-AR and Troj/Banker-K.
The arrests of more than 50 suspected hackers took place across four states in the north of Brazil, with most of those apprehended said to be under the age of 25.
Graham Cluley, Senior Technology Consultant for Sophos said,
"Hackers and virus writers in Brazil seized upon the opportunity to make significant amounts of money by writing these Trojan horses. The Trojans would lurk in the background, waiting for innocent users to enter their bank login details and then secretly pass them back to the hackers. The Brazilian authorities should be congratulated for taking swift action against this activity - fifty arrests give some idea of the huge scale of this kind of organised Internet crime."
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 web sites a fake login page is displayed and the confidential data emailed back to the hacker's email address.
As ever, we recommend you keep your anti-virus software up to date.
