The use of malicious code to access the personal data of Internet users is a practice increasingly used these days. The purpose of these malicious users is almost always motivated by financial interests.
Last year, of the total number of Trojans circulating on the network, 20 percent were used for theft of bank details, making this category of malicious code the most detected by Panda Software laboratories.
Among the most used variants, the «Banker family» stands out, which makes up 52 percent of the detected Trojans, followed by Banbra (39.08 percent), Goldun (6.32 percent), Banks (2.36 percent) ) and with less than one percent, the Banking variant.
The Trojan Banker.CJA, belonging to the family that was most detected in 2006, prevents users from accessing the legitimate banking website, redirecting customers to fake pages where it is possible to steal personal data, says the computer security company.
The next process consists of sending the users’ data to the creator of the malicious code, who subsequently uses it, posing as the account holder.
Panda says that currently no bank can provide «services online, whose users cannot be affected by Trojans outstanding bank accounts «, since» the unique nature of the malware, usually created to achieve a service online very specific, makes it difficult to detect, as new variants are generally not included in the signature files «of traditional protection solutions.
