Trojan-Banker.Win32.Banbra.atfl is a banking Trojan that's designed to steal confidential information related to your bank account; Brazil-based accounts appear to be particularly-favored targets of Trojan-Banker.Win32.Banbra.atfl's attacks. Along with a standard assortment of spyware-based functions, Trojan-Banker.Win32.Banbra.atfl also includes fake file information and a (now-revoked) digital certificate to enhance its appearance of authenticity. While this isn't the first time SpywareRemove.com malware researchers have seen malware using fraudulent certificates, Trojan-Banker.Win32.Banbra.atfl's usage of this tactic may be indicative of banking Trojan embracing this strategy, which can lead victims into trusting files that actually are malicious. As such, anti-malware programs should be used to identify and delete Trojan-Banker.Win32.Banbra.atfl as is appropriate.
Trojan-Banker.Win32.Banbra.atfl: Possibly the Next Phase in the Evolution of Banking Trojans
Trojan-Banker.Win32.Banbra.atfl's most newsworthy trait is its inclusion of a faked digital certificate – a 'virtual signature' that's often used to verify that the file or program in question has been confirmed as reputable by independent organizations. However, the information that Trojan-Banker.Win32.Banbra.atfl used to acquire its certificate includes junk data, such as a free Yahoo address for the e-mail contact, and Trojan-Banker.Win32.Banbra.atfl's credentials are just a method of making Trojan-Banker.Win32.Banbra.atfl seem less harmful than Trojan-Banker.Win32.Banbra.atfl really happens to be.
SpywareRemove.com malware researchers have seen similar tactics with other PC threats, most importantly including Flame, with other examples of fake certificate-using malware including PWS-Duqu and Trojan droppers for BackDoor.DaVinci.1. However, this trick has yet to be widely-embraced by the banking Trojan 'industry,' and Trojan-Banker.Win32.Banbra.atfl's usage may foretell of fake certificates becoming more common than previously for spyware-based PC threats.
While certificates are an easy way of distinguishing fraudulent programs from genuine ones, SpywareRemove.com malware research team also encourages you to use other methods of identifying potential threats to your PC. As long as you scan the EXE prior to executing it, most anti-malware scanners should be able to detect an installer for Trojan-Banker.Win32.Banbra.atfl.
