Neverquest

Neverquest is an online banking trojan that steals login credentials from victims. Researchers have determined that Neverquest is part of the evolving threat family "Snifula," first seen in 2006. This trojan provides attackers with control of the infected device through a Virtual Network Computing (VNC) server, making it appear that the malicious activity is actually coming from the victim’s computer, a method used to avoid detection. It steals credentials by modifying content on banking websites viewed through certain web browsers and injecting fraudulent forms into the banking websites. Neverquest is an evolved, complex piece of malware as it possesses the ability to replicate and distribute itself with the help of FTP servers, the Neutrino Exploit Kit, and social networking websites. It maintains persistence by using "recurring runkey" to rewrite entries into the Windows registry and "watchdog" which reproduces terminated processes. Neverquest also uses a web-injection process to evade detection by antivirus software and bypass security measures such as two-factor authentication. Lastly, Neverquest can perform man-in-the-middle and man-in-the-browser attacks, harvest email, FTP, and stored browser credentials, and has video and screenshot capture capabilities. In 2015, a Neverquest variant known as “Vawtrak” targeted more than 15 Canadian financial institutions, spread through drive-by downloads. Heimdal Security identified 15,000 infected computers.
