Nymaim Trojan – Technical Information
Nymaim Trojan is the name of a banking Trojan horse. This Trojan is rather old, but is still found in some way out in the wild, infecting users’ computers. An executable process related to the Trojan horse is involved in spreading it. That process is usually hidden as a legitimate service of your operating system. The [wplinkpreview url=”https://sensorstechforum.com/goznym-banking-trojan-august-2016-attacks-german-banks/”]GozNym Banking Trojan back in August 2016 is a relatively newer variant of Nymaim and is still attacking users worldwide. This type of Trojan horses is known to take up a really small portion of your computer’s resources at first, to infiltrate your computer’s defenses, embed itself into system processes and remain undetected until it does what it is designed to do – stealing banking credential data and accounts.
When Nymaim is launched on a device, it will attempt to either lock the screen or download additional malware. If the user is located in a country in Europe or North America, the malware will download a customized lockscreen for that particular country. The lockscreen will display a ransom demand. If the user is in a country for which no customized lockscreen is available, Nymaim will download a second-stage component which can be used at a later time to download additional malware.
The Nymaim Trojan is not a system file and not related to Windows, but could tamper with Windows processes and files as it follows:
→%UserProfile%\Application Data\[RANDOM FOLDER NAME]\[RANDOM FILE NAME]
The Trojan horse will drop the file listed above, once it is executed on a compromised machine.
Next, the Trojan creates the following registry entry so that it executes whenever Windows starts:
→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce\”[RANDOM STRING]” = “%SystemDrive%\Documents and Settings\All Users\Application Data\[RANDOM FOLDER NAME]\[RANDOM FILE NAME]”
The Nymaim Trojan then creates the following registry entry:
→HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\”Shell” = “%SystemDrive%\Documents and Settings\All Users\Application Data\[RANDOM FOLDER NAME]\[RANDOM FILE NAME],explorer.exe”
Nymaim Trojan malware is highly likely to make some additional components that will aid it to achieve its purpose to full effect. Thus, after it being executed on the system, it may establish a remote connection to a command and control server where all other malicious files are available. There are some essential Windows folders in which the malicious files can be dropped:
