Nymaim Trojan – Distribution Methods

The Nymaim Trojan malware can spread in a few ways. Third-party installer setups could have put a Trojan horse on your computer system via bundling. These installations typically arrive with freeware and application packages. Without you knowing, additive content could be installed to your computer, which could even be a JavaScript file that downloads the actual malware. Avoiding such installations is possible if you find Custom or Advanced settings in the install setup.

Nymaim Trojan can also spread if you come across unknown websites through redirects and advertisements which have some sort of scripts in themselves and load them when you visit a site or click on an advert. Pop-ups, pop-unders, as well as banners could have links inside of them that can redirect you. When visiting such websites, especially with an unknown origin, they could inject the malware inside your computer device. That can happen via any browser.

Nymaim Trojan has also been found to be delivered via exploit kits, or in files (typically using filenames related to popular keyword searches) which are downloaded from different malicious websites.

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

A new active GozNym campaign has been detected by IBM researchers, this time targeting users of German banks. The Trojan has been updated.
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:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

Here is one of the ransom page lockscreens that show up related to the Nymaim Trojan:

Besides everything said above, the Nymaim Trojan will also attempt to connect to one of the following locations in order to update itself or download other malware:

Below you can see some useful tips that can help you to prevent similar miner malware to install onto your PC, in the future:

  • Run programs inside a sandbox environment
  • Install an advanced anti-malware protection

  • Install an ad-blocker application
  • Be wary around your e-mails and don’t open them unless you know the source
  • Disable macros in Microsoft Office Applications
