Njw0rm Trojan — How Did I Get It
The Njw0rm Trojan is a well-known malware which has been spotted in several attack campaign over the years. It can be seen used by different hacking groups, both experienced and beginners due to the fact that at a time it was being offered on the dark underground marketplaces for a fee. Developers of malware threat have been offering “builder” options of the Trojan which allows prospective buyers to choose what options and capabilities to include in their own custom variant. Over the years as the development of the main code base expands a lot of version and derivatives have come up.
Depending on the exact capabilities which are requested by the prospective buyers the chosen distribution techniques can vary. One of the most widely used mechanisms is the vulnerability exploit — the criminals will search for weaknesses in the computer networks and if such are found the virus will be installed.
The hackers may use various phishing strategies which are focused on manipulating the recipients into thinking that they have received a legitimate notification from a well-known company or service. There are two forms under which these tactics are commonly organized:
- Phishing Email Messages — They use stolen or faked content and layout in order to appear as legitimate notifications. If the users interact with the shown contents they will either download a virus payload or get infected via a script.
- Application Installers — The hackers can construct malicious installers of popular software that is often deployed by the end users. This is done by modifying the legitimate setup files from their official sources and integrating the necessary code into them. In the end they will be spread to the intended victims via various techniques.
These files can then be spread over file-sharing networks like BitTorrent where both legitimate and pirate data can be spread. An alternative is to upload hacker-made browser plugins to their relevant repositories. They will create descriptions that promise new functionality or performance enhancement. As soon as they are installed the virus will be deployed to the victims.
Njw0rm Trojan — Capabilities
As soon as the Njw0rm Trojan is deployed on a given computer the local client will establish a persistent connection to a hacker-controlled server. As soon as this is done the hackers will be able to carry out all of the possible malware tactics. This will depend on the actual version of the threat which is acquired. Some of the versions can have missing features or extra ones added in.
One of the common mechanisms which is done by almost all strains of the Njw0rm Trojan is to enable a security bypass module — a small-sized script instance will be used to install the Trojan in a way which will bypass or completely remove security software and services installed on the host computer. This includes the likes of anti-virus programs, firewalls, virtual machine hosts, sandbox environments and etc.
Besides the usual Trojan functionality other common modules will be run by the main engine. This includes the usual persistent installation — a way for the malware to be run every time the computer is powered on. In some cases advanced versions of it can be configured to block access to the recovery boot options as well.
The full list of the Trojan commands is the following:
- Run File — Executes a target file on the local machine
- Autoit Script — Copies and pastes a script that is to be executed
- CMD.EXE — Runs a given command on the command line interface
- Update — This will update the local version with the one specified with an URL argument
- Uninstall — This will remove the malware from the infected host
- Builder — This will launch the Trojan’s builder
- About — This command will provide information about the malware’s version.
- Get Passwords — This will list all hijacked passwords and scraped information from the victim machines.
