WellMess Trojan – Virus Infection Methods
WellMess Trojan is being distributed against targets using a variety of techniques. The malware can be used as a weapon by different hacking groups who have access to this tool. It has been known to be used in active attack campaigns since 2018. The Trojan is written in the Go programming language and also compatible with the .NET framework. As a result the WellMess Trojan comes in two variants — 32 and 64 bits architectures are supported.
There are two main distribution techniques:
- Payload Droppers — The Trojan code can be carried by various types of files such as application installers. They are often of popular software that is commonly installed by end users — this can range from productivity and office programs, system utilities and even computer games. The hackers usually make them by embedding in the necessary code in the installation executable files.
- Malware Files Hosting — An alternative is the creation of macro-infected documents — they are of all common formats such as presentations, text documents, databases and spreadsheets. When they are opened by the users a prompt will be shown to them asking them to enable the macros. When this is done this will trigger the Trojan downloading to the host computer and its execution.
During most of the attack campaigns so far the majority of versions were mainly created to be compatible with the modern versions of Microsoft Windows. In one of its more prominent campaigns a hacking group has used the WellMess Trojan against COVID-19 vaccine research organizations. Instead of pushing it through standard distribution tactics the hackers are using advanced techniques such as deep network reconnaissance in order to find the most suitable infection method.
The WellMess Trojan according to its release can differ in their behavior sequence and method of infection. Some of the earlier samples depended on being downloaded by the users from malware sites under the form of legitimate software.
WellMess Trojan – Virus Capabilities
When the Trojan has infected a given computer the main engine will start a data gathering module — it is designed to harvest sensitive user data and system metrics. Some of the data that is obtained by it includes the computer name, domain name, hardcoded values and etc. This will generate a string which is created to identify each hacked host.
Like other malware of this category the WellMess Trojan will install a local client agent which will establish a secure and persistent connection to a hacker-controlled server. This virus can do it over three protocols: HTTP, HTTPS and DNS, thus making the traffic much more difficult to trace. The data which is sent and received is masked in order to remain hidden from analysis.
One of the acquired samples shows how the virus operates on an infected machine — it can load and run PowerShell scripts, as well as ensure that the network connection between the local client and the hacker-controlled server stays persistent. Trojan infections are also commonly used to steal files that are found on the infected computers.
Using the remote connection the hackers can easily reconfigure the operating system. This can lead to numerous malware consequences:
- Boot Options Changes — The hackers can edit the boot configuration files so that the virus will be started automatically. By making these changes the malware can also block the access to the recovery options which will make removal much more difficult.
- Windows Registry Edit — The ransomware can edit the Windows Registry values or create new ones for itself. This will lead to severe performance issues and potential data loss, as well as general system instability.
- Additional Malware Delivery — The Trojan can be used to install other threats to the already compromised systems. Common examples are file encrypting ransomware which will process user data and then request the victims for a ransom decryption fee. Alternatives can be cryptocurrency miners which will take advantage of the available computing power to run complex mathematical tasks. For every completed and reported one back to the controlling servers the hacker operators of the Trojan will be rewarded with cryptocurrency assets that will be directly transferred to their digital wallets.
We recommend that all detected infections are removed as soon as possible in order to protect against further damage to the infected hosts.
