Trojan.Luminrat – How Did I Get It?
There are a number of ways you could get infected with the “Luminrat” Trojan horse. The most common distribution method is to install it manually as another program which is under the pretense that is useful. Thus, without knowing, you are getting the Trojan inserted into your system.
You might have been infected with the Trojan from a targeted attack by downloading an attachment from an electronic letter. Files that can be used to spread various threats such as the Luminrat Trojan, more often than not, have these extensions: .bat, .exe, .vbs, .pif, .scr and other executable ones. The Trojan usually hides in your system, by using names with different decimal numbers for its files. You could also get infected via some plugin, extension, popup banner, or a site with malware on it.
Trojan.Luminrat – More About It
Once executed, the Luminat Trojan creates folders in the System Drive, which have decimal numbers as names and the directory path looks something like this:
→C:\92349238498.34445\2014949.24565767\1
Then it inserts a clean file in its main directory, named “helper.exe”. After which, the following registry entries are created in the “HKEY_CURRENT_USER\Software\” key:
→•”Xmy8Wrx1nWVOj522YFIamQ==” = “[BASE64 DATA]”
→•”UeE/t8o052EAyeZxeEkWIg==” = “[BASE64 DATA]”
A backdoor is then opened on the affected computer, which opens a connection through TCP port 7189 and leads to the remote location “lumilogs.ddns.net”.
The Trojan can do a lot of actions on a compromised computer and change settings allowing access to microphones and cameras. It can record audio and webcam footage. It can perform TCP, UDP and Slowloris distributed denial-of-service (DDoS) attacks and open a proxy as well. All the personal data collected from the targeted machine can be sent to a remote location, including the above-mentioned audio and video recordings. On top of that, it may steal email and FileZilla account credentials.
It may also do the following tasks:
•Initiate a remote desktop
•Modify the hosts file
•Self-Update
•Start a remote desktop connection
•Disable Windows Task Manager
•Open a command shell prompt
•Download malicious files
•Traverse files and folders
•Show a message box
This proves that the Luminrat Trojan has dangerous capabilities, including a two-way backdoor to a remote location selected by a cyber-criminal, who can steal very sensitive and personal information from the computer being targeted.
