Trojan.broluxa is a spyware type of trojan that is mainly utilized when targeted attacks on individuals or organizations take place. The trojan includes exploit scripts that take advantage of several Windows vulnerabilites and it creates files in the Windows file system that are started afterwards. What is more the trojan may be downloading other malicious files via an active connection with a remote location. This threat is also reported by Symantec researchers to use phishing web links in order to steal user entered data.
Trojan.Broluxa – How Did I Get Infected?
This type of trojan is mainly used for targeted cyber-attacks. This means that it may come specifically tailored according to your OS, antivirus shields and firewall program. Targeted infections come via many techniques:
- Spoof email messages – mails sent from an address that resembles a one known to the user or is the same. These attacks are usually done when the cyber-criminal has access to the local network of an organization or when they know an individual’s mail address’ contact list.
- Direct attack on the computer – occurs when the PC is unattended and can be accessed physically by a cyber-crook. The criminal may either open an online link that deliberately infects the PC, disable antivirus and firewall protections to activate the virus and others.
- Malicious link sent out by someone in an online chat.
- Malicious link being distributed as a reply or a comment in a forum or anywhere else online.
Trojan.Broluxa – More About It
Once activated on the computer, the trojan may take advantage of the vulnerabilities CVE-2014-6332 and CVE-2015-5119. Once the trojan has been executed it is reported to create the following files in the user profile:
The file names of the files are usually different by the most often met executable names are:
→svchost.exe; notepad.exe; dllhost.exe, explorer.exe
Modern trojan horses like to choose the same names of their executables as some respectable windows executable files to disguise themselves from antivirus programs.
What is more, this particular trojan horse uses a bank URL list that it downloads from another location:
The downloaded list is then saved in a url.txt file in the %Temp% Windows folder.
Also, the trojan is reported to download yet another list that is being saved eventually as the ‘title.txt’ file, same as the URL list. The location for the list is last reported to be this one:
This is done with the purpose to fulfil the missing elements of what this trojan exactly aims to do. Its main activity involves monitoring internet browser on compromised computers and compares browser URLs and titles with the data in the saved .txt files. Also, the website reported which is luxurybro.co.kr is being blocked from most antivirus software and rendered unsafe.
If the trojan detects matches between the two, it makes a new iexplorer.exe process. It then attacks the user directly by setting these phishing pages in order to steal any user entered information:
The phishing sites may be exactly the same as the websites users visit daily, such as the Facebook login page or anything else. The worse thing is that users may not even know that this is happening. One symptom of identifying a phishing page is if the page refreshes when you press the ‘Login’ button and says something like ‘Wrong password’, even if the user typed it correctly. This is no guarantee that you have a phishing page but it is one way to detect them.
The consequences for the user may be many, main of which may be the loss of his financial information or username, mail address, passwords and other credentials.
