BlackMoon Banking Trojan – Spread

In order to be widespread successfully, the BlackMoon is believed to use websites of malicious character. Researchers report that the cyber-criminal gang behind the BlackMoon may have uploaded an executable on a malicious web link. This is a sophisticated procedure because such executables may be spread via different means:

  • Posted as spammed comments on websites via Referral Spam bots.
  • Featured in the body of spam-emails as web links which pretend to be legitimate vendors, like PayPal, eBay, etc.
  • Sent in chat messages from fake Facebook profiles or other social media or cyber-communication platforms.

BlackMoon Banking Trojan – In-Depth Analysis

It was reported that the old version of BlackMoon used to attack the Hosts file of a given web browser since it is the main file responsible for URLs, advertisements and other web content. Upon modification, this file was immediately hijacked and modified. This resulted in browser redirects to phishing pages which prompted users to enter their financial information.

Now the infection method is believed to be conducted via a malicious PAC(Proxy Auto-Configuration) file via which it hijacks the user credentials with the assistance of carefully written JavaScript code. To run undetected, the PAC is heavily obfuscated.

The malware also has a pre-set list of Korean websites whose hashes are embedded in it. Via a special script, as soon as one of those websites is detected in the infected computer, the malware displays a pop-up, reported to be an error message:


After this pop-up, BlackMoon immediately causes a browser redirect which leads to a credentials phishing page:


The web pages feature all types of personal and financial information, like name, address, credit card numbers, security numbers and other crucial information which may be profitable for cyber criminals.

What is even worse is that BlackMoon is compatible with almost all web browsers, massively used for Windows, like Google Chrome, Mozilla Firefox, Microsoft Edge. Besides this, researchers have also reported that BlackMoon uses debugging techniques in order to prevent malware researchers or at least delay them greatly from looking into this virus.

BlackMoon Banking Trojan has also been reported to create a malicious process CACLS.EXE, which can fool users that it is a legitimate process, however this process has been reported by Fortinet researchers to not be such that will remain active in the task manager for extended periods of time.

In addition to this, BlackMoon Banking Trojan was also reported to modify or create values in the following registry keys , according to Fortinet Researchers:

→ HKCU\Software\Microsoft\Internet Explorer\Main – StartPage
HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings – AutoConfigURL
HKCU\Software\Microsoft\Windows Script\Settings – JITDebug

Attacks by the BlackMoon threat are believed to be originating from hundreds of different MAC addresses, however the command and control servers of the malware’s botnet are reported to be the following:


Besides being focused on stealing the financial information of users, BlackMoon may also use its Trojan functions to collect other critical data as well. Here is what it may also steal:

  • Mobile number.
  • Passwords.
  • Social Security Numbers.
  • Keystrokes.
  • Whether the computer is part of an organization or a home machine.

How to Detect If You Are Infected by BlackMoon Banking Trojan

In case you feel like your financial information has been compromised, we strongly advise you to follow these instructions in order to check whether or not your computer has been infected with BlackMoon:

Step 1: Download and Install Wireshark

Wireshark is a network sniffing program which sniffs all of the incoming and outgoing packets on your computer. It will help capture malicious information which could be associated with BlackMoon. You can download it by entering their official website via the link below and choosing your operating system and version (Windows 32-bit, Windows 64-bit, macOS).

Enter Wireshark Official Download Page

Step 2: Start Wireshark and configure it to start sniffing packets.

To do this, just start Wireshark after you install it. Then click on your internet connection type from which you will sniff information. You should be able to detect it by the higher amount of traffic generated in its histogram graphic, like in the picture below:


Step 3: Find the packet you are looking for.

Here is where the tricky part comes in. As soon as the packets start to appear you will most likely see the e-mail addresses which are associated with them. You can try to compare from the IP addresses of the command and control servers provided by Fortinet in above (starting with As soon as you see a packet of information coming from one of the addresses, your computer may be infected by this malware.


However, bear in mind that the cyber-criminals behind this malware are most likely migration experts, meaning that they will often use different ip addresses and this is why you should perform a research in google or find a database of associated IP addresses by paste-ing one address in Cqcounter.com/whois. The more IP addresses associated with BlackMoon attacks you collect the higher the possibility you find a match by using Wireshark.

What to Do If I Am Infected?

In case you are an unfortunate victim by this virus, the first and utmost thing you should do Is to (i)shut down your computer from the power and evaluate how much information is compromised. After this, we strongly advise you to (ii)change all of the credentials and transfer your funds to another bank account, preferably in a foreign bank. For maximum security we advise you to use more than one bank account. After doing this, you can proceed with (iii)changing all of your account passwords from a safe computer and removing this malware from yours.

To remove BlackMoon banking Trojan, we strongly recommend that you follow our step-by-step instructions below. They are carefully designed so that you can detect and delete everything associated with this Banking Trojan from your computer. Since manual removal may take you some time, we strongly advise you to use an advanced anti-malware program which will swiftly detect this and other associated malware and permanently delete them from your computer as well as protect it in the future.
