A Banking Trojan is one of the many types of Trojan Horses. In computer and network safety, a Banking Trojan is any malicious program deployed to obtain confidential information about a bank’s customers and online banking systems.
We have observed numerous Banking Trojans affecting banking facilities all around the world. A new sophisticated threat of the kind has been registered with extreme activity in Japan. The Trojan is dubbed Shifu and combines the best features of previously active banking malware. According to IBM research, Shifu has attacked more than 14 banks in Japan and may be employed in other countries as well.
Shifu’s Set of Malicious Features
According to researchers at SecurityIntelligence, Shifu arrives with several built-in capabilities, supplemented by additional modules once it contacts the command-and-control server:
- Anti-research, anti-VM and anti-sandbox tools.
- Browser hooking parser.
- Screenshot and certificate grabber.
- Endpoint classification, monitoring applications of interest.
- Remote-access tool (RAT) and bot control modules.
The Shifu Banker is capable of stealing multiple banking-related details such as:
- Usernames and passwords connected to financial accounts.
- Credentials keyed into HTTP forms.
- Private certificates.
- External authentication tokens.
Thanks to its sophisticated set of features, cyber criminals behind Shifu can take over bank accounts and make it look like a children’s game.
However, that’s far from everything this Banker Trojan can do. Shifu is also designed to steal data from smart cards. The latter can happen if a smart card reader attached to the affected endpoint is located. Once this is done, Shifu can ‘scan’ and empty cryptocurrency wallets on attacked systems. Furthermore, the Trojan can detect if a point-of-sale system (PoS) is present and can steal credit or debit card data.
If any of the malicious activities described above seem familiar to you, it’s probably because Shifu has ‘rented’ many features of other popular banking Trojans such as Shiz, Dridex, and Zeus. IBM researchers have discovered the Domain Generation Algorithm Shifu uses to generate random domain names for botnet communications – the very same one used by Shiz.
Other features are borrowed from the Zeus Banker such as the ability to disable anti-virus tool. Additionally, Shifu has taken the ability to conceal itself in the Windows file system from Gozi. A functionality typical for the Conficker worm is also included in the Trojan – the capacity to wipe the local System Restore point to cover its tracks.
Shifu has also borrowed means from the Corcow Banker that was viral in 2014 among Russian and Ukranian banks – the methods used to steal credentials, authentication tokens, and sensitive information.
Shifu Infection Methods
It’s not a surprise that malware researchers refer to the Trojan as Frankenstein and ‘uber patchwork’. It is clear that the creators of Shifu know their way around malware and can combine old with new techniques. One of its most curious features is how the Trojan attempts to avert other malicious pieces from attacking the systems it has already infected. Once the Trojan is inside the system, it will launch an antivirus-related component that will scan for other threats and prevent them from downloading onto the machine.
Files received from insecure HTTP connections will be blocked, as well as unsigned or executable files. Files labeled as malicious will be copied to the local disk and will be named ‘infected.exx’, then they will be uploaded to the command and control server. Shifu will then send an ‘out of memory’ message to the system in the attempt to launch the malicious file on the compromised computer.
Shifu is not the first Trojan that will try and stop other malware pieces already located on the system. What is new here is the Trojan’s ability to block actively new malware from being installed onto the infected system.
What Are the Chances of Infections in Other Locations?
Even though the threat was detected only Japan, the chances of it spreading to other countries are quite real. The list of targeted banks can be changed in just a few minutes. Since Shifu is an expert in combining old and new techniques, nobody knows what his creators will decide to do next.

How to Remove Shifu from Windows.
Step 1: Boot Your PC In Safe Mode to isolate and remove Shifu
Step 2: Uninstall Shifu and related software from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it.
Step 3: Clean any registries, created by Shifu on your computer.
The usually targeted registries of Windows machines are the following:
You can access them by opening the Windows registry editor and deleting any values, created by Shifu there. This can happen by following the steps underneath:
Get rid of Shifu from Mac OS X.
Step 1: Uninstall Shifu and remove related files and objects
1. Hit the ⇧+⌘+U keys to open Utilities. Another way is to click on “Go” and then click “Utilities”, like the image below shows:
- Go to Finder.
- In the search bar type the name of the app that you want to remove.
- Above the search bar change the two drop down menus to “System Files” and “Are Included” so that you can see all of the files associated with the application you want to remove. Bear in mind that some of the files may not be related to the app so be very careful which files you delete.
- If all of the files are related, hold the ⌘+A buttons to select them and then drive them to “Trash”.
In case you cannot remove Shifu via Step 1 above:
In case you cannot find the virus files and objects in your Applications or other places we have shown above, you can manually look for them in the Libraries of your Mac. But before doing this, please read the disclaimer below:
You can repeat the same procedure with the following other Library directories:
Tip: ~ is there on purpose, because it leads to more LaunchAgents.
