Fujacks – a self replicating virus that uses weak passwords to enter machines

Fujacks wormFujacks is a dangerous worm which is capable of installing password-stealing malware

Fujacks is a dangerous computer worm[1] with the backdoor functionality which lets in a password-stealing malware. It enters victims' computers by exploiting weak passwords and copies itself to network shares. It can also spread via infected external devices or shared files. The malicious code infects all .exe files that are located on the computer and drops setup.exe and autorun.inf files to be able to boot with every Windows system startup. Fujacks virus also disables any security software that is installed on the machine. An interesting fact is that infected icons are changed into a panda holding three sticks.

Fujacks malware is also known as Panda virus in the East, as it primarily targets Chinese users. Nevertheless, it does not mean that Fujacks cannot infect people all around the world.

Users who have never had to deal with computer viruses are mostly at risk. Worms are especially dangerous, and Fujacks worm is also capable of stopping anti-malware tools from working. Nevertheless, it is possible to stop the the virus. Users should install FortectIntego or Malwarebytes or other security software and remove Fujacks from their computers. To start an anti-virus program safely, victims should enter Safe Mode with Networking.

Fujacks can enter machines via infected external devices, such as DVD or the USB stick. The cyber infection copies the malicious payload into the root directory of removable drives as setup.exe and also adds autorun.inf to launch the virus automatically.

Virus:Win32/Fujacks.D also scans all the devices connected to the same network and places a copy of itself into System32\GameSetup.exe. To access shares, the worm uses a list of easily-guessable passwords, such as 111, 123abc, login, password, qwerty and similar.

The main executable spoclsv.exe is dropped into \drivers. Fujacks virus then adds the following registry[2] entry to ensure persistence:


Additionally, the virus can delete several registry entries that are related to anti-malware software or other security measures. What is more, Fujacks removes all GHO files that are essentially backup files that can be used to restore data.

Unfortunately, there are minimal infection symptoms. Nevertheless, users can check for the following:

  • added registry value svcshare with data \drivers\spoclsv.exe
  • added file spoclsv.exe in the following location: system32\drivers

Additionally, victims may observe some problems with their security software. It may fail to start, become nonresponsive, crash, etc. Therefore, if your anti-malware applications are struggling, make sure you check for virus infection and perform full Fujacks removal in Safe Mode.

Worms can enter your machine if you are careless

Computer infections don't just enter your machine while it is not being used, as experts[3] explain. Meaning, for malware infiltration, there is always a trigger, and it is a human's interaction with the device. Therefore, make sure you stay safe online by practicing secure internet browsing and computer usage habits.

First of all, make sure you use unique and secure passwords for each of your accounts. As the worm can brute-force passwords, it is always a good idea to secure every account promptly.

Next, you should always take caution when connecting unknown external devices to your computer. Even if it comes from somebody you trust – they don't even know that their USB stick or the DVD is infected. Therefore, make sure you scan the file using security software before opening.

And finally, stay away from suspicious websites, such as porn, file-sharing, online dating and similar. These sites are prone to hacking and can contain malware inside.

Remove Fujacks virus from your machine

Because the virus affects files of security software, Fujacks removal might be a bit complicated. Nevertheless, it is possible. Users should not try to start anti-malware application in normal mode but enter Safe Mode with Networking.

If security software still does not work, victims should download and install a new version. In Safe Mode, capabilities of the virus will be disabled. As soon as the new anti-malware tool is installed, users should perform a full system scan. Using FortectIntego or Malwarebytes, remove Fujacks virus safely.

How to prevent from getting worms

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
