You have landed here, it means you are facing troubles of Wuapp.exe process. It is a legitimate one, or how you get it. Why is it consuming most of your CPU resources? This guide will help you know about this process, legitimacy and removal.

What is Wuapp.exe process?

Wuapp.exe is a legitimate Windows Update process that is an essential part of the windows operating system. But cyber criminals are using this process to mine for cryptocurrency under the expenses of other users.

There are various legitimate processes that are being used by hacker and cryptominers to imitate it and use for mining process. This helps them to easily escape detection for the anti-malware programs. Once your computer is infected with malicious version of wuapp.exe process, it will connect the computer to the pool of Monero coins to run the mining script.
If you are new to the Crypto-mining or cryptojacking then please go through this guide.

Wuapp.exe take up more than 90% of the CPU and GPU resources of the target PC. So the very first sign is the degraded computer performance. If this is true, then you must not ignore it and quickly follow the removal instructions.

How you can get Miner Malware?

Miners are distributed through fake links, spam email attachments, social media sites and spam bots. As the mining process requires huge amount of resources, so one computer is not enough. So the authors of miner program distribute their scripts in massive amounts to connect to the main mining pool.

Here are some most common ways through which the wuapp.exe miner may spread:

  • Freeware programs, crack codes of games: Many hacked websites embeds the malicious files and payloads of the malware along with the bundle programs. It often comes along with crack codes of games, fake driver installers and system optimizer tools.
  • Social media spam links: We encounter thousands of links within the social media networks, messaging apps, video streaming sites so on. This has now become an easy way to spread the spam URLs or links.
  • Phishing email campaigns: Cyber criminals uses the spam bots to spread the malicious payloads of the virus as email attachments. However, these emails appear to be very catchy that users quickly clicks on the infected link or document. That installs the malware on the system.

How it installs on the system and executes?

Once the user clicks on the malicious link, it silently connects to the hackers server to download the malware and install it on the computer. The download file may consists of the various extensions that all have some specific functions to perform. The file types are:

.exe, .dll, .tmp, .bat, .vbs, .wsf, .js.

After being installed, wuapp.exe Monero miner program does various changes to the internal settings of the system to allow its process to start automatically. The changes may accomplish by this miner are:

Create new Registry entries for Run and RunOnce sub-keys, this helps wuapp.exe process to launch each time system starts. It also provides itself the Administrative privilege to execute its tasks.

The registries created are:


Once it finishes the boot process, the infectious codes is injected to the Microsoft Windows update process that is known as wuapp.exe. This makes the process infected and ready for activating Monero mining.

The code injected is:

wuapp.exe –o –u {wallet of the hacker} –p x –v 0 –t 2

The following command initiates the process that is actually now become the crypto-miner, instead of windows update process. Now, the wuapp.exe process automatically connects to the Monero mining pool through 4444 port along with its Wallet ID .

The wallet Id is the unique Id provided to the miners. In this case, the owner of the ID is the cyber-criminal who owns this. Soon after that, the mining process starts that needs huge computing power. Since the mining process requires huge CPU and GPU power, your computer performance will degraded drastically. You may also get huge electricity bill. Along with that, miners put a huge load on the hardware components that can affect the device.

Cryptocurrency mining is not a illegitimate, but as they require huge computing power to calculate the hashes and that’s why cyber criminals does bad practices to make profit by the expenses of other people.
