Wuapp.exe Miner Malware – Infection
In order to infect computers, the wuapp.exe miner does not target any computer in particular, but rather spreads via massive distribution tools, like spam bots that send web links online on forums or chats or files uploaded for free download online. Such files are often:
- Fake setups of a program you may be looking for.
- Key generators.
- Software license activators.
In addition to simply being uploaded passively online, the wuapp.exe miner may also contain various different types of files or infection scripts on URLs that can be spread via malicous spam e-mails that may be sent to you via spam bots, configured to make the spam e-mails appear very realistic and trustworthy, like the fake dropbox e-mail below, containing link to an external malicious site:
Wuapp.exe Miner Malware – More Information
As soon as the wuapp.exe malware has infected your computer, the virus may connect to a remote host and download it’s malicious payload. The payload may consist of more than one file and the files may be of the following file types:
→ .exe, .dll, .tmp, .bat, .vbs, .wsf, .js
As soon as the malicious files of wuapp.exe Monero miner have been downloaded, the virus may set a registry entry in the Run and RunOnce sub-keys of Windows which may result in the malware running automatically on Windows boot. The sub-keys have the following locations:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
After this has been done, the wuapp.exe monero miner may perform injection of malicious code within the legitimate Microsoft Windows process wuapp.exe, also known as the Windows Update process. The malicious code which is used by the miner malware is the following:
→ wuapp.exe –o pool.minexmr.com:4444 –u {wallet of the hacker} –p x –v 0 –t 2
This command activates the update service as an administrator after the wuapp.exe miner malware has already gained administrative privileges and makes the legitimate Windows Update file to connect to a mining pool via the port 4444 with the wallet ID of the cyber-criminal, who is behind the malware. This results in your computer immediately to begin calculating hashes and hence mine for the Monero cryptocurrency, which requires primarily power from your GPU (Graphics Processor). And since GPU usage is not visible via Task Manager, the process appears to look legitimate and not use a lot of the central processor while mining.
And while the hacker may not mine for a lot of the cryptocurrency from one infected computer, when he adds up hundreds of those, this makes a small mining farm(Figure 1) that generates an insane amount of Monero on his wallet, which is then anonymously sold on the exchanges and black markets. And all of this is done at the user’s expense and if the wuapp.exe miner malware remains on your computer for longer periods of time, it may even damage your video card after overheating it and overusing it.
