Today we’d like to introduce an intriguing piece of malware called Nimisi – a Trojan specifically designed to steal your sensitive data once it’s comfortably crept into your system.
What Does Nimisi Do?
What makes Nimisi an intriguing Trojan is that it injects a code into running processes. This feature not only makes it harder to detect and remove, but it serves great to hackers who aim to reach your banking details, login credentials for emails, social media websites, online games, and what not.
According to Microsoft.com, once in your system, it creates the following files:
- %TEMP% \iepv.exe
- %TEMP%\passwordfox.exe
Malware researchers have spotted Nimisi connecting to the www.download.windowsupdate.com and tazbot.mooo.com remote hosts because, according to Microsoft, it needs to:
- Check for an Internet connection
- Download and run additional malware
- Report a new infection to its author
- Receive instructions from a malicious hacker
- Search for your IP address
- Upload the data taken from your PC
- Validate a digital certificate
How to Know If You Have Nimisi
The most certain symptom of Nimisi’s presence in your system is the awdaw2214a
mutex.
In computing, “mutex” derives from “mutual exclusion object” and is a component created to prevent more than one copy of the threat running on your computer. It allows multiple program threads to share the same resource, although not simultaneously.
How Does Nimisi Enter Your PC?
Trojans usually enter your PC via infected websites, files, emails, attachments, etc. Nimisi has been detected to sneak into your system while you download free programs from the Web, too. To keep your system clean and sensitive data safe, therefore, you must always pay attention to what files/websites you open, and what programs you install.
Keep in mind that in most cases the freeware available out there is usually bundled with PUPs (potentially unwanted programs) and various malicious components that could truly destroy your system and even your life.

As you have already read, Nimisi is dangerous because it’s specifically designed to steal your data. On top of that, it can also delete or hide important system files and use your memory space and system resources in order to run. All that could cause system crashes and even the “Blue Screen of Death.”

Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by Nimisi on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
