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
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
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.
Remove Nimisi Immediately
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.”
To remove Nimisi, you must use a legit anti-malware program. Our experts note that the virus is tricky to get rid of, therefore trying to remove it manually or via a random anti-virus tool is highly discouraged if you don’t want to worsen the situation.
