WannaMine virus Removal Guide
What is WannaMine virus?
WannaMine virus is used for mining Monero cryptocurrency
WannaMine is a fileless malware which is used for mining cryptocurrency. The malicious program was first detected in October 2017 exploiting NSA EternalBlue exploit kit to infect computers.[1] Such functionality makes malware detection, removal, and prevention quite complicated.
WannaMine virus uses the same exploit National Security Agency’s kit that was leaked by Shadow Brokers hackers group in April 2017. However, in May and June, it was used to launch a worldwide WannaCry and NotPetya attacks. Hence, malware targets and infects unpatched Windows OS computers.
Additionally, WannaMine malware uses “living off the land” techniques,[2] meaning that cyber criminals are using and exploiting specific programs or tools that are already installed on the affected computer. In this case, the malware uses Windows Management Instrumentation (WMI) permanent event subscriptions and PowerShell to get persistence and operate on the affected system.
WannaMine works as a computer worm. Thus, once it affects one machine, it continues spreading via the whole network. Therefore, within a short amount of time, all computers on the targeted company or organization might become unusable due to the CPU overuse.
The main purpose of the WannaMine malware is to mine Monero cryptocurrency. The virus tries to take the maximum of computer’s processor’s and RAM’s power to make digital money. According to some reports, malware can use up to 80-100% of computer’s CPU.
Due to the high computer resource’s usage, the affected machine becomes nearly unusable. Hence, immediate WannaMine removal is needed. However, this task may not be simple. Regular antivirus programs might not be capable of detecting the virus. Virus elimination requires using next-generation tools.
In order to remove WannaMine, you can try using FortectIntego or Malwarebytes. However, it’s also important to disconnect a computer from the network as soon as you notice its infiltration. It helps to stop the virus from spreading and affecting devices connected to the same network.

Malware uses EternalBlue exploit kit
The virus takes advantage of EternalBlue exploit kit which uses Windows OS vulnerabilities. Nevertheless, Microsoft patched these security flaws and provided updates. However, many computer users and companies did not install them. Hence, they become victims of malware.
To avoid WannaMine hijack, users are advised to:
- install Windows patches;
- regularly install software updates;
- stay away from illegal, corrupted or suspicious downloads;
- not open unknown email attachments and suspicious links received from contacts;
- install reputable antivirus software that provides real-time protection from sophisticated cyber threats.
Researchers from utanvirus.se[3] also remind that fileless malware is hard to detect and eliminate. Thus, it’s better to take precautions than getting infected with cryptocurrency miner.
Remove WannaMine from the system
WannaMine is a fileless malware. Hence, it’s impossible to remove it manually. As soon as malicious components are executed on the system, malware hides its traces. Thus, basic security programs cannot protect a computer from the attack but are unable to delete the virus too.
To remove WannaMine from the device, you can try using FortectIntego, Malwarebytes or other malware removal software. Next-generation tools should be capable of cleaning your computer from the system.
After WannaMine removal, you should take care of computer’s or network’s security. Upgrade to the latest Windows OS, install available updates, and follow general security tips when browsing the web.

How to prevent from getting malware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
