Nessground.space is a fraudulent website that used various social engineering tactics to trick users into subscribing to its push-notification services by clicking the 'Allow' button. If it is successful, the website will receive all of the browser permissions it needs to start delivering unsolicited advertisements to the screen of the affected device, generating monetary gains for its creators in the process. Due to the specific permissions it gains, Nessground.space can generate advertisements even if users shut down their browser completely.
When unsuspecting users land on Nessground.space, they will be greeted with several fake alert or error messages. The site itself will pretend that a non-specified download is now ready, the only thing left is for users to click 'Allow.' The exact text displayed by the scam website is:
Download is Ready
click Allow to download your file
The advertisements delivered by Nessground.space could expose users to additional risks. They could be redirected to dubious online casino sites or ones offering Potentially Unwanted Programs (PUPs) pretending to be useful applications.
It is better not to open any of the generated advertisements and take the necessary steps to stop Nessground.space from continuing to interfere with the normal use of the affected device.
