Browser notification spam in general

We have investigated numerous rogue pages; lightninganvil[.]top, abyssalforge[.]top, and streamvideoplayer.co[.]in are just a few examples. These websites display browser notifications that primarily endorse deceptive/malicious content.

While legitimate products or services may be encountered via these ads – they are highly unlikely to be promoted by their actual developers. It is most probable that this promotion is performed by scammers who abuse the content's affiliate programs in order to acquire illegitimate commissions.

How did mastason[.]com gain permission to deliver spam notifications?

Websites require user consent to deliver browser notifications. Therefore, if you are receiving these adverts from mastason[.]com – it means that you have likely visited this webpage at some point and enabled their delivery by selecting "Allow", "Allow Notifications", or a similar option.

It is worth mentioning that rogue webpages commonly utilize deception (e.g., adult-oriented content, clickbait fake CAPTCHA tests, etc.) to trick visitors into enabling notifications.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving unwanted browser notifications – do not permit questionable websites to deliver them (i.e., do not click "Allow", "Allow Notifications", etc.). We advise ignoring or denying notification requests from such pages (i.e., selecting "Block", "Block Notifications", etc.).

Should your browser continuously force-open dubious sites without prompt, it could be caused by adware installed on it or the system. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
