Gamblingday.xyz is a mostly empty website but don't let that fool you - the sole reason for its existence is to propagate a browser-based tactic. There are myriads of websites nearly identical to Gamblingday.xyz and more are created every day. Their only objective is to trick users into subscribing to their push notification by employing various deceitful social-engineering tactics. The crux of the tactic is to convince the unsuspecting users to click the 'Allow' button. By doing so, they will be giving the fraudulent websites the needed permissions to start delivering unsolicited ads directly to the device's screen.
The most popular tactic by far is for misleading websites to pretend that they are performing a bot captcha check. Gamblingday.xyz relies on a different technique, instead opting to take advantage of the user's curiosity. Upon landing on the website, any visitor will be shown a video screen with the following message imposed over it:
Can't play this video! Browser may block video autoplay… Click 'Allow' to play the video
If you agree with the instructions, soon you will be subjected to advertisements for suspicious online game sites or even dubious software updates that may be carrying adware or browser hijacker applications. The sheer volume of unwanted ads could start to interfere with the normal use of the affected device and simply closing the browser will have no effect.
To stop this tactic, users have to open the 'Settings' menu of their browser and navigate to the 'Permissions' section. Once there, look for Gamblingday.xyz and revoke all permissions that have been granted to it.
