What kind of page is captchawall[.]top?

Discovered by our research team during a routine inspection of suspicious websites, captchawall[.]top is a page that promotes browser notification spam. Additionally, this webpage can redirect visitors to other deceptive and malicious sites.

Most visitors to captchawall[.]top and similar websites access them inadvertently via redirects caused by pages that use rogue advertising networks.

Captchawall[.]top overview

We have to preface this by stating that the behavior of sites like captchawall[.]top (i.e., what they load/promote) may depend on the visitor's IP address/ geolocation. Therefore, what users visiting such pages encounter - may vary.

When we accessed captchawall[.]top, it presented us with fake CAPTCHA verification designed to trick visitors into allowing the site's browser notifications. To elaborate, it displayed an image depicting a robot with a speech bubble stating - "CLICK ALLOW TO CONFIRM THAT YOU ARE NOT A ROBOT!".

If deceived into doing so, visitors will enable captchawall[.]top to deliver notifications, which it uses to run intrusive advertisement campaigns. The displayed notifications/ads promote various scams, untrustworthy/harmful websites and apps, and even malware.

Having clicked allow, this webpage redirected us to a site running a scam promising users the prize of an iPhone 13 for completing Amazon's survey. It must be stressed that neither is this scam associated with Amazon.com, Inc., nor are any of its claims true. This scheme is thematically similar to the "Amazon loyalty program" and "Win The New iPhone 12" scams, which we have previously researched.

Browser notification spam in general

The Internet is rife with rogue websites; meovideo[.]ru, worldcoolfeed[.]com, kexvideo[.]ru, and gomusic[.]info are just a few examples of those we have analyzed.

While most of the browser notifications from such webpages endorse dubious/malicious content, it is possible to encounter legitimate products. However, it is highly unlikely to be a promotion approved by their actual developers. Usually, this advertising technique is used by scammers busing affiliate programs to acquire illegitimate commissions.

How did captchawall[.]top gain permission to deliver spam notifications?

Websites cannot deliver browser notifications without user consent. Hence, you've likely permitted captchawall[.]top to display them. Like many rogue pages, this site uses deception (i.e., fake CAPTCHA verification) to lure visitors into enabling its notifications.

How to prevent deceptive sites from delivering spam notifications?

To avoid receiving undesirable browser notifications - we strongly advise against clicking "Allow", "Allow Notifications", or similar options given by suspicious websites, thus permitting them to deliver the notifications/advertisements.

If you access a questionable site, we recommend ignoring or declining notification requests (i.e., "Block", "Block Notifications", etc.). Furthermore, it is crucial to avoid reaccessing such webpages.

Should your browser continuously force-open dubious/dangerous webpages, it is likely due to adware installed onto 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.
