The researchers discovered the rogue page during their investigation into untrustworthy websites. This particular Web page functions by engaging in browser notification spam and redirecting visitors to various websites, which are likely to be unreliable or hazardous. Users typically encounter pages like through redirects that occur when they visit websites that utilize rogue advertising networks.

Exercise Caution When Dealing with Rogue Sites Like

The behavior of rogue webpages can vary depending on the visitor's IP address or geolocation. These Web pages may host and promote different types of content based on these factors.

During the investigation, it was observed that the page employed a deceptive tactic involving fake CAPTCHA verification to push browser notifications. The Web page displayed a robot image alongside text instructing visitors to click 'Allow' if they were not a robot. If a visitor falls for this deception and clicks the 'Allow' button, they unintentionally granted permission to display notifications, which turn out to be advertisements.

Upon clicking the 'Allow' button, it led to a redirect to a website commonly used for promoting adware, browser hijackers, Potentially Unwanted Programs (PUPs) and other suspicious software.

Rogue websites exploit browser notifications to carry out intrusive advertising campaigns. These advertisements often endorse online tactics, untrustworthy or harmful software and even malware. Consequently, when users encounter pages like, they are at risk of system infections, serious privacy breaches, financial losses and identity theft.

How to Recognize a Fake CAPTCHA Check?

Users can recognize that they are dealing with a fake CAPTCHA check by paying attention to certain indicators. Firstly, they should consider the context in which the CAPTCHA is presented. If they encounter a CAPTCHA verification process on a website or Web page that doesn't require any sensitive information or doesn't involve any high-security activities, it may raise suspicion.

Secondly, users should carefully examine the design and appearance of the CAPTCHA itself. Legitimate CAPTCHAs typically have a recognizable and standardized design, often involving distorted or scrambled characters that need to be identified or entered correctly. If the CAPTCHA design looks unfamiliar, unprofessional, or inconsistent, it may be a sign of a fake CAPTCHA.

Additionally, users should be cautious if the CAPTCHA process is too simple or doesn't seem to serve its intended purpose. Legitimate CAPTCHAs are designed to verify that a user is human and prevent automated bots from accessing certain functionalities. If the CAPTCHA seems too easy to solve or doesn't appear to serve any meaningful purpose, it could be a fake.

Furthermore, users should be wary if the CAPTCHA verification is being used as a tactic to manipulate them into taking a specific action, such as clicking on an 'Allow' button or providing personal information. Legitimate CAPTCHAs are primarily focused on verification and security, rather than manipulating user behavior.

In summary, users should be cautious of any CAPTCHA checks that appear in contexts where they are not typically required, have unfamiliar or inconsistent designs, seem too simple or pointless or are used to manipulate user actions. Staying vigilant and being aware of these signs can help users recognize and avoid fake CAPTCHA checks.
