Kukinfan[.]com overview
At the time of research, kukinfan[.]com presented us with an imitation of a CAPTCHA verification test. However, it is worth noting that the content encountered on and through rogue sites may differ depending on the visitor's IP address (geolocation).
Completing the fake test grants the webpage permission to deliver browser notifications. These advertisements endorse online scams (e.g., affiliate, phishing, tech support, etc.), untrustworthy/hazardous software (e.g., adware, browser hijackers, PUAs, etc.), and malware (e.g., trojans, ransomware, cryptominers, etc.).
In summary, through websites like kukinfan[.]com – users may experience system infections, serious privacy issues, financial losses, and identity theft.

Browser notification spam in general
Jugingnonsne[.]com, news-jafexe[.]cc, and untiested[.]com are merely a couple of our latest articles on rogue sites. They deliver browser notifications endorsing deceptive and malicious content. Remember that any genuine products/services encountered via these ads are likely promoted by scammers who exploit affiliate programs to obtain illegitimate commissions.
How did kukinfan[.]com gain permission to deliver spam notifications?
Websites cannot deliver browser notifications without user consent. Therefore, you have likely entered kukinfan[.]com and enabled the advertisement delivery by clicking "Allow", "Allow Notifications", or a similar option.
How to prevent deceptive sites from delivering spam notifications?
Should you happen upon a suspicious webpage – do not permit it to deliver browser notifications (i.e., do not click "Allow", "Allow Notifications", etc.). We advise ignoring or denying notification requests (i.e., pressing "Block", "Block Notifications", etc.).
In case of continuous unprompted redirects to questionable sites, check your device for installed adware. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
