What is Captchadecode.com?
Captchadecode.com pop-ups are a social engineering attack that tricks users into allowing push notifications from web sites run by scammers. Scammers use push notifications to bypass protection against popups in the browser and therefore display a ton of unwanted adverts. These advertisements are used to promote questionable browser addons, prize & lottery scams, fake software, and adult web pages.
Captchadecode.com is a deceptive site that displays a fake message claims that clicking ‘Allow’ button will let you access the content of the web-site, enable Flash Player, connect to the Internet, download a file, watch a video, and so on. If you click on ALLOW, this web-site gets your permission to send push notifications in form of popup adverts in the right bottom corner of your desktop.
