What kind of page is osx-defender[.]pro?

We inspected osx-defender[.]pro and found that it is crafted to trick visitors into agreeing to receive its notifications. The site uses clickbait to obtain permission to deliver notifications. Usually, if allowed, sites like osx-defender[.]pro send fake warnings and other messages to lure users into interacting with them.

Osx-defender[.]pro in detail

Osx-defender[.]pro displays an image of a robot and a fake CAPTCHA (a checkbox with an "I'm not a robot" message). Also, the site claims that it has registered suspicious traffic coming from the visitor's network and will be able to determine that the visitor is not a robot.

If interacted with, osx-defender[.]pro presents another misleading message instructing visitors to click "Allow" to prove that they are not robots. However, performing this step grants the site permission to show notifications (it has nothing to do with passing a CAPTCHA).

Once permission is granted, osx-defender[.]pro displays fake warnings and possibly other deceptive notifications. These notifications are disguised as warnings from Windows, and they claim that a computer is infected by viruses. They also urge users to turn on protection and delete viruses.

Clicking on such notifications (links provided in them) can expose users to untrustworthy websites. These sites can be crafted to steal sensitive information, such as login credentials, credit card details, or identification data, which scammers can use for identity theft, account breaches, fraudulent transactions, and other malicious purposes.

These websites can also promote fake services or products to trick users into making payments, or they may attempt to install unwanted or dangerous software. It is highly advisable to block notification requests from such sites and revoke any permissions that may have already been granted.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
