These push notifications can also promote fake shopping sites which will take your money and payment info. The latter generally ends up with losing all the money you have on the exposed card.

What are Buycfr pop-up advertisements?

Short summary of the Buycfr.com pop-ups:

Buycfr pop-ups, as opposed, are related to untrustworthy websites. You will commonly witness the proposition to turn them on following the redirection from another site. There’s nothing bad in redirecting unless it throws you to such a questionable place. In this case, turning on push notifications is served as the anti-DDoS check-up. In other cases, the websites can deny showing you the contents unless you apply these push notifications. These requirements should already raise suspicion, as sites commonly feature a more convenient anti-bot mechanism. Witnessing such an requirement should be the reason to skip the site right away. In some cases, even when you click “Allow”, you will not see the site – the sole page it has is a landing page with the offer to turn on the pop-up notifications.

How does it work?

The vast majority of browsers support turning on pop-ups from sites. Websites, on the other hand, can send notifications with the content they like. It may be an advertisement of the product published on this particular website, or a promotion of the page of their partner. As a result, you can see the push notification from site X, but clicking it will direct you to site Y – because a referral link to that website was embedded.

The banners these rascals show are paid under the pay-per-view model. It generally provides a negligible pay for one person, but when you can send ads to a huge number of victims and show them hundreds of ads every day – that is a much more significant sum. Even though the majority of these ads are ineffective, it may still give all the participants a lot of money.

Are Buycfr pop-up notifications dangerous?

Yes, they are. Initially, they may look safe – just a blinking window that appears from time to time. However, the contents of this window differ sharply from what you generally see in pop-up notifications. Buycfr.com website is controlled by crooks, who intentionally throw tons of malicious ads in pop-ups. They also never follow any common sense and can launch sporadic pop-ups into a storm of ads. For weak computers, that may be enough to cause performance issues. But that is not all problems these push notifications carry.
