What is Rank Captcha?

“Rank Captcha” is a scam that poses as a tool to verify if website visitors are human. The scammers use a fake human verification process to trick people into allowing push notifications. They might create a fake verification page or pop-up window that looks like a real human verification, like CAPTCHA or reCAPTCHA. They might ask people to answer questions, click a button, follow a link, or do something else to prove that they’re human. But the real purpose of the fake human verification is to fool people into allowing push notifications.

Once push notifications are enabled by the user, scammers can utilize them to present ads, phishing scams, or other harmful material directly on the user’s device, even if they’re not using the browser.

How the Rank Captcha scam works

Scammers create a fake website that resembles a legitimate one, or they may use pop-up ads, phishing emails, Adware, or PUPs to redirect the user to the fake website. Once on the fake website, the user is prompted to complete a human verification process in order to access content or a feature.

The verification take the form of a question “CLICK «ALLOW» TO CONFIRM THAT YOU ARE NOT A ROBOT!”, or other similar process. As part of the human verification process, the user is asked to allow push notifications from the website. This is the ultimate goal of the scammer, as it will allow them to display malicious content directly on the user’s device.

Once the user has allowed push notifications, the scammers can use them to display ads, phishing attempts, or other malicious content directly on the user’s device. The scammers may also collect personal information from the user, such as passwords, credit card numbers, or other sensitive information, which can be used for illegal purposes.

Push notifications can take on various forms, depending on the intentions of the scammers. Some common forms of push notifications include:

• Pop-up ads: Scammers may use push notifications to display pop-up ads directly on the user’s device. These ads can be disruptive and lead to unwanted data charges or decreased battery life.
• Phishing attempts: Scammers may use push notifications to attempt to trick the user into clicking on a link or entering sensitive information, such as passwords or credit card numbers.
• Malicious content: Scammers may use push notifications to display content that is harmful or offensive, such as adult content or violent images.
• False updates: Scammers may use push notifications to trick the user into downloading malicious software or visiting a fake website by claiming that the user needs to update their software or perform some other action.

Here are some examples of the push notifications:

Rank Captcha can change its content based on the user’s IP address. This is done using IP geolocation technology, which can determine the geographic location of the user based on their IP address. Scammers can use this information to customize the content of their captcha scam page, making it appear more relevant or trustworthy to the user.

For example, if a user is located in a particular country, the scammers may present a fake human verification page in the local language or currency, or they may use images or logos that are familiar to users in that region. The goal of customizing the content based on the user’s IP address is to increase the chances of the user falling for the scam and allowing push notifications.

If the user does not allow push notifications when visiting Rank Captcha, the scammers are able to redirect the user to other malicious URLs. The goal of the scammer is to trick the user into providing personal information, downloading malware, or visiting fake websites that are designed to steal sensitive information or spread malware.
