While thoroughly investigating potentially unreliable websites, researchers came across a problematic Web page known as flamehammer.top. This particular Web page is specifically crafted for the purpose of promoting browser notification spam. During the research period, it achieved this by employing a deceptive tactic involving a fake CAPTCHA test. Furthermore, flamehammer.top has the capability to redirect users to other websites, many of which are likely to be untrustworthy or potentially harmful.

What's significant about flamehammer.top and similar Web pages is that they are not typically accessed directly by users intentionally typing in the URL. Instead, most visitors find themselves on these Web pages through redirects generated by other sites that are part of rogue advertising networks. These networks are known for their involvement in deceptive practices and often force users onto these unwanted pages without their consent or awareness.

Flamehammer.top Lures Users via Misleading Messages

It should be noted that the content experienced on rogue websites can vary depending on visitors' IP addresses or geolocations.

When the researchers visited the website flamehammer.top, it presented them with a deceptive CAPTCHA verification process. The page featured a cartoon-style character wearing a badge standing next to a robot. The character had a speech bubble instructing visitors to 'Press Allow to verify that you are not a robot.' If a visitor falls for this fraudulent test, they inadvertently grant flamehammer.top permission to display browser notifications.

Upon clicking the 'Allow' button, users risk being taken to other unreliable and potentially harmful pages. More specifically, researchers observed redirects to a Web page promoting a tactic resembling variants of the 'Apple iPhone 14 Winner,' 'Loyalty Program' and numerous others.

Rogue websites often exploit their notification permissions to conduct intrusive advertising campaigns. These advertisements primarily promote online tactics, unreliable or hazardous software, and potential malware, creating a significant threat to users' online security and privacy.

Pay Attention to the Signs of a Fake CAPTCHA Check

Recognizing a fake CAPTCHA check can be challenging because the fraudsters are becoming increasingly sophisticated. However, there are some red flags users can look out for to help identify a fake CAPTCHA:

  • Unusual or Poorly Designed Graphics: Fake CAPTCHAs often have low-quality or poorly designed graphics. Look for signs of pixelation, distorted images, or mismatched fonts, which can indicate that it's not a legitimate CAPTCHA.
  •  Lack of Complexity: Legitimate CAPTCHAs are designed to be challenging for automated bots to solve. If the CAPTCHA seems too simple, such as a basic math problem or a single checkbox, it's likely fake.
  •  Inconsistent or Unusual Instructions: Be cautious if the CAPTCHA instructions are unclear, inconsistent, or don't make sense. Legitimate CAPTCHAs provide straightforward and concise instructions.
  •  Excessive Requests for Personal Information: Be wary if the CAPTCHA asks for personal information beyond what is necessary for verification purposes, such as your name, address, or phone number.
  •  No Accessibility Options: Legitimate websites typically offer accessibility options for disabled users, such as audio CAPTCHAs or alternative methods. If these options are missing, it might be a fake CAPTCHA.
  •  Suspicious Source: Consider the source of the CAPTCHA. If you encounter a CAPTCHA on a website that seems untrustworthy, unfamiliar or has a bad reputation, it's a good idea to be cautious.

If you encounter a CAPTCHA that exhibits one or more of these red flags, exercise caution. It's advisable to verify the legitimacy of the website and consider whether your interaction with the CAPTCHA is necessary. When in doubt, avoid clicking or interacting with suspicious CAPTCHAs, and report them, if possible, to the website's administrators.
