Avoid getting scammed by fake "Threat Detected: xxbc Detected" websites

What kind of scam is "Threat Detected: xxbc Detected"?

While browsing suspicious sites, our researchers found a webpage promoting the "Threat Detected: xxbc Detected" technical support scam. Schemes of this kind claim that visitors' devices are infected or otherwise in danger and urge them to call bogus support lines. Once the scammers are contacted, they trap victims in an elaborate scheme.

"Threat Detected: xxbc Detected" scam overview

The "Threat Detected: xxbc Detected" scam is disguised as Microsoft's official website. The page is overlaid with multiple pop-ups warning users of various severe threats. Throughout, visitors are urged to call "Microsoft Windows Support".

It must be stressed that all the information provided by "Threat Detected: xxbc Detected" is false, and this scam is in no way associated with the Microsoft Corporation.

The scheme may take place entirely over the phone, but more often, these scams involve remote access. Scammers pretend to be "support", "Microsoft-certified technicians", etc., and request victims to allow them to connect to their devices remotely. The access is typically facilitated using legitimate software, such as UltraViewer, TeamViewer, or similar.

Threats posed by tech support scammers

After cyber criminals establish remote access to victims' computers, they can disable/remove genuine security tools, install fake anti-viruses, obtain vulnerable information, and even cause malware infections (e.g., trojans, ransomware, etc.) – all while pretending to provide technical support services.

Targeted data can include personally identifiable details (e.g., ID card or passport photos/scans, etc.), account log-in credentials (e.g., emails, social media, social networking, e-commerce, online banking, cryptowallets, etc.), and finance-related information (e.g., bank account details, credit card numbers, etc.).

Victims can be deceived into disclosing this data over the phone or entering it into phishing websites/files. Cyber criminals can also acquire it by using information-stealing malware.

What is more, the "services" of tech support scammers carry exorbitant fees. Criminals use difficult-to-trace methods to obtain money, thus minimizing the chances of prosecution and preventing victims from retrieving their funds. For example, cryptocurrencies, gift cards, pre-paid vouchers, or cash hidden in packages and shipped. Note that it is common for successfully scammed victims to be targeted repeatedly.

To summarize, by trusting a scam like "Threat Detected: xxbc Detected" – users can experience system infections, severe privacy issues, financial losses, and even identity theft.

Should it be impossible to exit a scam page – end the browser's process using Task Manager. Do not restore the previous browsing session when opening the browser again since that will reopen the deceptive webpage.

If you have permitted scammers to access your device remotely – disconnect it from the Internet. Afterward, uninstall the remote access software that the cyber criminals used, as they might not need your permission to reconnect. Lastly, run a full system scan with an anti-virus and eliminate all detected threats.

If you have provided your log-in credentials – immediately change the passwords of all potentially disclosed accounts and inform their official support. However, if you have disclosed personally identifiable or finance-related data – contact the appropriate authorities without delay.

Technical support scam examples

We have investigated thousands of online schemes; "Windows Defender Firewall Alert", "Microsoft Windows Firewall Warning", "A Malicious Item Has Been Detected!", and "U.S. Securities And Exchange Commission" are just some examples of tech support scams.

There are countless schemes promoted on the Web. Commonly used false claims relate to system infections, outdated software or subscriptions, package shipping mishaps, lotteries, giveaways, and so on. However, regardless of what this content claims or promises, the end goal is the same – to generate revenue at victims' expense.

How did I open a scam website?

Scam webpages can be force-opened when a site that uses rogue advertising networks is accessed. Alternatively, the latter may generate redirects to the former when hosted content is interacted with (e.g., clicking buttons, pop-ups, text input fields, links, etc.).

Additionally, online scams are promoted by spam browser notifications and intrusive advertisements. Misspelling a website's domain can also result in a redirect (or a redirection chain) landing on a deceptive page.

Spam (e.g., emails, DMs/PMs, SMSes, social media/ forum posts, etc.) is utilized in scam promotion as well. Adware is likewise employed for this purpose. This software can display scam-endorsing ads or force-open sites hosting deceptive content.

How to avoid visiting scam websites?

The Internet is rife with deceptive and malicious content that appears legitimate and innocuous. For example, intrusive ads and spam browser notifications may look harmless – yet redirect users to questionable sites (e.g., scam-promoting, gambling, pornography, etc.).

Therefore, we strongly recommend caution when browsing. Pay attention to URLs and enter them carefully. Be selective about which pages you allow to display browser notifications; ignore or deny these requests from suspect webpages (i.e., click "Block", "Block Notifications", etc.).

We advise against using websites that offer pirated software/media or other dubious services (e.g., illegal streaming or downloading, Torrenting, etc.), as these webpages are typically monetized through rogue advertising networks.

Another recommendation is to be vigilant with incoming emails and other messages. Attachments or links found in suspicious/irrelevant mail must not be opened, as they can be hazardous/malicious.

To prevent bundled/harmful content from infiltrating the device – download from official/verified sources and treat installations with care (e.g., read terms, study options, use "Custom/Advanced" settings, and opt out of additional apps, extensions, tools, etc.).

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:
