Critical Error IP Threat Detected scam

"Critical Error IP Threat Detected" scam overview

Webpages running the "Critical Error IP Threat Detected" scam imitate the official Microsoft site. Upon access, the visitor is presented with a bogus system scan and multiple pop-ups warning of fake threats. Throughout the scam, the visitor is encouraged to contact "Microsoft Support".

Technical support scams promote bogus helplines; however, how they progress once a victim calls the scammers – can vary greatly. The scheme can be entirely contained within the phone call(s), during which the caller is tricked into disclosing vulnerable information, making monetary transactions, visiting malicious sites, or downloading/installing malware (e.g., trojans, ransomware, cryptominers, etc.).

In many cases, tech support scammers request remote access to victims' computers. This is typically achieved through the use of legitimate software such as UltraViewer, TeamViewer, AnyDesk, or others.

Cyber criminals can cause significant damage whilst connected, and they tend to continue pretending to be "support", "expert technicians", etc., throughout the process. While the victim is kept distracted with technobabble, the scammers can disable or remove security tools, install fake anti-viruses, extract sensitive data, and even infect the device with actual malware.

The criminals can obtain information by tricking the user into disclosing it over the phone, presenting them with phishing websites/files (e.g., disguised as sign-in pages, registration forms, etc.), or by utilizing data-stealing malware. Targeted information can include: log-in credentials (e.g., emails, social networking/media, e-commerce, online banking, cryptocurrency wallets, etc.), personally identifiable details, and finance-related data (e.g., banking account details, credit card numbers, etc.).

Furthermore, the "services" of scammers tend to be exorbitantly priced. Criminals prefer difficult-to-trace methods for obtaining funds, as that diminishes chances of successful persecution and money retrieval. For example, cryptocurrencies, pre-paid vouchers, gift cards, or cash hidden in packages and shipped. What is more, successfully scammed victims are often targeted repeatedly.

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

Should it be impossible to close a deceptive webpage – end the browser's process using Windows Task Manager. Keep in mind that restoring the previous browsing session will reopen the scam site.

If you have allowed scammers to access your device remotely – first, you must disconnect it from the Internet. Second, uninstall the remote access program that the cyber criminals used, as they may not need your consent to reconnect. Last, run a full system scan with an anti-virus and remove all detected threats.

If you have provided your log-in credentials to scammers – change the passwords of all possibly exposed accounts and inform their official support. And if you believe that your other private information has been compromised (e.g., ID card details, passport scans/photos, credit card numbers, etc.) – immediately contact the appropriate authorities.

The Internet is full of deceptive and malicious content. Various scam models are used to gain and subsequently abuse victims' trust. Therefore, we strongly recommend exercising caution while browsing.

How did I open a scam website?

Scam sites are most commonly accessed via redirects caused by webpages using rogue advertising networks, mistyped URLs, spam browser notifications, intrusive advertisements, and installed adware. Deceptive pages may also be promoted through spam campaigns (e.g., emails, PMs/DMs, SMSes, forum posts, etc.).

How to avoid visiting scam websites?

It is essential to be careful while browsing. We advise against using websites that offer pirated software/media or other questionable services (e.g., Torrenting, illegal streaming/downloading, etc.), as these pages are typically monetized via rogue advertising networks.

We recommend paying attention to URLs or entering them with care. Caution must be extended to incoming emails and other messages.

To avoid receiving unwanted browser notifications – do not permit suspect sites to display them (i.e., do not click "Allow", "Allow Notifications", etc.). Instead, ignore or deny notification requests from such webpages (i.e., click "Block", "Block Notifications", etc.).

To prevent harmful/bundled content from infiltrating the system – download only from official/trustworthy sources and treat installations with care (e.g., read terms, use "Custom/Advanced" settings, opt out of additions, etc.).

It is paramount for device/user safety to have a dependable anti-virus installed and kept updated. Security programs must be used to perform regular system scans and to remove threats and issues. If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.
