How to Spot and Avoid Untrustworthy Websites: A Step-by-Step Guide

By

Introduction

Every day, millions of users encounter websites that seem legitimate but are designed to trick them. These sites aren't always outright phishing pages—they often operate in a gray area, using cleverly worded terms of service to hide hidden subscriptions, fake services, or irreversible payments. Avoiding these traps requires vigilance and a systematic approach. This guide will walk you through the essential steps to identify and steer clear of websites with an undefined trust level.

What You Need

Step-by-Step Guide

Step 1: Examine the Domain Name Closely

Start with the website's URL. Untrustworthy sites often use strange domain names designed to mimic real brands or lure you in. Look for:

If the domain looks fishy, proceed with caution. Legitimate businesses rarely use random or complex domain names.

Step 2: Check the Domain Age

Use a WHOIS lookup tool to find when the domain was registered. According to Kaspersky research, over 90% of suspicious websites are less than 6 months old. If the domain was created in the last few months, treat the site with extreme skepticism. Look for a registration date older than one year; this is a good sign of legitimacy.

Step 3: Review the Website's Content and Promises

Read the site's main pages carefully. Trustworthy sites avoid over-the-top claims. Red flags include:

For example, Kaspersky data from January 2026 shows that fake browser extensions mimicking security software were the most common global threat – they often promise free protection but steal your data.

Step 4: Inspect Payment Methods

Scammers prefer payment methods that are hard to reverse. If the only payment options are cryptocurrency (Bitcoin, Ethereum), bank transfers, or prepaid cards, that's a major red flag. Legitimate businesses typically offer credit cards, PayPal, or other buyer-protected methods. Avoid sites that demand irreversible payments, especially for services that seem too good to be true.

Step 5: Analyze Security and Technical Indicators

Even if a site has an SSL certificate (the padlock icon), that doesn't guarantee trust. But you can check advanced signals:

Kaspersky Premium, Android, and iOS apps now include a "Sites with an undefined trust level" category that uses these signals to flag suspicious resources automatically.

Step 6: Look Up the Company's Reputation

Search online for the business name plus words like "scam," "review," or "complaint." Check social media pages and forums. For regional examples from Kaspersky's data:

If you find no digital footprint or only negative mentions, it's a strong indicator of a trap.

Step 7: Read the Terms of Service and Privacy Policy

Most users skip these, but they're where scam sites hide their loopholes. Look for clauses that:

If the language seems deliberately confusing or overly protective of the site, walk away.

Step 8: Use Automated Filtering Tools

Install comprehensive security software like Kaspersky – its new web filtering category automatically detects resources with undefined trust levels. This provides a safety net. Even if you miss a sign, the software can block the site or warn you before you interact with it.

Tips and Final Warnings

Note: WHOIS lookup services may have changed due to privacy regulations (e.g., GDPR). Use a reliable WHOIS provider that shows registration data if available.
