Suspicious websites occupy a grey zone between legitimate sites and outright phishing — they manipulate users into voluntarily handing over money or data through fake stores, dubious crypto exchanges, subscription traps, and fraudulent investment platforms. Key red flags include strange domain names, cheap TLDs (.xyz, .top), domains registered less than 6 months ago, unrealistic profit promises, missing contact info, and cryptocurrency-only payments. Technical checks like WHOIS lookups, SSL certificate inspection, HTTP security headers (CSP, HSTS, X-Frame-Options), and DNS record analysis (NS, MX, SPF, DMARC) can reveal fraudulent intent. Kaspersky's January 2026 detection data across 10 global regions shows fake browser extensions mimicking security products are the most widespread threat (found in 9 of 10 regions), while regional patterns vary: Africa is dominated by fake trading platforms, Latin America by betting scams, Russia by binary options brokers and fraudulent subscription services, and CIS countries by crypto scams. Tools like ScamAdviser and APIVoid, combined with Kaspersky's new 'undefined trust level' web filtering category, can help users identify and avoid these threats.
