ACCORDING to Kaspersky, websites with an undefined trust level are web resources that cannot be definitively classified as phishing but are unsafe in their activities, including fake online stores, dubious crypto exchanges, investment platforms and paid subscription services.
The article notes that Kaspersky has introduced a new web filtering category, “Sites with an undefined trust level,” to automatically detect such resources by analysing factors like domain name and age, IP reputation, DNS configuration, HTTP security headers and SSL certificates.
It highlights common indicators, including strange domain names with numbers, cheap top-level domains, recently registered domains, unrealistic promises of earnings, lack of company contact details and payments restricted to cryptocurrency or irreversible transfers. Technical clues include short domain lifespans, hidden WHOIS ownership, missing or misconfigured DNS records, and absence of security headers or valid SSL certificates, as well as frequent redirects or unsafe scripting.
The piece also outlines protective measures and tools, such as trusted online databases and browser checks, and notes that the category is intended to help prevent personal data leaks and financial loss. Dated 06 May 2026, the analysis draws regional context from detection data and emphasises user awareness alongside automated protections.
