Is www.lemma-studio.pl safe?

The scan of www.lemma-studio.pl on 21 Aug 2026 reached no verdict either way (score -6). Too little was captured to judge it, which is an unknown rather than a pass.

How was www.lemma-studio.pl checked?

A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the standard tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
