Questions about www.isosklo.cz
- Is www.isosklo.cz safe?
- The scan of www.isosklo.cz on 13 Aug 2026 reached no verdict either way (score 0). Too little was captured to judge it, which is an unknown rather than a pass.
- What malware is associated with www.isosklo.cz?
- 1 analysed samples communicate with this URL, including Phishing.
- How was www.isosklo.cz checked?
- A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the fast 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.
