Questions about x1.c.lencr.org
- Is x1.c.lencr.org safe?
- The scan of x1.c.lencr.org on 24 Aug 2026 reached no verdict either way (score -12). Too little was captured to judge it, which is an unknown rather than a pass.
- What malware is associated with x1.c.lencr.org?
- 747 analysed samples communicate with this URL, including Zusy, Cryptinject, HUILoader, Avlj.
- How was x1.c.lencr.org 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.
