Sampled scripts and pages

Resource analysis incomplete

5 resources checked · 3 script links observed on the homepage. Partial resource coverage.

ClamAV inspects the fetched homepage HTML on our server. New scans also sample up to four linked scripts and two collected internal pages, with size and time limits. Scripts are not executed. Other downloads, private server files and logged-in pages remain outside this check. A signature match needs investigation and can be a false positive. No match is not a whole-site safety guarantee.

Exact hostname lookup uses a downloaded Phishing.Database snapshot. It does not send this domain to an external lookup API or mark sibling subdomains as harmful. Not listed does not mean safe. Snapshot age is download age, not proof that every entry was recently revalidated.

Homepage HTML only · Eight local rule families · local-security-v2

Checks use the fetched page and redirect chain. Scripts are not executed, forms are not submitted, and linked files are not downloaded. This is not a malware clearance.

DNS observations · no external lookup API

Domain email protection

Exact-host SPF and DMARC observations help the owner investigate email impersonation risks. They are separate from website malware checks and do not change the Safety Score.

SPFPolicy record observed, not fully validated
DMARCPolicy record observed, not fully validated

What to do next

Review the records with your mail administrator. Inventory legitimate senders and test SPF and DKIM alignment before enforcing a stricter DMARC policy. Fix duplicate records and investigate overly permissive SPF rules.

This bounded check does not send email, probe SMTP, evaluate recursive SPF includes, verify DKIM signatures or apply organizational-domain DMARC inheritance. A missing subdomain record does not prove that no inherited protection exists. A DNS timeout is unknown, not an absent record. A policy record is not proof that messages authenticate successfully.

Bootstrap 80% Cloudflare 98% Google Tag Manager 96% Tailwind CSS 72%

Versions are shown only when publicly exposed by the page or response headers. An observed version is not, by itself, proof of a vulnerability.

JavaScript library advisories

3 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-09-29T02:40:05.559Z.

No supported library version was identified in the sampled files. This does not establish that the scripts are safe.

A version match is not proof that the website is infected or that an issue is exploitable here. Owners should review the advisory, check whether their code is affected and test an update. Up to four external script files are sampled, not every dependency, inline script or dynamically loaded resource.
