Sampled scripts and pages

Resource analysis incomplete

6 resources checked · 12 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.

Page resource inventory

Linked scripts12
Inline scripts0
Embedded frames0

Counts describe the sampled HTML, not every resource loaded by the browser. External resources are common and are not automatically harmful.

No listed local patterns observed. The limited rule set cannot detect every threat or behavior.

Provider coverageNot checked

Local checks do not query external reputation databases. An unavailable check is never a clean result.

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.

SPFNo matching record returned for this exact hostname
DMARCNo matching record returned for this exact hostname

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.

Responsible disclosure

security.txt

RFC 9116 observation

No readable security.txt file was observed at the standard locations. This is informational and is not evidence of malware.

Browser protections

Security headers

0 observed

Header evidence is unavailable. Missing data is not treated as a clean result or proof of compromise.

Response headers

Cookie protections

Passive observation

No Set-Cookie header was observed on the sampled homepage response. Other pages may set cookies separately.

Detected stack

Technologies

Bootstrap 80% Cloudflare 98% Next.js 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

4 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-10-17T02:40:06.539Z.

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.

Recommended maintenance checks
