How to read this report
Safety Score evaluates observed signals. Evidence Confidence measures how complete, direct, fresh, and consistent those signals are.
No automated scan can guarantee that a website is safe.

Registrar and domain history
Registered on Dec 30, 2025. Registrar: Cloudflare, Inc..
Recorded expiry date: Dec 30, 2026. Registry data can change.
Connection and hosting evidence
The checked homepage returned HTTP 200.
A valid TLS certificate was observed, expiring Nov 16, 2026.
Threat checks and score context
External malware-provider coverage was unavailable. The report does not treat this missing check as a clean result.
Safety Score: 74/100. Evidence Confidence: 75%. These measure different things.

Key findings
Report is current
The displayed evidence comes from the published immutable scan.
Confidence is separate
Unavailable evidence is shown as missing and never counted as clean.
Verify before sensitive actions
Check the exact URL and context before payments, credentials, or downloads.
Fully explainable
Why this score?
Threat providers were unavailable. The neutral uncertainty baseline is not a clean verdict.
Domain registration age and expiry were checked.
Observed DNS records and network address were checked.
Observed certificate validity and TLS protocol were checked.
Observed security header values were checked for basic protective settings. Empty values, disabled HSTS and unrecognized values receive no credit. This is not a complete browser-policy validation.
Observed site metadata and About page were checked. Publisher-supplied details are not independently verified.
Popularity is weak context, not proof of safety. Unranked sites use a neutral baseline.
Observed HTTP status and final connection scheme were checked.
Server-side analysis
Automated security checks
Local antivirus and phishing checks
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.
Page resource inventory
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.
External threat intelligence
Local checks do not query external reputation databases. An unavailable check is never a clean result.

DNS footprint
DNSKEY presence does not verify the DNSSEC signature chain. Missing records can mean no record was returned or the lookup was unavailable.

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.
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

This is a public vulnerability-reporting contact file. Its presence does not prove that the website is safe and does not change the independent Safety Score.

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

Technologies
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: 2026-10-04T02:40:12.278Z.
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.

Did the scan detect malware on cosoado-lab.com?
ClamAV found no signature match in the sampled homepage HTML. External scripts, downloads and private server files were not checked. This is not a whole-site malware clearance.

The public registry record shows Dec 30, 2025. Registration details may be privacy-protected or updated later.
Did cosoado-lab.com have a valid TLS certificate?
The scanner observed a valid TLS certificate using TLSv1.3. A valid certificate alone does not establish that the site is safe.
