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.

Independent evidence brief

What we observed about tiasang.com.vn

Updated Oct 2, 2026

The latest scan examined 10 public pages on tiasang.com.vn. Website descriptions below come from the site itself. Registration, connection and threat findings were checked separately.

Purpose and visible content

On its homepage, the site says: Tri thức khai phóng - Khoa học vì con người. Cập nhật góc nhìn mới nhất về khoa học, công nghệ và văn hóa…

Registrar and domain history

A reliable creation date was not returned by the registration lookup. The report leaves domain age unverified rather than guessing.

Connection and hosting evidence

The checked homepage returned HTTP 200 in about 2000 ms.

A valid TLS certificate was observed, expiring Dec 15, 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: 64/100. Evidence Confidence: 70%. These measure different things.

Sampled scripts and pages

Resource analysis incomplete

5 resources checked · 7 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.

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.

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.

SPFNo matching record returned for this exact hostname
DMARCMonitoring-only DMARC policy

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.

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: 2026-10-02T02:40:08.012Z.

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.

Recommended maintenance checks

WordPressKeep WordPress core, themes and plugins updated. Remove unused plugins and review administrator accounts.
