0–100, higher is better. How it is calculated

The website 650288.com operates as a niche lottery information portal primarily targeting Macau and Hong Kong lottery enthusiasts. It provides a variety of lottery-related content including predictions, historical results, and detailed analyses. The business model appears to be content-driven with monetization likely through affiliate betting links. The site is relatively new, with domain registration dating back to 2022, and uses Cloudflare DNS services. Technically, the site employs basic web technologies such as jQuery and standard CSS/JavaScript, with moderate mobile optimization and basic SEO practices. However, it lacks modern security measures such as HTTPS enforcement and security headers, and does not provide privacy or cookie policies, indicating poor compliance with data protection regulations. No direct contact information or corporate identity details are available, which impacts business credibility. Overall, the site is functional but basic, with a low trustworthiness rating due to the absence of transparency and security best practices.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

650288.com positions itself as a specialized lottery tips and data provider for Macau and Hong Kong markets, serving a targeted audience of lottery players. The site offers a broad range of lottery-related content, including detailed predictions, historical data, and analyses, which may attract users seeking an informational edge in gambling. The presence of affiliate betting links suggests revenue generation through gambling referrals. The lack of corporate information, contact details, and compliance documentation limits its credibility and may hinder user trust. The domain's recent registration aligns with the site's content focus, but the absence of privacy and security policies indicates a gap in regulatory adherence. The site operates in a competitive niche with many similar offerings, and its basic technical and business setup suggests a small-scale operation without significant market differentiation.

Security posture

The website currently exhibits a low security maturity level. It lacks HTTPS enforcement details and no security headers are detected, exposing users to potential risks such as man-in-the-middle attacks. There is no evidence of vulnerability disclosure policies or incident response mechanisms. The absence of privacy and cookie policies further indicates non-compliance with data protection standards like GDPR. No analytics or tracking scripts were found, which limits data exposure but also suggests minimal user behavior monitoring. The site should prioritize implementing HTTPS, security headers, and clear privacy documentation to improve its security posture and regulatory compliance. Additionally, establishing a vulnerability disclosure process and incident response contact would enhance trust and preparedness.

Recommendations

  1. Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  4. Provide clear contact information and business identity details to improve credibility.
  5. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website uses a basic technology stack centered around jQuery 1.10.2 and standard CSS/JavaScript. It relies on Cloudflare for DNS services but no explicit CDN or advanced hosting details are evident. The site shows moderate performance and basic mobile responsiveness but lacks advanced SEO and accessibility features. The HTML structure is functional but not optimized for modern standards. There is no evidence of a CMS or modern web frameworks. The site could benefit from modernization including responsive design improvements, SEO enhancements, and adoption of modern JavaScript frameworks or CMS platforms to improve maintainability and user experience.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
