Server-side analysis

Automated security checks

Local antivirus and phishing checks

ClamAV · homepage HTMLLocal antivirus is not enabled
Phishing.Database · exact hostnameLocal feed snapshot unavailable

Sampled scripts and pages

Resource antivirus is not enabled

0 resources checked · 2 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 scripts2
Inline scripts5
Embedded frames1
External script hosts0

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

Partial analysis. Only the first 512 KiB of the page were inspected.

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

External threat intelligence

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.

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.

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

Google Tag Manager 96% Nginx 93% WordPress 95%

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

JavaScript advisory analysis could not be completed or no eligible script files were sampled. No clean result is implied.

Recommended maintenance checks

NginxReview the Nginx branch and keep security patches current. Avoid exposing detailed server version headers.
WordPressKeep WordPress core, themes and plugins updated. Remove unused plugins and review administrator accounts.

Did the scan detect malware on slso.org?

External threat-provider coverage was unavailable for this scan, so malware status is unverified.

The public registry record shows Nov 21, 1997. Registration details may be privacy-protected or updated later.

Did slso.org 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.

The website's About page describes its purpose in the report above. This is publisher-supplied information and is separate from independent security findings.

Can a paid listing change this website's score?

No. Premium placement and owner-supplied pages are labelled separately. Technical evidence, the Safety Score and moderation decisions remain independent.
