Frequently asked questions
What affects the security of www.alidns.com?
A valid SSL certificate still does not prove that www.alidns.com is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
Does www.alidns.com use HTTPS, and is its SSL certificate valid?
www.alidns.com used a valid SSL certificate at assessment time, valid until January 7, 2027. This status may change when the certificate expires or the server configuration changes.
Have @alidns.com email addresses appeared in exposed data or information-stealer (infostealer) logs?
Data sources
Data compiled from CyStack cybersecurity monitoring systems
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
TLS 1.0 and TLS 1.1 use outdated security designs and are no longer accepted by modern standards. Leaving them enabled allows older, weaker connection methods.
What to do
Disable TLS 1.0 and TLS 1.1, support TLS 1.2 securely, and enable TLS 1.3 where possible.
Email spoofing protection (DMARC)No DMARC record was found for the registrable email domain.High
Why it matters
DMARC lets the domain owner tell receiving services what to do when the visible From address is not verified by SPF or DKIM. Without DMARC, attackers have more opportunity to impersonate the domain in phishing email.
What to do
Publish a DMARC record at _dmarc, begin by collecting reports, and confirm that legitimate senders pass before applying a blocking policy.
Evidence and check scope
Allowed browser content (CSP)The CSP on the inspected root HTML response contains a broad, unsafe, or missing script-source control recognized by this bounded check.High
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.

This is a quick, point-in-time check from outside the organization. It can surface visible risks, but it does not replace penetration testing or an authenticated assessment.
No record associated with an @alidns.com email address was found in the currently available data. This does not rule out incidents that have not been observed.
Which public IPs, services, and ports does www.alidns.com expose?
The assessment observed 1 public IPs and 2 open ports for www.alidns.com. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
How many subdomains of alidns.com have been discovered?
The assessment observed 376+ public subdomains of alidns.com. This list can reveal additional entry points such as APIs, administration systems, or test environments, but it does not mean that every subdomain is risky.
