Frequently asked questions
What affects the security of www.esso.hust.edu.vn?
A valid SSL certificate still does not prove that www.esso.hust.edu.vn 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.esso.hust.edu.vn use HTTPS, and is its SSL certificate valid?
www.esso.hust.edu.vn used a valid SSL certificate at assessment time, valid until November 13, 2026. This status may change when the certificate expires or the server configuration changes.
Have @hust.edu.vn 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TLS 1.0 and TLS 1.1 use outdated security designs and are no longer accepted by modern standards.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.
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.
DMARC blocking policyThe effective DMARC policy is none and applies to 100% of messages.High
Why it matters
A policy of quarantine or reject tells receiving services to move suspicious mail to spam or refuse it. A monitoring-only policy (p=none) records the problem but does not ask receivers to stop spoofed mail.
What to do
After every legitimate sender passes DMARC, move gradually to quarantine and then reject, covering 100% of messages.

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.
There are currently 563 exposed email records matching the hust.edu.vn domain. These records may be old or already resolved. The website owner should verify them before resetting passwords or locking related accounts.
What technologies does www.esso.hust.edu.vn use, and which CVEs (security vulnerabilities) may apply?
The assessment identified 35 technologies on www.esso.hust.edu.vn, including 3 with a version, but CVE matching did not complete for every version. An empty result should not be treated as proof that no vulnerability exists.
Which public IPs, services, and ports does www.esso.hust.edu.vn expose?
The assessment observed 2 public IPs and 2 open ports for www.esso.hust.edu.vn. 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 hust.edu.vn have been discovered?
The assessment observed 465+ public subdomains of hust.edu.vn. 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.
