Frequently asked questions
What affects the security of caothang.edu.vn?
A valid SSL certificate still does not prove that caothang.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 caothang.edu.vn use HTTPS, and is its SSL certificate valid?
caothang.edu.vn used a valid SSL certificate at assessment time, valid until October 11, 2026. This status may change when the certificate expires or the server configuration changes.
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.
These 3 failed checks or warnings have the greatest impact on the result for caothang.edu.vn.
Unencrypted legacy serviceA confirmed public legacy cleartext service was found: 27.0.14.14:21 (ftp), 27.0.14.14:110 (pop3), 27.0.14.14:143 (imap).High
Why it matters
Older services such as Telnet, FTP, and unencrypted mail or directory protocols can send passwords and data in readable form. Anyone able to observe the network path may capture them.
What to do
Disable the legacy service or replace it with an encrypted alternative such as SSH, SFTP, HTTPS, or the secure version of the mail protocol.

Session cookies protected from scripts (HttpOnly)1 of 1 observed session-like cookie(s) on the inspected root response do not use HttpOnly.High
Why it matters
HttpOnly prevents browser scripts from directly reading a cookie. It does not fix script injection, but it makes theft of session and authentication cookies more difficult.
What to do
Set HttpOnly on session and authentication cookies unless the application has a documented need to read them in browser code.
Cookies sent only over HTTPS (Secure)1 of 1 observed session-like cookie(s) on the inspected root response do not use Secure.High
Why it matters
The Secure attribute prevents a browser from sending a cookie over unencrypted HTTP. This bounded check scores cookies whose names look session- or authentication-related; other cookies are reported as context but do not by themselves prove that sensitive data is exposed.
What to do
Set Secure on every session, authentication, and other sensitive cookie served by the HTTPS application.

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.
Have @caothang.edu.vn email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 894 exposed email records matching the caothang.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 caothang.edu.vn use, and which CVEs (security vulnerabilities) may apply?

Which public IPs, services, and ports does caothang.edu.vn expose?
The assessment observed 1 public IPs and 11 open ports for caothang.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 caothang.edu.vn have been discovered?
The assessment observed 83+ public subdomains of caothang.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.
