Is the website “www.eb2.hust.edu.vn” safe?
As of September 12, 2026 at 08:01, www.eb2.hust.edu.vn has a security score of 92.7/100 (grade U: “Unrated”), but this result is provisional because some required evidence is incomplete. CyStack’s automated assessment recorded 6 issues to review after completing 49.3% of applicable checks. The website owner should address “DMARC blocking policy” first, then review the remaining items in order of impact.
Does www.eb2.hust.edu.vn show known scam, phishing, or malware signals?
At assessment time, CyStack did not find www.eb2.hust.edu.vn or related infrastructure on any scam, phishing, or malware warning list after checking 5 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.
Potentially exposed domain email addressesChecks infostealer data for email addresses ending in @hust.edu.vn, the registered domain of the assessed website www.eb2.hust.edu.vn. A record is not counted merely because someone visited or signed in to the website.563 matching email exposure records
563Matching email exposure records

These matching email records were observed previously, but they may already have been addressed or may no longer be valid. The device count estimates infected devices associated with these email records; it is not the number of devices owned by the organization.
Frequently asked questions
What affects the security of www.eb2.hust.edu.vn?
A valid SSL certificate still does not prove that www.eb2.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.eb2.hust.edu.vn use HTTPS, and is its SSL certificate valid?
HTTPS on www.eb2.hust.edu.vn could not be reached during this assessment, so its SSL certificate and transport encryption could not be evaluated.
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 www.eb2.hust.edu.vn.
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.
Potentially sensitive subdomainsCyStack confirmed at least 465 active DNS subdomains of hust.edu.vn. 13 names may expose sensitive services; discovery was partial, so more may exist.Medium
Why it matters
Names containing admin, development, staging, VPN, database, or monitoring terms may point attackers toward valuable systems. A name alone does not prove exposure, but it identifies a surface that should be reviewed.
What to do
Potentially exposed domain email addresses found563 email exposure records ending in @hust.edu.vn are associated with approximately 67 infected devices. These are intelligence observations; they do not prove that the email accounts are still active or that the devices belong to the organization.Medium
Why it matters
Infostealer intelligence may contain credentials associated with the domain, but it does not prove that an account is current, valid, or still exposed.

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 @hust.edu.vn email addresses appeared in exposed data or information-stealer (infostealer) logs?
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.
Which public IPs, services, and ports does www.eb2.hust.edu.vn expose?
The assessment observed 1 public IPs and 0 open ports for www.eb2.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.
Remove obsolete DNS names and protect non-public systems with strong authentication, MFA, network allowlists, or a VPN.
Diagnostic information
Subdomain discovery did not complete, so the current list may be incomplete.

Review the masked evidence and observation time, validate affected accounts and devices, then reset active credentials and sessions, enforce MFA, and remove malware where confirmed.
Evidence and check scope
How exposed email records are matched:
Only email addresses whose domain exactly matches this website
Collection refresh status:
completed
Matching exposed email records:
563
The actual record count may be higher:
No
Estimated infostealer-infected devices:
67
Device count is estimated:
Yes
How to interpret this evidence:
Matched records contain an email address whose domain exactly matches the assessed website's registrable domain. Credential records are intelligence observations, not proof that an account is still active. Estimated victim devices are infostealer infection devices associated with matched records; they are not evidence that those devices are owned or operated by the assessed organization.
