Frequently asked questions
What affects the security of techcombank.com.vn?
A valid SSL certificate still does not prove that techcombank.com.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 techcombank.com.vn use HTTPS, and is its SSL certificate valid?
techcombank.com.vn used a valid SSL certificate at assessment time, valid until March 28, 2027. 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 techcombank.com.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.
HSTS availabilityThe HTTPS response does not contain an effective HSTS policy.Medium
Why it matters
HTTP Strict Transport Security (HSTS) tells a browser to use HTTPS automatically on future visits. This reduces the chance that a visitor is downgraded to an unencrypted connection.
What to do
After confirming that every required page works over HTTPS, send the Strict-Transport-Security header on all HTTPS responses.
Potentially sensitive subdomainsCyStack confirmed at least 122 active DNS subdomains of techcombank.com.vn. 3 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.

Have @techcombank.com.vn email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 126 exposed email records matching the techcombank.com.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 techcombank.com.vn expose?
The assessment observed 1 public IPs and 1 open ports for techcombank.com.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 techcombank.com.vn have been discovered?
The assessment observed 122+ public subdomains of techcombank.com.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.
