Is the website “cmctelecom.vn” safe?
This report summarizes the security observations recorded for cmctelecom.vn at scan time. Review each check and its evidence for the full context.
Does cmctelecom.vn show known scam, phishing, or malware signals?
At assessment time, CyStack did not find cmctelecom.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 only for email addresses whose domain exactly matches this target. A record is not counted merely because someone visited or signed in to this website.212 Matching email exposure records
212Matching email exposure records
30Related infected devices (estimated)
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.
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.
These 3 failed checks or warnings have the greatest impact on the result for cmctelecom.vn.
Allowed browser content (CSP)The result recorded “Allowed browser content (CSP)” as failed at scan time. Confirm the current condition before acting.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.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.
Evidence and check scope
Correct file-type handling (nosniff)The result recorded “Correct file-type handling (nosniff)” as failed at scan time. Confirm the current condition before acting.Medium
Why it matters
Without the nosniff setting, a browser may guess a file's type and treat harmless-looking content as executable code. This can turn an incorrect Content-Type into a security issue.
What to do
Send X-Content-Type-Options: nosniff on every response and return an accurate Content-Type.
