Is the website “www.mts.ru” safe?
As of September 22, 2026 at 07:06, www.mts.ru has a security score of 88/100 (grade B: “Good”). CyStack’s automated assessment recorded 7 issues to review after completing 97.3% of applicable checks. The website owner should address “Correct file-type handling (nosniff)” first, then review the remaining items in order of impact.
Does www.mts.ru show known scam, phishing, or malware signals?
At assessment time, CyStack did not find www.mts.ru 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 @mts.ru, the registered domain of the assessed website www.mts.ru. A record is not counted merely because someone visited or signed in to the website.32 matching 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.mts.ru?
A valid SSL certificate still does not prove that www.mts.ru 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.mts.ru use HTTPS, and is its SSL certificate valid?
www.mts.ru used a valid SSL certificate at assessment time, valid until November 5, 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 www.mts.ru.
Correct file-type handling (nosniff)The inspected root response does not set X-Content-Type-Options to nosniff.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.
Scope of this check
This check only evaluates the homepage response and content that the scanner could reach. Other pages and sign-in flows may use different settings.
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.
Automatic redirect to HTTPSThe HTTP root eventually reaches HTTPS but passes through an additional cleartext HTTP address or later downgrades before doing so.Medium
Why it matters
Visitors may enter an address beginning with HTTP or follow an old link. Redirecting them immediately to HTTPS prevents the rest of the visit from continuing over an unencrypted connection.
What to do
Redirect every HTTP URL directly to its corresponding HTTPS URL without passing through another HTTP address.

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 @mts.ru email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 32 exposed email records matching the mts.ru 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.mts.ru expose?
The assessment observed 1 public IPs and 2 open ports for www.mts.ru. 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 mts.ru have been discovered?
The assessment observed 1,363+ public subdomains of mts.ru. 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.
