Visit the source URL for the full interactive report. kstopa.com.cn operates a Chinese domain website. Based on the domain extension, the organization maintains an online presence in China. Specific business activities and services cannot be determined from available information. ## Overview - Domain: kstopa.com.cn - Grade: D (Poor) - Score: 352 / 950 - Last scan: August 31, 2026 - Industry: Manufacturing - Website: https://www.kstopa.com.cn - Location: China ## Vendor risk summary This vendor risk report is based on UpGuard's continuous monitoring of kstopa's security posture using open-source, commercial, and proprietary threat intelligence feeds. The results are summarized into a security rating based on the analysis of hundreds of individual checks across five risk categories: website security, email security, phishing & malware, brand & reputation risk, and network security. ## Security categories ### Website Security - Fail — Secure cookies not used - When secure cookies are not used, there is an increased risk of third parties intercepting information contained in these cookies. The website configuration should be changed so that all 'Set-Cookie' headers include 'secure'. - Fail — CSP is not implemented - No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking attacks. - Fail — X-Content-Type-Options is not nosniff - Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks. - Pass — Server information header not exposed - Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities. - Pass — X-Powered-By header not exposed - Information about specific technology used on the server is obscured. - Pass — X-Frame-Options is not deny or sameorigin - Browsers are prevented from displaying this website's content in frames. This helps mitigate clickjacking attacks. - Pass — HttpOnly cookies used - Using HttpOnly cookies reduces the risk of client side script attacks, by preventing cookies being read on the client. - Pass — Referrer policy is not unsafe-url - The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header. - Pass — ASP.NET version header not exposing specific ASP.net version - Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities. - Pass — ASP.NET version header not exposed - Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities. - Pass — No unmaintained page detected - The page appears to be maintained. ### Email - Fail — DMARC policy not found - DMARC policy was not found. This makes it easier for attackers to send email from this domain. A DMARC policy should be deployed for this domain. - Fail — SPF policy uses ~all - Sender Policy Framework (SPF) record is too lenient as to which domains are allowed to send email on the domain's behalf. This record should preferably not use the ~all mechanism, as this does not instruct the mail receiver to reject messages from unauthorised sources. When DMARC is not being enforced, -all should be used on the SPF record. - Pass — SPF enabled - Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses. - Pass — SPF syntax correct - Sender Policy Framework (SPF) record passes basic syntax checks. - Pass — SPF ptr mechanism not used - Sender Policy Framework (SPF) record does not include the ptr mechanism. ### Network - Pass — No ports are open - No open ports were detected. ### DNS - Fail — DNSSEC not enabled - DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain. - Fail — CAA not enabled - The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain. - Pass — No unregistered MX records detected - No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected. - Pass — No subdomain takeover vulnerability detected - No dangling DNS records that could lead to subdomain takeover were detected. ### Encryption - Fail — HTTP does not redirect to HTTPS - The domain is still accessible over HTTP. All HTTP requests should be redirected to HTTPS. - Fail — Hostname does not match SSL certificate - The site's hostname does not match the SSL certificate. The domain name should be added to the certificate, either as a Subject Alternative Name or as the Common Name. - Fail — SSL expired - SSL certificate has expired. The certificate will need to be renewed for connections to your domain to be trusted. - Fail — HTTP Strict Transport Security (HSTS) not enforced - Without HSTS enforced, people browsing this site are more susceptible to man-in-the-middle attacks. The server should be configured to support HSTS. - Fail — Weak SSL algorithm - Industry standard SHA-256 encryption is not in use. The SSL certificate should be migrated to a SHA-256 certificate. - Fail — Weak public certificate key length - Public key algorithms and key sizes offering less than 112 bits of security strength are no longer considered secure. Public RSA keys should be at least 2048-bit and ECDSA keys should be at least 224-bit. - Fail — Weak cipher suites supported in TLS 1.2 - Weak cipher suites can potentially be broken by a well resourced attacker, and should not be supported by the server unless very old devices or browsers must be supported. - Pass — Certificate not found on our revoked certificate list - The site's certificate chain was checked against our list of revoked certificates. - Pass — SSL available - SSL is supported for this site. - Pass — No insecure SSL/TLS versions available - No insecure SSL/TLS versions are available for this site. ### Data leakage - Pass — No open cloud storage service detected - No cloud storage service configured to allow anonymous file listing was detected. - Pass — Domain index is not a listable directory - The domain index is not a listable directory. ### IP/Domain Reputation - Pass — No reports of botnet activity in the last 30 days - This IP/domain has not been reported as a source of botnet activity in the last 30 days. - Pass — No reports of brute force login attempts in the last 30 days - This IP/domain did not appear on any list of IPs and domains known to perform brute force login attempts in the last 30 days. - Pass — No reports of malware distribution in the last 30 days - This IP/domain has been reported for distributing malware in the last 30 days. - Pass — No reports of unsolicited scanning in the last 30 days - This IP/domain has not been reported for performing unsolicited scanning in the last 30 days. - Pass — No reports of phishing activity in the last 30 days - This IP/domain has not been reported as a phishing site in the last 30 days. - Pass — No reports of botnet activity in the last 90 days - This IP/domain has not been reported as a source of botnet activity in the last 90 days. - Pass — No reports of brute force login attempts in the last 90 days - This IP/domain did not appear on any list of IPs and domains known to perform brute force login attempts in the last 90 days. - Pass — No reports of malware distribution in the last 90 days - This IP/domain has been reported for distributing malware in the last 90 days. - Pass — No reports of unsolicited scanning in the last 90 days - This IP/domain has not been reported for performing unsolicited scanning in the last 90 days. - Pass — No reports of phishing activity in the last 90 days - This IP/domain has not been reported as a phishing site in the last 90 days. ### Vulnerability Management - Pass — Not vulnerable to CVE-2014-0160 (Heartbleed) - A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords. - Pass — Not vulnerable to CVE-2014-3566 (POODLE) - The server does not support SSLv3, and is not vulnerable to the POODLE attack. - Pass — Not vulnerable to CVE-2015-0204 (FREAK) - The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack. - Pass — Not vulnerable to CVE-2015-4000 (Logjam) - The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack. --- Full interactive report: https://www.upguard.com/security-report/kstopa-com-cn Security Reports Policy: https://www.upguard.com/security-report-policy
