Is csst.at legit or a scam?
Phishing and malware site flagged by four antivirus engines; low traffic rank and no business registration.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

MT Intelligence
Four antivirus engines — Chong Lua Dao, CRDF, Gridinsoft, and SOCRadar — flag this domain as malicious or phishing. Gridinsoft and SOCRadar specifically classify it as a phishing threat, which is a strong indicator of credential-harvesting or impersonation activity. The domain ranks outside the top 200,000 globally, suggesting minimal legitimate traffic. The hosting IP (104.26.12.166) has a clean abuse score and no reports, but this does not override the antivirus consensus. WHOIS data is unavailable, preventing verification of legitimate business registration. The SSL certificate is valid but recent (82 days to expiry), which is typical for both legitimate and fraudulent sites.
