01 · Investigation Brief

Investigation Brief

Documented infrastructure purpose

Alibaba Cloud documentation lists ntp.aliyun.com among its NTP servers and explains that these servers enable cloud instances to synchronize time with minimal network latency.

No technical threat detected

The available checks found no threat warning and reported zero malicious and zero suspicious detections across 90 engines.

The registrable domain has also existed for 6,920 days, providing additional context consistent with an established service, though age alone does not prove safety.

Why the score is 98

The score combines saved deterministic evidence with the grounded analysis available for this report. Coverage remains separate so missing sources cannot be mistaken for clean results.

Still, stay alert

No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.

Double-check the exact URL in your address bar
Confirm you are actually on ntp.aliyun.com and not a lookalike like n-tp.aliyun.com or an IDN homoglyph.
Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.

07 · Safety FAQ

Safety FAQ

Common questions, answered directly from the scan data above — so the answers reflect the saved verdict and evidence in this report.

Is ntp.aliyun.com legit and safe?

Our automated security review found no threat indicators on ntp.aliyun.com, so it appears legitimate. All 90 antivirus engines we queried report it clean, and the domain is 19 years old, registered on September 28, 2007 — established domains are far less likely to be scams. Even so, always double-check the exact address in your browser, because phishing emails routinely spoof real, trusted domains like this one.

Is ntp.aliyun.com safe to use?

ntp.aliyun.com has a Safety Score of 98/100 (Safe). Core checks and semantic analysis found no material threat at scan time. Treat unexpected login or payment requests with normal caution.

Could a legitimate site like ntp.aliyun.com still be used in a scam?

Yes — and this is worth understanding. Even trustworthy domains get spoofed in phishing emails (a fake message that only looks like it's from ntp.aliyun.com), and legitimate sites are occasionally compromised on specific pages. A clean verdict means the site itself checks out today; it does not mean every email or link claiming to be from ntp.aliyun.com is genuine. Always reach the site by typing the address yourself rather than clicking links in unexpected messages.

Has ntp.aliyun.com been flagged by antivirus engines?

No — all 90 antivirus and blocklist engines in our malware network currently report ntp.aliyun.com as clean. That's a good sign, though antivirus coverage is only one of the many signals we weigh, and brand-new scam sites can appear clean before vendors catch up.

Is ntp.aliyun.com on any phishing or malware blacklists?

No — ntp.aliyun.com is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.

How old is the ntp.aliyun.com domain?

ntp.aliyun.com is 19 years old, registered on September 28, 2007 through Alibaba Cloud Computing (Beijing) Co., Ltd.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.

Does ntp.aliyun.com have a valid SSL certificate?

No — ntp.aliyun.com has an invalid or broken SSL certificate, so browsers will show a security warning. Combined with the other signals, we recommend avoiding it.

Where is ntp.aliyun.com hosted?

ntp.aliyun.com resolves to an IP operated by Aliyun Computing Co., LTD in CN (Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.

How often is the ntp.aliyun.com report updated?

This report is a record of the scan run on September 9, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about ntp.aliyun.com has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
