## Full analysis


### Overview

This Chinese-language website presents a programming and technical-development platform built around coding problems, competitions, community discussion, interview preparation, paid Plus membership, app access, and recruitment or job-referral content. Its apparent business model is primarily educational and community-based, with ancillary commerce and enterprise services.


### Scam/Impersonation Risk

No contradictions were observed. The site content is consistent with an established LeetCode-branded educational and community service: it contains programming problem libraries, algorithm-training materials, competitions, discussion posts, and ordinary registration and login pathways, with no detected phishing, impersonation, or malicious-content indicators. Community recruitment and referral posts introduce the usual need to assess individual listings separately, but they do not, on the available evidence, indicate that the website itself is deceptive. Runtime inspection recorded external network activity and page changes, but the observed behavior was not accompanied by cloaking, hidden forms, externally submitted password forms, wallet-drainer activity, or clipboard hijacking.


Evidence:
- The homepage identifies the service as “力扣 (LeetCode)” and provides programming problems, competitions, community discussion, interview-training content, Plus membership, app access, and recruitment-related sections.
- The domain was registered on 2013-08-11 and is approximately 13.01 years old.
- Historical records show 529 archive snapshots spanning 2013–2026, with 14 years tracked and no suspicious repurposing or semantic-drift finding.
- External reputation checks recorded 0 malicious detections and 0 suspicious detections; the site was ranked 40550 and remained within the top 1,000,000 sites.

### Regulatory Verification Notes

The available evidence supports an established, apparently legitimate educational and content platform rather than a financial or otherwise regulated service. The reviewed content does not present a licensing authority or registration number; this is a disclosure and verification point, not evidence of a scam. The real-world operator identity remains independently unverified, so on-site branding and registration records should not be treated as conclusive proof of the operating legal entity. The registration record identifies 阿里云计算有限公司（万网） as registrar and lists 领扣网络（上海）有限公司 as the owner; those records are useful identity context but do not independently establish the current operator or commercial relationship. No broker-reputation match was identified.


Evidence:
- The homepage describes a content, community, membership, app, store, enterprise-service, and recruitment model, without presenting a regulated financial-service offering.
- The registration record lists registrar 阿里云计算有限公司（万网） and owner 领扣网络（上海）有限公司.
- The site’s TLS certificate uses DV validation, was issued by YR1, and is valid through 2026-10-11.
- The reviewed content contains no stated license authority or license number.

### What to Verify Next

Before credential or payment interactions, independently confirm the operating legal entity through an official corporate or legal source rather than relying solely on site branding. For Plus membership, app, store, or enterprise transactions, review the applicable merchant identity, cancellation and refund terms, and payment-protection arrangements. Recruitment and referral links should be validated through the relevant employer’s independently sourced careers channel before personal information or application materials are submitted.


Evidence:
- The homepage provides separate registration, login, Plus membership, app, store, and recruitment pathways, creating distinct account, payment, and information-sharing surfaces for review.
- Runtime inspection detected no hidden forms, no externally submitted password forms, no wallet-provider activity, and no wallet-drainer runs.
- The site’s transport encryption was valid during inspection, supporting secure channel use but not independently proving operator identity.

### Summary Verdict

The overall posture is **high trust and low risk**, and the available evidence is consistent with an established, apparently legitimate website. No scam, phishing, impersonation, or identity-conflict indicators were observed, although the operator’s real-world identity is not independently verified.


### Infrastructure Integrity

The website is protected by Cloudflare’s CDN/WAF infrastructure. Observed traffic terminated on Cloudflare edge servers in the United States, with all identified addresses associated with AS13335 and no origin-server candidate identified; this reduces direct exposure of the hosting environment but is a mitigating infrastructure control, not proof of legitimacy.


Evidence:
- Served through AS13335, CLOUDFLARENET — Cloudflare, Inc., US.
- Observed edge addresses were 104.18.12.180, 104.18.13.180, 2606:4700::6812:cb4, and 2606:4700::6812:db4.

### Closing Assessment

Normal browsing and ordinary platform use are proportionate to the assessed posture; credentials or payments should proceed after the standard independent merchant-identity, terms, and payment-protection checks appropriate to the intended transaction.

## About this assessment


A trust score summarises the evidence TrustSniffer could collect about leetcode.cn at assessment time. It is a starting point for your own judgement, not a guarantee: a high score means the signals were consistent with a legitimately operated site, a low or critical score means several risk patterns were present.

TrustSniffer assesses a website from the evidence it can collect at a point in time: domain registration and age, hosting and certificate, the content the site served, and third-party reputation feeds. A score is a summary of that evidence, not a guarantee and not a legal finding. There is no human rating and no user review in it. A site can change after it is assessed.
