context safety score
A score of 53/100 indicates minor risk signals were detected. The entity may be legitimate but has characteristics that warrant attention.
social engineering
Site prominently features and ranks explicit adult content apps alongside regular mobile games, including apps named '欲漫涩免费版' (erotic comics), '色虎视频' (pornographic video), '嫩草影视' (pornographic video), 'purnhurb官网版' (Pornhub clone), '羞羞视频' (explicit video), '麻豆视频' (known adult content brand), '蜜色视频', '蜜桃视频色版', '骚虎影视', '抖阴视频' (TikTok-named adult app), '涩漫天堂', '工口实验室ERPLABS', '魅魔与触手' and others. These are presented deceptively as ordinary 'app downloads' in ranked charts alongside legitimate games, socially engineering users (especially minors) into downloading adult/pornographic content.

brand impersonation
The site lists 'purnhurb官网版最新版本' which is a deliberate misspelling/clone of the Pornhub brand (pornhub -> purnhurb), and '抖阴视频' which mimics '抖音' (TikTok's Chinese name) with a single character substitution to imply an adult version of TikTok. Additionally '星穹铁道官网版' and '原神天理服官网版' claim to be official versions of major games (Honkai: Star Rail, Genshin Impact) but are listed on an unofficial third-party APK distribution site, misrepresenting official branding. '蓝月传奇正版' claims to be a legitimate copy of a major game franchise. (location: page.html:993-994 (purnhurb), page-text.txt:1809-1814 (抖阴), page.html:1378-1388 (星穹铁道), page.html:1469-1478 (原神天理服))
social engineering
The site uses deceptive topic categories and rankings such as '全新未删减的高清视频免费看' (full uncut HD video free to watch), '男生和女生一起羞羞的视频ApP下载大全' (explicit video app collection), 'ehview不用谢我是活雷锋大全', '触手类的瑟瑟游戏' and '触手游戏女生' to drive traffic to adult content through search-engine-optimized topic titles presented as legitimate game/app categories in a ranked list. (location: page-text.txt:1627-1707)
hidden content
A nav menu item 'li.navbar-list' for '最新更新' is hidden with inline style 'display:none;' while a visible equivalent link also exists. This creates a discrepancy between visible navigation and available page elements. While minor, this pattern is used to serve different content to crawlers vs. users. (location: page.html:56 - <li class="navbar-list" style=display:none;>)
malicious redirect
The pre-scan context reports 2 redirects on the domain go9go.cn before the final page was reached. The page loads a JavaScript file from a protocol-relative URL '//www.go9go.cn/skin/js/pbindex.js?1.1' which could contain redirect or behavioral logic not visible in the static HTML. The full content of this JS file was not captured in the scan artifacts. (location: page.html:16 - script src=//www.go9go.cn/skin/js/pbindex.js)
social engineering
The site distributes modified ('变态版', 'bt服', '汉化版', '免费版', '冷狐版') versions of copyrighted games and apps — including titles like '红警2尤里的复仇舰队变态版', '233乐园无实名认证版' (bypassing real-name verification), '工口实验室ERPLABS', '催眠雌小鬼综合症汉化版', '赤莲忍法帖', '户外露出模拟器', '正太战斗绅士' — framed as legitimate downloads. These modified APKs pose significant malware/spyware risk to users who are deceived into downloading them under the guise of free game access.

curl https://api.brin.sh/domain/go9go.cnCommon questions teams ask before deciding whether to use this domain in agent workflows.
go9go.cn currently scores 53/100 with a caution verdict and medium confidence. The goal is to protect agents from high-risk context before they act on it. Treat this as a decision signal: higher scores suggest lower observed risk, while lower scores mean you should add review or block this domain.
Use the score as a policy threshold: 80–100 is safe, 50–79 is caution, 20–49 is suspicious, and 0–19 is dangerous. Teams often auto-allow safe, require human review for caution/suspicious, and block dangerous.
brin evaluates four dimensions: identity (source trust), behavior (runtime patterns), content (malicious instructions), and graph (relationship risk). Analysis runs in tiers: static signals, deterministic pattern checks, then AI semantic analysis when needed.
Identity checks source trust, behavior checks unusual runtime patterns, content checks for malicious instructions, and graph checks risky relationships to other entities. Looking at sub-scores helps you understand why an entity passed or failed.
brin performs risk assessments on external context before it reaches an AI agent. It scores that context for threats like prompt injection, hijacking, credential harvesting, and supply chain attacks, so teams can decide whether to block, review, or proceed safely.
No. A safe verdict means no significant risk signals were detected in this scan. It is not a formal guarantee; assessments are automated and point-in-time, so combine scores with your own controls and periodic re-checks.
Re-check before high-impact actions such as installs, upgrades, connecting MCP servers, executing remote code, or granting secrets. Use the API in CI or runtime gates so decisions are based on the latest scan.

Assessments are automated and may contain errors. Findings are risk indicators, not confirmed threats. This is a point-in-time assessment; security posture can change.
