context safety score
A score of 44/100 indicates multiple risk signals were detected. This entity shows patterns commonly associated with malicious intent.
brand impersonation
The site marketapp.online presents itself as the official CS:GO/CS2 marketplace application download page, replicating the branding, logo, UI, and content of the legitimate market.csgo.com. The domain marketapp.online is not market.csgo.com, but the page displays 'CSGO Market' branding, uses the official market logo SVG, references '@2026 market.csgo.com' in the footer, and includes hreflang alternate links pointing to market.csgo.com — all designed to make users believe they are on the official site. (location: page.html:156, page.html:108-116, page-text.txt:75)
malicious redirect
The HTML head contains hreflang alternate link tags pointing to https://market.csgo.com/en/download (and other language variants) rather than to the current domain marketapp.online. This is a technique used by impersonation sites to pass SEO signals as legitimate while operating from a different domain, and may deceive users or automated agents into treating the page as equivalent to the official domain. (location: page.html:108-116)
social engineering
The page solicits users to download desktop clients, mobile apps, and browser extensions ('MarketApp Desktop Client', 'MarketApp Mobile', 'MarketApp Extension') while impersonating the legitimate market.csgo.com. Downloading these applications from an unofficial domain instead of the real marketplace could result in malware installation. Features advertised include 'auto-confirmation of trades after downloading the maFile' — the maFile is a Steam Guard mobile authenticator file that grants full account control, making this a high-risk social engineering lure. (location: page-text.txt:39, page.html:191)
credential harvesting
The site is a clone of market.csgo.com's download page, encouraging users to download apps and browser extensions from an unofficial domain. Browser extensions in particular have access to all page data including credentials. The Steam 'maFile' download lure ('Set up auto-confirmation of trades after downloading the maFile') targets Steam authenticator files which contain shared_secret and identity_secret keys that grant full Steam account takeover capability. (location: page-text.txt:39, page.html:191)
hidden content
The embedded serverApp-state JSON block (type='application/json') contains SSR transfer state data including internal localhost URLs ('http://localhost:4201/assets/...'), revealing the server-side rendering infrastructure and internal asset server address. This is information leakage rather than a user-facing threat, but indicates the site was built from the official codebase or a direct copy of it. (location: page.html:241, page-text.txt:89)
curl https://api.brin.sh/domain/marketapp.onlineCommon questions teams ask before deciding whether to use this domain in agent workflows.
marketapp.online currently scores 44/100 with a suspicious verdict and low 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.
