context safety score
A score of 48/100 indicates multiple risk signals were detected. This entity shows patterns commonly associated with malicious intent.
tls connection failed
Could not establish TLS connection
phishing
Domain '9ffyu1g9c.com' is a randomized-looking, non-meaningful string domain (9 random alphanumeric characters) — a common pattern used in phishing and malware infrastructure to avoid brand association and blocklist detection. Combined with a relatively young domain age of 169 days and unknown hosting reputation, this strongly fits the profile of a throwaway phishing or malicious redirect domain. (location: metadata.json: domain=9ffyu1g9c.com)
malicious redirect
The site failed TLS connection entirely (connected=false, cert_valid=false) despite being accessed over HTTPS. A live site at an HTTPS URL that cannot establish a valid TLS session is highly anomalous — this is consistent with a temporary or rotating malicious infrastructure node, a redirect intermediary, or a domain parked for future malicious use. No legitimate site operates this way. (location: metadata.json: tls.connected=false, tls.cert_valid=false)
hidden content
The page returned completely empty HTML, visible text, and hidden content. A registered, recently-active domain (169 days old) serving a fully blank page over HTTPS with a broken TLS certificate is consistent with cloaking behavior — serving empty content to scanners/bots while delivering malicious content to targeted human visitors based on user-agent, referrer, or geolocation filtering. (location: page.html, page-text.txt, page-hidden.txt: all empty)
curl https://api.brin.sh/domain/9ffyu1g9c.comCommon questions teams ask before deciding whether to use this domain in agent workflows.
9ffyu1g9c.com currently scores 48/100 with a suspicious 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.
