4 threat patterns detected

high

tls connection failed

Could not establish TLS connection

high

malicious redirect

The domain lk21official.cc failed TLS connection entirely (connected=false, cert_valid=false), indicating the site may be down, parked, or serving content via an insecure channel. The .cc TLD combined with 'official' in the domain name is a common pattern for impersonation or redirect-chain infrastructure used to funnel users through ad networks or malicious redirects before reaching a payload. (location: metadata.json: tls.connected=false, domain=lk21official.cc)

high

brand impersonation

The domain 'lk21official.cc' uses the word 'official' to falsely imply legitimacy or affiliation with a known brand (LK21, a well-known piracy/streaming site). This is a classic brand impersonation pattern where threat actors register lookalike domains with 'official' appended to deceive users into trusting the site, commonly used to harvest credentials or serve malware. (location: metadata.json: domain=lk21official.cc)

medium

phishing

The combination of a .cc TLD domain with 'official' branding, failed TLS, unknown domain age, redacted WHOIS, and unknown hosting reputation are collectively strong indicators of a phishing infrastructure site. The absence of page content despite a reachable URL structure suggests the page may only serve content conditionally (e.g., based on referrer, geolocation, or user-agent), a tactic used to evade automated scanners while delivering phishing pages to real users. (location: metadata.json, .brin-context.md: domain=lk21official.cc, tls.connected=false, whois.domain_age_days=null)

FAQ: how to interpret this assessment

Common questions teams ask before deciding whether to use this domain in agent workflows.

Is lk21official.cc safe for AI agents to use?

lk21official.cc currently scores 43/100 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.

How should I interpret the score and verdict?

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.

How does brin compute this domain score?

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.

What do identity, behavior, content, and graph mean for this domain?

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.

Why does brin scan packages, repos, skills, MCP servers, pages, and commits?

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.

Can I rely on a safe verdict as a full security guarantee?

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.

When should I re-check before using an entity?

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.
