5 threat patterns detected

high

phishing

1 deceptive links where visible host does not match destination host

medium

malicious redirect

The page is hosted at black-sun.hydr0.org but all canonical URLs, assets, links, and content point to mp3.cc (a third-party domain). The canonical tag explicitly redirects to https://mp3.cc/t/947059367-black-sun/, indicating the subdomain acts as a redirect/proxy/mirror layer over mp3.cc content without clear authorization or disclosure. The pre-scan context also confirmed 1 redirect was detected. (location: page.html:9 - <link rel="canonical" href="https://mp3.cc/t/947059367-black-sun/">)

medium

brand impersonation

The page presents itself as MP3.cc (title, logo, branding, copyright '© 2017–2026 MP3.cc') while being served from the unrelated domain black-sun.hydr0.org. This constitutes brand impersonation — users and AI agents navigating to this subdomain would believe they are on the legitimate MP3.cc site. (location: page.html:5 - <title>Black Sun | Download mp3 free, listen music online - MP3.cc</title>; page.html:671 - footer copyright)

low

malicious redirect

All audio file download/play URLs route through fine.sunproxy.net, a third-party proxy domain not affiliated with the hosting domain black-sun.hydr0.org or the branded domain mp3.cc. Audio files pass through an intermediary proxy service, creating potential for traffic interception or substitution. (location: page.html:228 - data-url="https://fine.sunproxy.net/file/..." (all playlist items))

low

hidden content

The base64-encoded strings embedded in all audio file URLs (12 suspicious base64 blobs flagged by pre-scan) within data-url attributes of playlist items are opaque encoded payloads routed through fine.sunproxy.net. While individually they may be encoded file paths, the combination of 12 such blobs passed through an external proxy represents obfuscated routing logic that cannot be verified without decoding and resolving each URL. (location: page.html:228,247,266,285,304,323,342,361,380,399,418,437 - data-url attributes on playlist-play anchors)

FAQ: how to interpret this assessment

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

Is black-sun.hydr0.org safe for AI agents to use?

black-sun.hydr0.org currently scores 62/100 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.

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.
