context safety score
A score of 46/100 indicates multiple risk signals were detected. This entity shows patterns commonly associated with malicious intent.
encoded payload
suspicious base64-like blobs detected in page content
js obfuscation
JavaScript uses Function constructor for runtime code generation
malicious redirect
Third-party ad script loaded from 'dd133.com' using an obfuscated self-invoking pattern that appends a script element dynamically to the document body. The domain 'dd133.com' is not a recognized ad network and the loading technique (immediately-invoked function that creates and appends a script tag with zone ID 10643627) bypasses standard ad-safety checks. This is a common pattern used by malicious ad networks for drive-by redirects or malvertising. (location: page.html:401 - <script>(function(s){s.dataset.zone='10643627',s.src='https://dd133.com/vignette.min.js'})([document.documentElement, document.body].filter(Boolean).pop().appendChild(document.createElement('script')))</script>)
malicious redirect
Third-party script loaded from 'ds.ossetbulimus.com' — an unknown, suspicious domain with no established reputation. The URL pattern '/r3VavJmJBF4n/128600' resembles ad-network monetization infrastructure frequently associated with aggressive redirect chains, pop-unders, and malvertising. Loaded asynchronously with data-cfasync=false to bypass Cloudflare's script safety scanning. (location: page.html:403 - <script data-cfasync="false" async type="text/javascript" src="//ds.ossetbulimus.com/r3VavJmJBF4n/128600"></script>)
hidden content
Ad injection script from 'pubadx.one' pushes ad units using dynamically randomized element IDs (Math.floor(Math.random() * Date.now())) to frustrate content security scanners and make DOM-based ad-blocking harder. The script passes the current page URL (window.location.href) to the ad network via the 'wu' parameter, enabling surveillance of user browsing paths by a third-party ad server. (location: page.html:405-414 - pubadxtag push block with randomized ID and wu=window.location.href)
hidden content
The site claims to offer free reading of commercial manhwa/manga/webtoon content ('Read Manhwa free online') without authorization from original rights holders, as acknowledged in the footer disclaimer: 'All the comics on this website are only previews of the original comics.' This is a copyright piracy site. Such sites are frequently used as lures to expose users to malvertising, as the operators monetize through aggressive ad networks rather than legitimate means, increasing the overall risk of the ad payloads present on the page. (location: page.html:3931 - footer copyright disclaimer)
social engineering
The site meta description uses circled-number Unicode characters ('❶❶✓') and superlative claims ('without annoying ads', 'update fastest, most full') as psychological lures to attract and retain users. These are common social engineering patterns used by piracy sites to build false trust and drive repeated visits, which increases exposure to the malicious ad network scripts also present on the page.

curl https://api.brin.sh/domain/arenascan.comCommon questions teams ask before deciding whether to use this domain in agent workflows.
arenascan.com currently scores 46/100 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.
