AI Security Verdict

Low Risk

Confidence: 82%

Risk Score

CodeSandbox embed of a user's demo sandbox. Self-branded, no forms or credential/payment fields, no Indicators of Compromise or malware signatures. Benign developer content; only the sandbox payload itself could change.

Risk Factors (2)

User-generated content on a shared code-hosting platform, so the specific sandbox payload can change at any time

Elevated eval()/Function() usage consistent with code-editor tooling rather than a specific attack pattern

Safety Factors (5)

Domain matches the self-declared brand (CodeSandbox) — no impersonation of another entity

No forms, no password/payment fields, no credential exfiltration across origins

No threat-intelligence matches, no YARA malware, no malicious kit roster entry

IDS alerts are only informational 'free hosting domain' notices (Misc activity), not phishing or malware signatures

Cross-origin fetches (raw.githubusercontent.com, the sandbox's own csb.app preview host) are normal for a code-preview platform

Domain age information unavailable
