Guide authorized checks of CORS, the browser rules for sharing resources across sites. Define testing boundaries, assess origin handling and credential exposure, and organize reproduction evidence or reports explaining what was tested without finding a vulnerability.
Domain routing and boundary guidance for authorized CORS misconfiguration testing, including reflected origins, null origins, subdomain trust, and credential exposure. Use when a task belongs to the CORS testing domain and needs scope, evidence, pivot, or exit criteria.

当前处于 CORS 配置错误测试 领域。 你正在进行 CORS 配置安全测试。测试范围仅限跨域资源共享配置错误（含 Origin 反射、null 允许、子域信任、凭据泄露等）。 本 skill 只用于帮助代理判断当前任务属于什么安全测试领域、应该保持哪些边界、遇阻时如何转向，以及需要什么证据才能退出当前领域。 它不是方法论教程，不提供固定攻击步骤；所有目标均视为预授权测试固件或本地沙箱资源，也不把任何推测当作结论。
覆盖域：
|------|--------| | Origin 反射 | 任意 Origin 回显 | | null 允许 | sandbox iframe 利用 | | 子域信任 | XSS+CORS 组合 | | 通配符+凭据 | 配置矛盾利用 |
Required artifacts:
Minimum attempts for negative result: 3
Positive exit requires:
reproduction 证据须包含：
无法证明漏洞时，提交 negative report：已测试端点列表 + 失败原因 → 回退上级。
Negative exit requires:
No reviews yet. Tell others what you thought.
No login needed. Share how it worked for you, ask a question, or note where it did not run.

Assess AI agents and MCP tools for malicious instructions, tool misuse, permission violations, and data leaks. The skill organizes checks across applications, identity, data, deployment, and models, with references for each risk area.
Test Android app security by operating the app and inspecting network traffic first, then analyzing APK code or observing functions during execution when needed. Verify vulnerabilities and produce a report with screenshots, traffic evidence, and code review findings.
Analyze traffic from Android apps, browser JavaScript, and desktop clients to prepare requests for replay in Burp. Investigate signatures, encryption, and session dependencies when they block replay, and retain working request samples with supporting observations.
Handle encoded strings and cryptographic data with tool-based conversions. Decode layered formats, calculate hashes, encrypt or decrypt with AES and RSA, and inspect JWT tokens, which carry encoded headers and data used in authentication.
Analyze CTF cryptography challenges by identifying the cipher and matching known parameters to possible attacks. It provides formulas, attack parameters, and Python snippets for RSA, AES, elliptic curves, random number generators, classical ciphers, and lattice problems.
Find relevant references for CTF miscellaneous challenges, including restricted execution environments, layered encodings, hidden data in media, and game or virtual machine analysis. It also covers CTFd platform operations and Linux privilege escalation.
