Investigate signs of intrusion through hypothesis-led log searches, then turn findings into detection rules. Supports Sigma, YARA, and SIEM queries, with attention to false positives, data field mapping, and validation against historical logs.
Use for blue-team threat hunting, detection engineering with Sigma/YARA, SIEM query design, and incident detection validation.

NOW: 确认蓝队/狩猎授权与数据源范围（SIEM、EDR 导出）NOW: 明确假说（hypothesis）再查数，避免无脑刷告警NEXT: 工具与数据接入方式ACT: 假说 → 查询 → 验证 → 规则化malware-analysis/：样本侧 IOC → 本 skill 落地检测digital-forensics/：案件伪影 → 横向狩猎例：攻击者用 living-off-the-land 做横向
→ 数据源：Sysmon 1/3/10、Windows Security 4624/4648
→ 成功标准：发现异常父进程或罕见账户日志源
□ 基线：正常管理员行为时段与主机

Assess authorized APIs through a ten-stage workflow covering endpoint discovery, authentication, access permissions, input handling, and request limits. Collect reproducible evidence and turn findings into regression checks that can run in a development pipeline.
Inspect Android APKs from the command line to understand app logic, permissions, and components. Supports Java decompilation, low-level code edits, rebuilding and signing, plus Frida observation of running methods and routing to native code analysis.
Plan and coordinate authorized penetration tests across multiple stages, from reconnaissance to access, privilege escalation, movement between systems, and impact assessment. Assign specialist skills, revise blocked paths, and maintain evidence and progress records for the final report.
Transfer known function and variable names from an older binary to a newer version. Compare disassembly and pseudocode with an LLM, produce structured mappings, and apply names and comments in IDA.
Inspect compiled programs in Binary Ninja using strings, function references, and intermediate representations—views of program logic at different levels. Trace data flow and report findings with addresses, supporting evidence, confidence, and reproduction steps.
Automate website navigation, form filling, content collection, and Windows desktop interactions. The skill selects browser or desktop tools for the task and guides screenshot capture and desktop network traffic observation when needed.
