No issues found. Passed automated security review. · v0.1.0 How review works →

  • Prompt-injection patterns
  • Secret / credential exfiltration
  • Dangerous shell & filesystem operations
  • Untrusted network calls
  • Known-malicious package signatures

What it can access

  • Network access No
  • Filesystem access No
  • Shell / process execution No
  • Environment & secrets No
  • Dynamic code execution No

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

蓝队检测与响应 · 镇魔盾

> 检测是工程,不是运气。每条规则必须能回答四问:what / why / FP rate / response。 > 站在防御侧,把告警当代码维护、把事件当事故管理、把狩猎当假设验证。 > 信级:项目日志/EDR 原始事件 > Sigma/YARA 规则库 > ATT&CK 官方矩阵 > 训练记忆(标 [unverified])。

路由

| 意图 | 秘典 | 触发词 | |------|------|--------| | SIEM/EDR 规则与调优 | [siem-and-edr](references/siem-and-edr.md) | Sigma, YARA, Splunk, Elastic, Sentinel, EDR, LOLBins, detection-as-code | | 事件响应与取证 | [incident-response](references/incident-response.md) | IR, NIST 800-61, triage, chain of custody, Volatility, memory, runbook, postmortem | | 威胁狩猎与紫队 | [threat-hunting](references/threat-hunting.md) | hunt, hypothesis, IOC, IOA, TTP, ATT&CK, Atomic Red Team, Caldera, 蜜罐 |

执行链

检测:日志源 → 规则编写 → 告警分级 → 调优降噪 → 覆盖矩阵
响应:识别 → 遏制 → 根因 → 清除 → 恢复 → 复盘
狩猎:假设 → 数据源 → 验证 → 规则化 → 自动化 → 紫队闭环

每环必须可回答「我看的是哪条日志?我证伪的是哪条假设?我下一步动作是什么?」

何时使用

| 场景 | 用 | 不用 | |------|----|----| | 写 Sigma/YARA 规则、调 SIEM | ✅ siem-and-edr | — | | 处理已发生入侵、取证 | ✅ incident-response | — | | 假设驱动狩猎 / 紫队演练 | ✅ threat-hunting | — | | ATT&CK 检测覆盖打分 | ✅ threat-hunting | — | | 设计应用层防御代码 | ❌ | [defending-applications](../defending-applications/SKILL.md) | | 渗透测试、写 PoC | ❌ | [securing-systems](../securing-systems/SKILL.md) (pentest/red-team) | | 威胁建模、IAM 架构 | ❌ | [architecting-security](../architecting-security/SKILL.md) | | 代码静态扫描胶水 | ❌ | [analyzing-security](../analyzing-security/SKILL.md) | | 云配置基线、K8s 加固 | ❌ | [securing-cloud-and-supply-chain](../securing-cloud-and-supply-chain/SKILL.md) |

联动

  • securing-systems/red-team:攻方 TTP 是本 skill 检测规则的设计输入。
  • securing-systems/threat-intel:IOC/CTI 投喂本 skill 的规则与狩猎假设。
  • architecting-security/threat-modeling:威胁模型的 detective control 在本 skill 落地。
  • analyzing-security:本 skill 产出的 detection-as-code 接入 CI 门禁。
  • automating-devops/observability:日志/指标/链路三支柱的安全维。

铁律

  1. 无噪不出闸 — 任何规则上线前必须有基线 + FP rate 测量;FP > 5% 直接打回调优,不准带病上线。
  2. 不证伪即假设 — 狩猎必须有可证伪的假设;找不到不是结论,是数据缺失或假设错。
  3. 取证不破坏现场 — 先采易失证据(内存/网络/进程),再动磁盘;写阻断器 + 哈希链 + 时间戳三件套必须齐。
  4. 检测即代码 — 规则进 git、有 unit test、过 CI、有 owner;改规则等同改生产代码。
  5. 闭环到 ATT&CK — 每条规则、每次事件、每次狩猎必须映射到 ATT&CK 技术 ID;无 ID 不归档。

输出约束

  • 规则示例必须给完整 frontmatter + detection + condition + 反例说明(为什么不这样写)。
  • 命令示例标注操作系统与权限要求(root / SYSTEM / 普通用户)。
  • 日志样例脱敏:IP 用 192.0.2.0/24、域名用 example.com、用户名用 ``。
  • 每条检测规则必须附 FP 来源清单与响应动作(containment / enrichment / kill)。
