K8s Sidecar Attack

Kubernetes Sidecar 容器流量劫持与敏感信息窃取。当目标 Pod 存在 Istio/Envoy/Linkerd sidecar、题目提到'隐形旁观者'或'共享网络'、或需要从 Pod 内部嗅探流量时使用。覆盖 tcpdump 抓包、sidecar 明文流量捕获、共享网络命名空间利用。只要在 K8s Pod 中发现有 sidecar 或多容器共存的迹象，就应使用此技能

What it does

K8s Sidecar Attack is an agent skill from wgpsec/AboutSecurity. Kubernetes Sidecar 容器流量劫持与敏感信息窃取。当目标 Pod 存在 Istio/Envoy/Linkerd sidecar、题目提到'隐形旁观者'或'共享网络'、或需要从 Pod 内部嗅探流量时使用。覆盖 tcpdump 抓包、sidecar 明文流量捕获、共享网络命名空间利用。只要在 K8s Pod 中发现有 sidecar 或多容器共存的迹象，就应使用此技能

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Container orchestration. It works with Kubernetes. The repository describes itself as: Everything for pentest. | 渗透测试知识库，以 AI Agent 可执行的格式沉淀安全方法论。

Workflow steps

检测 Sidecar
流量抓包
分析结果

What it can do on your machine

Read from SKILL.md and the folder at commit d428372. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

K8s Sidecar Attack loads about 634 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~53
When it runs · the whole SKILL.md, loaded when a task matches: ~634

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 93 words (~634 tokens).

“同一 Pod 内的所有容器共享网络命名空间——这是 K8s 的设计决定，也是攻击者的福音。Sidecar 容器（如 Istio Envoy）发送的流量可以被同 Pod 的任何容器通过 tcpdump 直接抓取，因为它们共享同一张网卡。”
