C2 Beacon Analysis is an agent skill from wgpsec/AboutSecurity. C2 Beacon 配置提取与分析。当捕获到 Cobalt Strike/Sliver/Havoc 等 C2 框架的 Beacon 样本、内存 dump、或网络流量时使用。提取 C2 地址、通信协议、Malleable Profile、Watermark 等关键情报。红队视角：了解蓝队如何从 Beacon 提取 IOC 以改进 C2 OPSEC
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/cs-beacon-decrypt.md` and `references/modern-c2-analysis.md`).
It sits in Security. 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。

What it can do on your machine
Read from SKILL.md and the folder at commit db4573f. 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
Shell commands in SKILL.md call:
python3
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
C2 Beacon Analysis loads about 1.2k tokens when it runs, and up to ~7k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 121 words of instructions outside code blocks.
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.

Without a licence we can't republish the file, so here is its outline and opening line. It has 121 words (~1,217 tokens).
