Analyzing Network Traffic For Incidents is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Analyzes network traffic captures and flow data to identify adversary activity during security incidents, including command-and-control communications, lateral movement, data exfiltration, and exploitation attempts. Uses Wireshark, Zeek, and NetFlow analysis techniques. Activates for requests involving network traffic analysis, packet capture investigation, PCAP analysis, network forensics, C2 traffic detection, or exfiltration detection.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/api-reference.md` and `scripts/agent.py`).
It sits in Security, covering Red teaming and adversary simulation, Network security and Security operations. It works with Wireshark. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
sshFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use ssh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Analyzing Network Traffic For Incidents loads about 2.6k tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 775 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.
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); the scripts in this folder are not scanned.

Compile analysis into a structured report with evidence references:
| Term | Definition |
|---|---|
| PCAP (Packet Capture) | File format storing raw network packets captured from a network interface for offline analysis |
| Beaconing | Regular, periodic network connections from a compromised host to a C2 server, identifiable by consistent timing intervals |
| JA3/JA3S | TLS client and server fingerprinting method based on the ClientHello and ServerHello parameters; unique per application |
| NetFlow/IPFIX | Network traffic metadata (source, destination, ports, bytes, duration) collected by routers and switches without full packet capture |
| DNS Tunneling | Technique encoding data in DNS queries and responses to exfiltrate data or maintain C2 through DNS protocol |
| Network Tap | Hardware device that creates an exact copy of network traffic for monitoring without impacting network performance |
| Zeek Logs | Structured metadata logs generated by the Zeek network analysis framework covering connections, DNS, HTTP, SSL, and more |
Context: EDR detects a suspicious process on a workstation but cannot determine the volume of data exfiltrated. Network team provides PCAP from the full packet capture appliance covering the incident timeframe.

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill analyzing-network-traffic-for-incidents -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/analyzing-network-traffic-for-incidents, .gemini/skills/analyzing-network-traffic-for-incidents, .github/skills/analyzing-network-traffic-for-incidents and .opencode/skills/analyzing-network-traffic-for-incidents in your project.
Going by SKILL.md and its folder, Analyzing Network Traffic For Incidents needs Python for the scripts in its folder and the command-line tools its instructions call (ssh). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use ssh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Analyzing Network Traffic For Incidents is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 707 tokens, read only when the agent opens those files.
