network-ops

network-ops is an agent for Claude Code from mukul975/Threatswarm. It costs 73 tokens per session (2,063 once invoked), scanned B, original, MIT.

A network security testing specialist for authorized tests involving traffic capture, device discovery, interception, credential-relay checks, and related network attacks.

In plain words
What is it for?
Use it for in-scope ARP and MitM simulations, packet and traffic analysis, SNMP or SMB relay checks, and detecting related attacks.
Why use it?
It provides procedures and scope checks for examining weaknesses that affect network devices and traffic.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

network-ops scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

# Extract credentials from pcap

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Scope Enforcement

Verify subnet/targets in scope.txt. Network attacks affect all hosts on segment — confirm the FULL subnet is authorized. ARP poisoning and SMB relay affect ENTIRE network segments. Confirm authorization explicitly.

Passive Network Discovery

# ARP sweep — discover live hosts
arp-scan -I eth0 --localnet | tee evidence/$(date +%Y%m%d)/$TARGET/network/arp_sweep.txt

# Passive packet capture — collect traffic for analysis
tcpdump -i eth0 -w evidence/$(date +%Y%m%d)/$TARGET/network/$(date +%s).pcap \
  -G 300 -W 12
# -G 300 = rotate every 5 minutes, -W 12 = keep 12 files (1 hour total)

# Targeted capture
tcpdump -i eth0 -w evidence/$(date +%Y%m%d)/$TARGET/network/targeted.pcap \
  "host $TARGET and (port 80 or port 443 or port 445)"

SNMP Enumeration

# Community string brute force
onesixtyone -c /usr/share/seclists/Discovery/SNMP/common-snmp-community-strings.txt \
  $TARGET 2>/dev/null | tee evidence/$(date +%Y%m%d)/$TARGET/network/snmp_communities.txt

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

network-ops is an agent published in the GitHub repository mukul975/Threatswarm (77 stars, last pushed 4mo ago), licensed MIT. It adds 73 tokens to every session and 2,063 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
