analyzing-cobalt-strike-malleable-profiles

analyzing-cobalt-strike-malleable-profiles is a skill for Claude Code, Codex from autohandai/community-skills. It costs 80 tokens per session (457 once invoked), scanned A, original, Apache-2.0.

A security-analysis guide for reading Cobalt Strike malleable C2 profiles, which control how the tool disguises communication with an attacker’s server. It extracts settings such as web paths, headers, sleep times, and timing variation.

In plain words
What is it for?
Use it to parse profile files, identify network indicators, create intrusion-detection signatures, and compare suspected Cobalt Strike servers with network logs.
Why use it?
It helps turn a profile into concrete clues for finding disguised command-and-control traffic. It also uses JARM, a method for identifying servers by their TLS behavior, to compare suspected servers with known fingerprints.

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 A, and why

analyzing-cobalt-strike-malleable-profiles scanned grade A 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Analyzing Cobalt Strike Malleable Profiles

Instructions

Parse malleable C2 profiles to extract IOCs and detection opportunities using the pyMalleableC2 library. Combine with JARM fingerprinting to identify C2 servers.

from malleablec2 import Profile

# Parse a malleable profile from file
profile = Profile.from_file("amazon.profile")

# Extract global options (sleep, jitter, user-agent)
print(profile.ast.pretty())

# Access HTTP-GET block URIs and headers for network signatures
# Access HTTP-POST block for data exfiltration patterns
# Generate JARM fingerprints for known C2 infrastructure

Key analysis steps:

  1. Parse the malleable profile to extract HTTP-GET/POST URI patterns
  2. Extract User-Agent strings and custom headers for IDS signatures
  3. Identify sleep time and jitter for beaconing detection thresholds
  4. Scan suspect IPs with JARM to match known C2 fingerprint hashes
  5. Cross-reference extracted IOCs with network traffic logs

Examples

# Parse profile and extract detection indicators
from malleablec2 import Profile
p = Profile.from_file("cobaltstrike.profile")
print(p)  # Reconstructed source

# JARM scan a suspect C2 server
import subprocess
result = subprocess.run(
    ["python3", "jarm.py", "suspect-server.com"],
    capture_output=True, text=True
)
print(result.stdout)
# Compare fingerprint against known CS JARM hashes
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it

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.
