# Analyzing Cobaltstrike Malleable C2 Profiles


## Genel Bakış

Cobalt Strike Malleable C2 profiles are domain-specific language scripts that customize how Beacon communicates with the team server, defining HTTP request/response transformations, sleep intervals, jitter values, user agents, URI paths, and process injection behavior. Threat actors use malleable profiles to disguise C2 traffic as legitimate services (Amazon, Google, Slack). Analyzing these profiles reveals network indicators forDetect URI patterns, HTTP headers, POST/GET transforms, DNS settings, and process injection techniques. The `dissect.cobaltstrike` library can parse both profile files and extract configurations from beacon payloads, while `pyMalleableC2` provides AST-based parsing using Lark grammar for programmatic profile manipulation and validation.


## Ne Zaman Kullanılır

- investigating yaparken security incidents that require analyzing cobaltstrike malleable c2 profiles
- building yaparken Tespit rules or threat hunting queries for this domain
- SOC yaparken: analysts need structured procedures for this analysis type
- validating yaparken security monitoring coverage for related attack techniques

## Ön Gereksinimler

- Python 3.9+ with `dissect.cobaltstrike` and/or `pyMalleableC2`
- Sample Malleable C2 profiles (available from public repositories)
- Understanding of HTTP protocol and Cobalt Strike beacon communication model
- Network monitoring tools (Suricata/Snort) for signature Dağıt:ment
- PCAP analysis tools for traffic validation

## Adımlar

1. Install libraries: `pip install dissect.cobaltstrike` or `pip install pyMalleableC2`
2. Parse profile with `C2Profile.from_path("profile.profile")`
3. Extract HTTP GET/POST block configurations (URIs, headers, parameters)
4. Identify user agent strings and spoof targets
5. Extract sleep time, jitter percentage, and DNS beacon settings
6. Analyze process injection settings (spawn-to, allocation technique)
7. Generate Suricata/Snort signatures from extracted network indicators
8. Compare profile against known threat actor profile collections
9. Extract staging URIs and payload delivery mechanisms
10. Produce Tespit report with IOCs and recommended network signatures

## Expected Output

A JSON report containing extracted C2 URIs, HTTP headers, user agents, sleep/jitter settings, process injection config, spawned process paths, DNS settings, and generated Suricata-compatible Tespit rules.
