How to use analyzing-cobaltstrike-malleable-c2-profiles on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add analyzing-cobaltstrike-malleable-c2-profiles

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills install mukul975/Anthropic-Cybersecurity-Skills/analyzing-cobaltstrike-malleable-c2-profiles

Fetches analyzing-cobaltstrike-malleable-c2-profiles from mukul975/Anthropic-Cybersecurity-Skills and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Overview

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 for detection: 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.

When to Use

When investigating security incidents that require analyzing cobaltstrike malleable c2 profiles

When building detection rules or threat hunting queries for this domain

When SOC analysts need structured procedures for this analysis type

When validating security monitoring coverage for related attack techniques

Prerequisites

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 deployment

PCAP analysis tools for traffic validation

Steps

Install libraries: pip install dissect.cobaltstrike or pip install pyMalleableC2

Parse profile with C2Profile.from_path("profile.profile")

Extract HTTP GET/POST block configurations (URIs, headers, parameters)

Identify user agent strings and spoof targets

Extract sleep time, jitter percentage, and DNS beacon settings

Analyze process injection settings (spawn-to, allocation technique)

Generate Suricata/Snort signatures from extracted network indicators

Compare profile against known threat actor profile collections

Extract staging URIs and payload delivery mechanisms

Produce detection report with IOCs and recommended network signatures
