Consolidate 22 sibling repos into layered organism structure 
Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):

- brain/        LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
                dispatch, A51 channels, and the OSINT cluster
- knowledge/    LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
                MITRE ATT&CK data
- reference/    defensive threat-reference (C3, shhbruh doc) + AdaYaml parser

License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.

Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

CobaltStrike Malleable C2 Profile Analysis API Reference

Installation

pip install dissect.cobaltstrike
pip install 'dissect.cobaltstrike[full]'   # With PCAP support
pip install pyMalleableC2                   # Alternative parser

dissect.cobaltstrike API

Parse Beacon Configuration

from dissect.cobaltstrike.beacon import BeaconConfig

bconfig = BeaconConfig.from_path("beacon.bin")
print(hex(bconfig.watermark))     # 0x5109bf6d
print(bconfig.protocol)           # https
print(bconfig.version)            # BeaconVersion(...)
print(bconfig.settings)           # Full config dict

Parse Malleable C2 Profile

from dissect.cobaltstrike.c2profile import C2Profile

profile = C2Profile.from_path("amazon.profile")
config = profile.as_dict()
print(config["useragent"])
print(config["http-get.uri"])
print(config["sleeptime"])

PCAP Analysis

# Extract beacons from PCAP
beacon-pcap --extract-beacons traffic.pcap

# Decrypt traffic with private key
beacon-pcap -p team_server.pem traffic.pcap --beacon beacon.bin

pyMalleableC2 API

from malleableC2 import Profile

profile = Profile.from_file("amazon.profile")
print(profile.sleeptime)
print(profile.useragent)
print(profile.http_get.uri)
print(profile.http_post.uri)

Key Profile Settings

Setting Description Detection Value
sleeptime Callback interval (ms) Low values = aggressive beaconing
jitter Sleep randomization % Timing analysis evasion
useragent HTTP User-Agent string Network signature
http-get.uri GET request URI path URI-based detection
http-post.uri POST request URI path URI-based detection
spawnto_x86 32-bit spawn process Process creation detection
spawnto_x64 64-bit spawn process Process creation detection
pipename Named pipe pattern Named pipe monitoring
dns_idle DNS idle IP address DNS beacon detection
watermark License watermark Operator attribution

Suricata Rule Format

alert http $HOME_NET any -> $EXTERNAL_NET any (
  msg:"MALWARE CobaltStrike C2 URI";
  flow:established,to_server;
  http.uri; content:"/api/v1/status";
  http.header; content:"User-Agent: Mozilla/5.0";
  sid:9000001; rev:1;
)

CLI Usage

python agent.py --input profile.profile --output report.json
python agent.py --input parsed_config.json --output report.json
