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.

API Reference: Performing DNS Tunneling Detection
scapy (DNS Packet Analysis)
from scapy.all import rdpcap, DNS, DNSQR, DNSRR, sniff
# Read from PCAP
packets = rdpcap("traffic.pcap")
for pkt in packets:
if pkt.haslayer(DNSQR):
qname = pkt[DNSQR].qname.decode()
qtype = pkt[DNSQR].qtype # 1=A, 16=TXT, 28=AAAA
# Live capture
def dns_callback(pkt):

Shannon Entropy Calculation
import math
from collections import Counter
def shannon_entropy(data):
counter = Counter(data)
length = len(data)
return -sum((c/length) * math.log2(c/length)
for c in counter.values())
# Normal domain: ~2.5-3.5 bits
# DNS tunnel: ~4.0-5.0 bits
DNS Tunneling Indicators
| Indicator | Threshold | Rationale |
|---|---|---|
| Subdomain entropy | > 3.8 | Encoded/encrypted data |
| Query length | > 50 chars | Payload in subdomain |
| TXT queries/domain | > 20/hour | Data channel |
| Unique subdomains | > 50/parent | Encoded sessions |
| Digit ratio | > 0.4 | Base64/hex encoding |
Common DNS Tunnel Tools
| Tool | Encoding | Record Types |
|---|---|---|
| iodine | Base128 | NULL, TXT, CNAME |
| dnscat2 | Hex/CNAME | TXT, MX, CNAME |
| dns2tcp | Base64 | TXT, KEY |
