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.

# Analyzing TLS Certificate Transparency Logs
|
|
|
|
|
|
## When to Use
|
|
|
|
- When investigating security incidents that require analyzing tls certificate transparency logs
|
|
- 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
|
|
|
|
- Familiarity with security operations concepts and tools
|
|
- Access to a test or lab environment for safe execution
|
|
- Python 3.8+ with required dependencies installed
|
|
- Appropriate authorization for any testing activities
|
|
|
|
## Instructions
|
|
|
|
Query crt.sh Certificate Transparency database to find certificates issued for
|
|
domains similar to your organization's brand, detecting phishing infrastructure.
|
|
|
|
```python
|
|
from pycrtsh import Crtsh
|
|
|
|
c = Crtsh()
|
|
# Search for certificates matching a domain
|
|
certs = c.search("example.com")
|
|
for cert in certs:
|
|
print(cert["id"], cert["name_value"])
|
|
|
|
# Get full certificate details
|
|
details = c.get(certs[0]["id"], type="id")
|
|
```
|
|
|
|
Key analysis steps:
|
|
1. Query crt.sh for all certificates matching your domain pattern
|
|
2. Identify certificates with typosquatting variations (Levenshtein distance)
|
|
3. Flag certificates from unexpected CAs
|
|
4. Monitor for wildcard certificates on suspicious subdomains
|
|
5. Cross-reference with known phishing infrastructure
|
|
|
|
## Examples
|
|
|
|
```python
|
|
from pycrtsh import Crtsh
|
|
c = Crtsh()
|
|
certs = c.search("%.example.com")
|
|
for cert in certs:
|
|
print(f"Issuer: {cert.get('issuer_name')}, Domain: {cert.get('name_value')}")
|
|
```
