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: Reverse Engineering Ransomware Encryption
|
|
|
|
## Cryptographic Algorithm Constants
|
|
|
|
| Algorithm | Signature | Description |
|
|
|-----------|-----------|-------------|
|
|
| AES | S-Box starting `0x63 0x7C 0x77` | AES Rijndael substitution box |
|
|
| RSA | DER `0x30 0x82` prefix | ASN.1 RSA key structure |
|
|
| ChaCha20/Salsa20 | `expand 32-byte k` | Stream cipher constant |
|
|
| RC4 | Sequential 0-255 state | Key scheduling algorithm init |
|
|
|
|
## Encryption Analysis Techniques
|
|
|
|
| Technique | Tool | Purpose |
|
|
|-----------|------|---------|
|
|
| Entropy analysis | `ent`, Python | Detect encrypted regions |
|
|
| Constant scanning | IDA/Ghidra YARA | Find crypto implementations |
|
|
| API tracing | x64dbg, Frida | Trace CryptEncrypt/BCrypt calls |
|
|
| Key extraction | Volatility3 | Dump keys from memory |
|
|
|
|
## Ransomware Encryption Patterns
|
|
|
|
| Pattern | Indicator |
|
|
|---------|-----------|
|
|
| Full encryption | Entropy > 7.9 across entire file |
|
|
| Intermittent | High entropy blocks with gaps |
|
|
| Header-only | First N bytes encrypted, rest plain |
|
|
| Appended metadata | File larger than original (key/IV at end) |
|
|
|
|
## Common Ransomware Crypto
|
|
|
|
| Family | Algorithm | Key Mgmt |
|
|
|--------|-----------|----------|
|
|
| LockBit 3.0 | AES-256-CBC + RSA-2048 | Per-file AES key, RSA-encrypted |
|
|
| BlackCat/ALPHV | ChaCha20 + RSA-4096 | Rust implementation |
|
|
| Royal | AES-256-CBC + RSA-2048 | Intermittent encryption |
|
|
| Akira | ChaCha20 | Partial file encryption |
|
|
|
|
## Python Libraries
|
|
|
|
| Library | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| `hashlib` | stdlib | SHA256 hashing |
|
|
| `struct` | stdlib | Binary data parsing |
|
|
| `re` | stdlib | Pattern extraction |
|
|
| `math` | stdlib | Shannon entropy calculation |
