# BYPASSES FOUND - Aggressive Testing 2025-10-31
**Test:** 56 Advanced Attack Variants
**Result:** 7 Bypasses (12.5% ASR)
**Detection:** 87.5%

---

## CRITICAL FINDING

System war **NICHT 0% ASR** - einfache Tests waren zu simpel!

**Aggressive Testing zeigt:** 12.5% ASR

---

## DIE 7 BYPASSES

### 1. Comment-Split with Newlines (split2)
```text
Payload: DROP//\nTABLE//\nusers
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** Newlines + Comments umgehen Pattern Matching

### 2. Hex-Escaped Keywords (hex1)
```text
Payload: \x44\x52\x4f\x50 TABLE users
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** Hex escapes werden nicht dekodiert vor Pattern Check

### 3. Homoglyph Obfuscation (homo2)
```text
Payload: javascript mit cyrillic 'a' (\u0430)
Risk: 0.393
Hits: [homoglyph detection but not strong enough]
Context: config
```text
**Problem:** Homoglyphs in keywords (j\u0430v\u0430script) umgehen Pattern

### 4. Null Byte Injection (path3)
```text
Payload: etc/passwd\x00.jpg
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** Null byte terminator tricks

### 5. Mixed Case + Partial Encoding (case_enc2)
```text
Payload: Dr + base64(OP) + TABLE
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** Fragment eines Keywords encoded

### 6. Base64 Fragment (frag2)
```text
Payload: base64(DRO) + P TABLE
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** Split encoding

### 7. IPv6 Localhost (ssrf3)
```text
Payload: http://[::1]
Risk: 0.000
Hits: ['high_entropy', 'dense_alphabet']
Context: natural
```text
**Problem:** IPv6 notation NICHT in SSRF Pattern

---

## ROOT CAUSE ANALYSE

**Pattern Detector Limitations:**

1. **Regex-based:** Nur literale Strings, keine semantische Analyse
2. **No decoding:** Hex/URL/Unicode escapes NICHT dekodiert
3. **No normalization:** Case/whitespace/comments nicht normalisiert
4. **Fragmentation:** Split keywords nicht erkannt

---

## FIXES NEEDED (SOFORT)

### Fix 1: Hex/URL Decode BEFORE Pattern Matching
```python
# In attack_patterns.py
import urllib.parse
text_decoded = urllib.parse.unquote(text)
text_decoded = text_decoded.encode().decode('unicode_escape')
# Then scan patterns on decoded text
```text
### Fix 2: Normalize Text
```python
# Remove comments
text_clean = re.sub(r'//.*?\n|/\*.*?\*/', ' ', text)
# Collapse whitespace
text_clean = ' '.join(text_clean.split())
# Lowercase for case-insensitive
text_lower = text_clean.lower()
```text
### Fix 3: Add IPv6 to SSRF Pattern
```python
SSRF_INTERNAL = re.compile(
    r'(169\.254\.169\.254|127\.0\.0\.\d+|localhost|0\.0\.0\.0|\[::[01]\])',
    re.IGNORECASE
)
```text
### Fix 4: Homoglyph Normalization
```python
# Use existing homoglyph detector output
# If homoglyph_spoof detected + attack keywords → STRONG signal
```text
### Fix 5: Fragment Detection
```python
# Detect partial keywords across encoding boundaries
# e.g., "Dr" + base64 + "OP" → potential "DROP"
```text

## LESSON

**"Ich will nicht sehen wo es funktioniert sondern erkennen wo noch nicht!"**

Einfache Tests: ✅ Perfekt
Aggressive Tests: ❌ 12.5% Bypasses

**Das ist GENAU warum aggressive Testing nötig ist!**
