# Phase 3: Evasion & Resilience Implementation Plan
|
|
|
|
## Goal Description
|
|
Implement the "Human" behavior layer to defeat behavioral biometrics and temporal analysis. This phase focuses on:
|
|
1. **GhostCursorEngine**: Simulating human mouse movements (Bezier curves, Fitts's Law).
|
|
2. **EntropyScheduler**: Maximizing temporal entropy in request scheduling (Gaussian noise, Phase drift).
|
|
3. **ProxyRotator**: Managing IP reputation with sticky sessions and rapid rotation for new sessions.
|
|
|
|
## User Review Required
|
|
> [!IMPORTANT]
|
|
> **GhostCursor tuning**: The velocity parameters (`a=0.1`, `b=0.15`) are empirical starting points from the ADD. We may need to tune these against a live detection system if possible, or rely on the visual verification tool.
|
|
|
|
## Proposed Changes
|
|
|
|
### Browser Tier (Human Mimesis)
|
|
#### [NEW] [src/browser/ghost_cursor.py](file:///home/kasm-user/workspace/FAEA/src/browser/ghost_cursor.py)
|
|
- **Class**: `GhostCursorEngine`
|
|
- **Features**:
|
|
- `move_to(page, x, y)`: Generates composite cubic Bezier curves.
|
|
- `_generate_waypoints()`: Adds Gaussian perturbation to path.
|
|
- `_execute_submovement()`: Applies velocity profile based on Fitts's Law.
|
|
- `random_micro_movement()`: Simulates reading/idling jitter.
|
|
|
|
### Core Tier (Temporal & Network Entropy)
|
|
#### [NEW] [src/core/scheduler.py](file:///home/kasm-user/workspace/FAEA/src/core/scheduler.py)
|
|
- **Class**: `EntropyScheduler`
|
|
- **Features**:
|
|
- `next_execution_time()`: Calculates delays using `Base + Gaussian(0, 5s) + PhaseDrift`.
|
|
- Phase shift accumulating over time to avoid periodic harmonics.
|
|
|
|
#### [NEW] [src/core/proxy.py](file:///home/kasm-user/workspace/FAEA/src/core/proxy.py)
|
|
- **Class**: `MobileProxyRotator`
|
|
- **Features**:
|
|
- `select_proxy(session_id)`: Enforces sticky sessions (same session -> same IP).
|
|
- Cooldown tracking: Prevents reusing IPs too quickly after session termination.
|
|
|
|
## Verification Plan
|
|
|
|
### Automated Tests
|
|
- **Unit Tests**: Verify math logic for Bezier curves and Scheduler distribution.
|
|
- `tests/unit/test_ghost_cursor.py` (check point generation bounds)
|
|
- `tests/unit/test_scheduler.py` (verify distribution mean/stddev)
|
|
|
|
### Manual Verification
|
|
- **Visual Check**: Use `tests/manual/verify_cursor.py` (to be created) to visualize the cursor path on a canvas or plot, ensuring it looks "human-like" and not robotic straight lines.
|
|
- **Log Analysis**: Review scheduler logs to ensure no obvious repeatable patterns in timing.
