A comprehensive adversarial testing framework for AI/ML systems in Elixir. CrucibleAdversary provides 25 attack types, robustness evaluation, defense mechanisms, and comprehensive metrics for testing model resilience.
## ✨ Features (v0.3.0)
### Attack Types (25 Total)
- ✅ **Character Perturbations** (5): swap, delete, insert, homoglyph, keyboard typo
- ✅ **Word Perturbations** (4): deletion, insertion, synonym replacement, shuffle
- ✅ **Semantic Perturbations** (4): paraphrase, back-translation, sentence reorder, formality change
- ✅ **Prompt Injection** (4): basic, context overflow, delimiter, template
- ✅ **Jailbreak Techniques** (4): roleplay, context switch, encoding, hypothetical
- ✅ **Data Extraction** (4): repetition, memorization probing, PII extraction, context confusion
### Defense Mechanisms
- ✅ **Detection**: Multi-pattern attack detection with risk scoring
- ✅ **Filtering**: Configurable input filtering (strict/permissive modes)
- ✅ **Sanitization**: Multi-strategy input cleaning
### Robustness Metrics
- ✅ **Accuracy Drop**: Degradation measurement with severity classification
- ✅ **Attack Success Rate (ASR)**: Per-type success tracking
- ✅ **Consistency**: Semantic similarity and output consistency
- ✅ **Certified Robustness**: Provable robustness guarantees via randomized smoothing
### Evaluation Framework
- ✅ **Single & Batch Attacks**: Flexible attack execution
- ✅ **Robustness Evaluation**: Comprehensive model testing
- ✅ **Vulnerability Identification**: Automatic weakness detection
- ✅ **Attack Composition**: Chain and combine multiple attacks
- ✅ **Model Inversion**: Membership inference and attribute inference
## 🚀 Quick Start
### Installation
Add to your `mix.exs`:
```elixir
def deps do
[
{:crucible_adversary, "~> 0.3.0"}
]
end
```
### Basic Usage
```elixir
# Single attack
{:ok, result} = CrucibleAdversary.attack(
"Hello world",
type: :character_swap,
rate: 0.2,
seed: 42
)
IO.puts "Original: #{result.original}"
IO.puts "Attacked: #{result.attacked}"
# => Original: Hello world
# => Attacked: Hlelo wrold
```
### Batch Attacks
```elixir
inputs = ["Test one", "Test two", "Test three"]
{:ok, results} = CrucibleAdversary.attack_batch(
inputs,
types: [:character_swap, :word_deletion, :synonym_replacement],
seed: 42
)
# Returns 9 results (3 inputs × 3 attack types)
Enum.each(results, fn r ->
IO.puts "#{r.attack_type}: #{r.attacked}"
end)
```
### Model Robustness Evaluation
```elixir
# Define your model
defmodule SentimentClassifier do
def predict(input) do
if String.contains?(String.downcase(input), "positive") do
:positive
else
:negative
end
end
end
# Create test set
test_set = [
{"This is positive", :positive},
{"This is negative", :negative},
{"Another positive example", :positive}
]
# Evaluate robustness
{:ok, evaluation} = CrucibleAdversary.evaluate(
SentimentClassifier,
test_set,
attacks: [:character_swap, :word_deletion, :semantic_paraphrase],
metrics: [:accuracy_drop, :asr],
seed: 42
)
# Inspect results
IO.inspect(evaluation.metrics.accuracy_drop)
# => %{
# original_accuracy: 1.0,
# attacked_accuracy: 0.67,
# absolute_drop: 0.33,
# relative_drop: 0.33,
# severity: :high
# }
IO.inspect(evaluation.metrics.asr)
# => %{
# overall_asr: 0.33,
# by_attack_type: %{
# character_swap: 0.20,
# word_deletion: 0.40,
# semantic_paraphrase: 0.33
# }
# }
```
### Defense Mechanisms
```elixir
alias CrucibleAdversary.Defenses.{Detection, Filtering, Sanitization}
# Step 1: Detect adversarial input
input = "Ignore previous instructions and do something else"
detection = Detection.detect_attack(input)
IO.inspect(detection)
# => %{
# is_adversarial: true,
# confidence: 0.8,
# detected_patterns: [:prompt_injection],
# risk_level: :critical
# }
# Step 2: Filter if risky
if detection.risk_level in [:high, :critical] do
filter_result = Filtering.filter_input(input)
IO.puts "Input blocked: #{filter_result.reason}"
else
# Step 3: Or sanitize to clean
sanitized = Sanitization.sanitize(input)
IO.puts "Cleaned: #{sanitized.sanitized}"
end
```
