SIGNAL-FLARE 🚨

Post-exploitation breach confirmation through honey-credential instrumentation

Detect credential theft with zero false positives.

SIGNAL-FLARE plants fake credentials in your application. When attackers steal and use them, you get instant alerts—no guessing, no noise, just ground truth.

🎯 The Problem

Traditional security tools tell you "something suspicious happened."
SIGNAL-FLARE tells you: "credentials were stolen and someone is using them right now."

Without SIGNAL-FLARE	With SIGNAL-FLARE
❌ Behavioral detection (maybe it's an attack?)	✅ Ground truth detection (definitely compromised)
❌ High false positive rate	✅ Zero false positives by design
❌ Alert fatigue	✅ Every alert is actionable
❌ Detection in days/weeks	✅ Detection in seconds

🚀 Quick Start (5 Minutes)

Option 1: Docker Compose (Easiest)

# Clone and start
git clone https://github.com/logesh-GIT001/signal-flare.git
cd signal-flare

# Generate secret and start listener
export FLARE_SECRET=$(openssl rand -hex 32)
docker-compose up -d

# Verify it's running
curl http://localhost:8080/health
# → {"status":"healthy"}

Option 2: Python CLI

# Install
pip install signal-flare

# Generate honey-credential
export FLARE_SECRET=$(openssl rand -hex 32)
signal-flare generate --type aws

Output:

# Fake AWS Credential
AWS_ACCESS_KEY_ID=AKIAF3A8D9C1B4E6
AWS_SECRET_ACCESS_KEY=s3SU0MhafXuK6wFTZakFx2AIty...
FLARE_ID=1767248654:3ea23854f39bf000a29d0f34eaf5679f...

Key insight: Legitimate code never touches honey-credentials, so ANY usage = confirmed breach.

🏢 Real-World Use Cases

Scenario 1: Kubernetes Microservices

# Inject honey-credentials during deployment
env:
  - name: DATABASE_URL
    value: postgresql://real_user:pass@db:5432/prod
  - name: BACKUP_DB_READONLY  # ← Honey-credential
    value: postgresql://fake_user:trap@db:5432/analytics

Result: When attacker compromises pod and tests credentials → instant alert.

Scenario 2: CI/CD Pipeline

# .github/workflows/deploy.yml
- name: Instrument with honey-credentials
  run: |
    signal-flare generate --type aws >> .env.production
    docker build --env-file .env.production .

Result: Every deployment gets fresh honey-credentials automatically.

Scenario 3: Lambda Functions

# Honey-credential sits unused in environment
BACKUP_AWS_KEY = os.environ['BACKUP_AWS_ACCESS_KEY_ID']

# Real work uses IAM role (secure)
s3 = boto3.client('s3')  # Uses IAM, not env vars

Result: If Lambda code is exfiltrated and attacker tests credentials → alert.

👉 See full deployment guide in USE_CASES.md

🎯 Why This Matters

Traditional Detection:

Step 1: Attacker breaks in
Step 2: Steals credentials
Step 3: Uses them for weeks/months  ← UNDETECTED
Step 4: Data exfiltrated
Step 5: Finally discovered (average: 277 days)

With SIGNAL-FLARE:

Step 1: Attacker breaks in
Step 2: Steals credentials
Step 3: Tests them
        └─ 🚨 ALERT (within seconds)
Step 4: Security team responds immediately

Mean Time to Detect: 277 days → 5 seconds

📦 Installation

CLI Tool

pip install signal-flare

Listener Service

docker-compose up -d

From Source

git clone https://github.com/logesh-GIT001/signal-flare.git
cd signal-flare/cli
pip install -e .

🔧 Configuration

Environment Variables

Variable	Description	Required	Default

`FLARE_LISTENER`	Listener URL	No	http://localhost:8080
`FLARE_TTL_HOURS`	Credential lifetime	No	24
`SIEM_WEBHOOK`	SIEM integration URL	No	-

Generate Secret

# Generate once, store securely (e.g., Vault, AWS Secrets Manager)
openssl rand -hex 32

🧪 Testing End-to-End

1. Start Listener

export FLARE_SECRET=$(openssl rand -hex 32)
docker-compose up -d

2. Generate Credential

signal-flare generate --type aws
# Copy the FLARE_ID from output

3. Simulate Attack

curl -X POST http://localhost:8080/flare \
  -H "Content-Type: application/json" \
  -d '{"flare_id":"PASTE_FLARE_ID","credential_type":"aws_access_key","action_attempted":"iam:ListUsers"}'

4. Check Logs

docker-compose logs listener
