Red Team Scanner¶

OxideShield™ includes a powerful red team scanner for automated security testing of LLM endpoints. The scanner probes your LLM APIs with known attack patterns to identify vulnerabilities before attackers do.

Quick Start¶

# Basic scan with built-in probes
oxideshield scan --target https://api.example.com/v1/chat

# With API authentication
oxideshield scan \
  --target https://api.anthropic.com/v1/messages \
  --api-key $ANTHROPIC_API_KEY \
  --model claude-3-sonnet

# Full scan with all probe categories
oxideshield scan \
  --target https://api.example.com/v1/chat \
  --categories prompt_injection,jailbreak,system_leak \
  --concurrency 10 \
  --output report.json \
  --format json

  category: prompt_injection
  severity: high
  payload: |
    [INTERNAL ADMIN]

          fi

GitLab CI¶

llm-security-scan:
  stage: security
  script:
    - oxideshield scan
        --target $LLM_ENDPOINT
        --api-key $LLM_API_KEY
        --format json
        --output gl-sast-report.json
  artifacts:
    reports:
      sast: gl-sast-report.json

Exit Codes¶

Code	Meaning
`0`	No critical vulnerabilities found
`1`	Critical vulnerabilities detected
`2`	Scan failed (connection error, invalid config)

Best Practices¶

1. Regular Scanning¶

Schedule daily scans to catch regressions:

# Cron job for daily scans
0 2 * * * oxideshield scan --target $URL --output /var/log/llm-scan-$(date +%Y%m%d).json

2. Progressive Testing¶

Start with low severity, increase over time:

# Week 1: Critical only
oxideshield scan --target $URL --min-severity critical

# Week 2: High and above
oxideshield scan --target $URL --min-severity high

# Week 3+: Full scan
oxideshield scan --target $URL --min-severity low

3. Combine with Guards¶

Use scan results to configure guards:

# Scan to identify vulnerabilities
oxideshield scan --target $URL --format json --output findings.json

# Configure guards based on findings
oxideshield init --from-scan findings.json

Troubleshooting¶

Target Not Reachable¶

# Check connectivity
curl -I https://api.example.com/v1/chat

# Check with verbose output
oxideshield scan --target $URL --verbose

Authentication Failures¶

# Verify API key
oxideshield scan --target $URL --api-key $KEY --verbose

# Check Authorization header format
# Default: "Authorization: Bearer {key}"

Timeout Issues¶

# Increase timeout for slow endpoints
oxideshield scan --target $URL --timeout 60

# Reduce concurrency if rate limited
oxideshield scan --target $URL --concurrency 2
