Strix includes a full HTTP proxy for traffic interception and manipulation.

Capabilities

  • Request capture — Log all HTTP traffic from the browser
  • Request replay — Repeat requests with modifications
  • HTTPQL filtering — Query traffic with Caido-style syntax
  • Scope management — Filter by domain or path patterns
  • Sitemap generation — Visualize discovered attack surface

Workflow

  1. Browse the target with the browser tool
  2. List captured requests with filters
  3. Replay interesting requests with modified parameters
  4. Validate vulnerabilities with crafted payloads

HTTPQL Examples

# POST requests to API endpoints
req.method.regex:"POST" AND req.path.cont:"/api/"

# Requests with specific response codes
resp.code.gte:400

# Filter by host
req.host.regex:".*api.example.com"

Scope Management

Create scopes to focus on specific parts of the application:
# Allowlist
["api.example.com", "*.example.com"]

# Denylist (exclude static assets)
["*.gif", "*.jpg", "*.png", "*.css", "*.js"]
