    'http': 'http://127.0.0.1:8080',
    'https': 'http://127.0.0.1:8080'
}

# Minimum payload efficiency to display
minEfficiency = 90

# Request settings
delay = 0           # Default delay between requests
threadCount = 10    # Default thread count
timeout = 10        # Default request timeout

# Event handlers for payload generation
eventHandlers = {
    'ontoggle': ['details'],
    'onpointerenter': ['d3v', 'details', 'html', 'a'],
    'onmouseover': ['a', 'html', 'd3v']
}

# JavaScript functions for popups
functions = (
    '[8].find(confirm)', 'confirm()',
    '(confirm)()', 'co\\u006efir\\u006d()',
    '(prompt)``', 'a=prompt,a()'
)

# Built-in payloads for bruteforce mode
