Types

type Tracker

type Tracker struct {
	// contains filtered or unexported fields
}

Tracker implements a frequency tracker for a given input which is used to determine uninteresting input parameters which are not that interesting from fuzzing perspective for a template and target combination.

This is used to reduce the number of requests made during fuzzing for parameters that are less likely to give results for a rule.

func New

func New(maxTrackCount, paramOccurenceThreshold int) *Tracker

New creates a new frequency tracker with a given maximum number of params to track in LRU fashion with a max error threshold

func (*Tracker) Close

func (t *Tracker) Close()

func (*Tracker) IsParameterFrequent

func (t *Tracker) IsParameterFrequent(parameter, target, template string) bool

IsParameterFrequent checks if a parameter is frequently occuring in the input with no much results.

func (*Tracker) MarkParameter

func (t *Tracker) MarkParameter(parameter, target, template string)

MarkParameter marks a parameter as frequently occuring once.

The logic requires a parameter to be marked as frequently occuring multiple times before it's considered as frequently occuring.

func (*Tracker) UnmarkParameter

func (t *Tracker) UnmarkParameter(parameter, target, template string)

UnmarkParameter unmarks a parameter as frequently occuring. This carries more weight and resets the frequency counter for the parameter causing it to be checked again. This is done when results are found.
