Overview ¶
Package wildcarder provides a subdomain wildcard detection algorithm. It operates on the DNS records of the target domains. It can use the result file produced by "massdns -o Snl" to optimize the process and lower the number of DNS queries made.

Types ¶
type AnswerHash ¶
type AnswerHash struct {
Type resolvermt.RRtype
Hash uint64
}
AnswerHash is the type of an answer stored in the cache.
func HashAnswer ¶
func HashAnswer(answer DNSAnswer) AnswerHash
HashAnswer hashes a DNSAnswer and returns a AnswerHash.
type ClientDNS ¶
type ClientDNS struct {
// contains filtered or unexported fields
}
ClientDNS is a DNS client that implements the Resolver interface.
func NewClientDNS ¶
NewClientDNS creates a new ResolverDNS object to use with a Wildcarder object.
func (*ClientDNS) QueryCount ¶
QueryCount returns the number of DNS queries really performed.
type DNSAnswer ¶
type DNSAnswer struct {
Type resolvermt.RRtype
Answer string
}
DNSAnswer represents a DNS answer without the question.
type DNSCache ¶
type DNSCache struct {
// contains filtered or unexported fields
}
DNSCache represents a cache of DNS queries and answers.
func (*DNSCache) Add ¶
Add adds an answer to the DNS cache. The answer will be appended to the list of existing answers for a question if they already exist.
func (*DNSCache) Find ¶
func (c *DNSCache) Find(question string) []AnswerHash
Find returns the answers for a given DNS query from the cache. The list of answers returned can be empty if the question is in the cache but no results were found, or nil if the question is not in the cache.
type Option ¶
type Option interface {
// contains filtered or unexported methods
}
Option configures a wildcarder.
func WithPreCache ¶
WithPreCache returns an option that provides a pre-populated DNS cache used to optimize the number of DNS queries made during the wildcard detection phase. This DNS cache is not trusted, and the results will be validated as needed using trusted resolvers.
func WithResolver ¶
WithResolver returns an option that provides a custom resolver to use while performing wildcard detection.
type QuestionHash ¶
type QuestionHash uint64
QuestionHash is the type of the question stored in the cache.
func HashQuestion ¶
func HashQuestion(question string) QuestionHash
HashQuestion hashes a question and returns a QuestionHash.
type Resolver ¶
Resolver resolves domain names A and AAAA records and returns the DNS answers found.
type Wildcarder ¶
type Wildcarder struct {
// contains filtered or unexported fields
}
Wildcarder filters out wildcard subdomains from a list.
func New ¶
func New(threadCount int, testCount int, options ...Option) *Wildcarder
New returns a Wildcarder object used to filter out wildcards.
func (*Wildcarder) Current ¶
func (wc *Wildcarder) Current() int
Current returns the current number of domains that have been processed.
func (*Wildcarder) Filter ¶
func (wc *Wildcarder) Filter(r io.Reader) (domains, roots []string)
Filter reads subdomains from a reader and returns a list of domains that are not wildcards, along with the wildcard subdomain roots found.
func (*Wildcarder) QueryCount ¶
func (wc *Wildcarder) QueryCount() int
QueryCount returns the total number of DNS queries made so far to detect wildcards.
func (*Wildcarder) SetPreCache ¶
func (wc *Wildcarder) SetPreCache(precache *DNSCache)
SetPreCache sets the precache after the Wildcarder object has been created.
