DNS暴力破解
使用 d
和 w
标志为给定域或域列表强制创建子域名:
dnsx -silent -d facebook.com -w dns_worldlist.txt
blog.facebook.com
booking.facebook.com
api.facebook.com
analytics.facebook.com
beta.facebook.com
apollo.facebook.com
ads.facebook.com
box.facebook.com
alpha.facebook.com
apps.facebook.com
connect.facebook.com
c.facebook.com
careers.facebook.com
code.facebook.com
暴力破解使用单个或多个关键字输入锁定子域名,因为 d
或 w
标志支持文件或逗号分隔关键字输入:
dnsx -silent -d domains.txt -w jira,grafana,jenkins
grafana.1688.com
grafana.8x8.vc
grafana.airmap.com
grafana.aerius.nl
jenkins.1688.com
jenkins.airbnb.app
jenkins.airmap.com
jenkins.ahn.nl
jenkins.achmea.nl
jira.amocrm.com
jira.amexgbt.com
jira.amitree.com
jira.arrival.com
jira.atlassian.net
jira.atlassian.com
所有输入类型("列表"、"域名"、"字表")都接受来自标准输入的值。-list
标志默认为标准输入,但其他输入类型也可以通过添加"-"(破折号)作为参数来实现:
cat domains.txt | dnsx -silent -w jira,grafana,jenkins -d -
grafana.1688.com
grafana.8x8.vc
grafana.airmap.com
grafana.aerius.nl
jenkins.1688.com
jenkins.airbnb.app
jenkins.airmap.com
jenkins.ahn.nl
jenkins.achmea.nl
jira.amocrm.com
jira.amexgbt.com
jira.amitree.com
jira.arrival.com
jira.atlassian.net
jira.atlassian.com
使用基于占位符的单词表进行 DNS 暴力破解
$ cat tld.txt

al
bi
cg
dj
bs
dnsx -d google.FUZZ -w tld.txt -resp

通配符过滤
dnsx 的一大特点是能够处理基于 DNS 的多级通配符,而且只需极少的 DNS 请求即可完成。有时,所有子域名都会解析,这会导致输出中出现大量垃圾。dnsx处理这种情况的方法是跟踪有多少个子域名指向一个 IP,如果子域名的数量增加超过某个阈值,它就会在该 IP 的所有主机级别上反复检查通配符。
dnsx -l subdomain_list.txt -wd airbnb.com -o output.txt
Dnsx 作为库
您可以在 golang 程序中直接使用该库。以下代码片段是 golang 程序中的使用示例。请参阅此处了解详细的包配置和使用方法。
package main
import (
"fmt"
"github.com/projectdiscovery/dnsx/libs/dnsx"
)
func main() {
// Create DNS Resolver with default options
dnsClient, err := dnsx.New(dnsx.DefaultOptions)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
// DNS A question and returns corresponding IPs
result, err := dnsClient.Lookup("hackerone.com")
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
for idx, msg := range result {
fmt.Printf("%d: %s\n", idx+1, msg)
}
// Query
rawResp, err := dnsClient.QueryOne("hackerone.com")
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Printf("rawResp: %v\n", rawResp)
jsonStr, err := rawResp.JSON()
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(jsonStr)
return
}
📋 注释
- 默认情况下,dnsx检查A记录。
- 默认情况下,dnsx使用 Google、Cloudflare、Quad9解析器。
- 可以使用
r
标志加载自定义解析器列表。 - 域名 (
wd
) 输入必须用于通配符消除。 - 使用通配符过滤时不能使用 DNS 记录标记。
- DNS 解析 (
l
) 和 DNS 强制 (w
) 不能同时使用。 - VPN 运营商倾向于过滤高 DNS/UDP 流量,因此该工具可能会出现数据包丢失的情况
