即时可用的漏洞评估和渗透测试设置。从任何地方运行完整的渗透测试,拥有 20 多种工具和功能,从侦察到报告。我们不取代渗透测试人员 - 我们开发定制工具、检测和利用模块,让他们有更多时间深入挖掘、弹出 shell 并享受乐趣。

基本信息

域名系统(DNS) 充当互联网的目录,允许用户通过易记的域名(如 google.com 或 facebook.com)访问网站,而不是数字的互联网协议(IP)地址。通过将域名翻译为 IP 地址,DNS 确保 Web 浏览器可以快速加载互联网资源,简化我们在线世界中的导航。

默认端口: 53

PORT     STATE SERVICE  REASON
53/tcp   open  domain  Microsoft DNS 6.1.7601 (1DB15D39) (Windows Server 2008 R2 SP1)
5353/udp open  zeroconf udp-response
53/udp   open  domain  Microsoft DNS 6.1.7601 (1DB15D39) (Windows Server 2008 R2 SP1)

不同的DNS服务器

  • DNS根服务器:这些位于DNS层次结构的顶部,管理顶级域,并仅在较低级别服务器不响应时介入。互联网名称分配和编号机构(ICANN)监督它们的运作,全球共有13个。

  • 权威域名服务器:这些服务器对其指定区域的查询拥有最终决定权,提供明确的答案。如果它们无法提供响应,查询将升级到根服务器。

  • 非权威域名服务器:这些服务器没有对DNS区域的所有权,它们通过查询其他服务器收集域信息。

  • 缓存DNS服务器:这种类型的服务器会记住先前查询的答案一段时间,以加快未来请求的响应时间,缓存持续时间由权威服务器决定。

  • 转发服务器:扮演简单角色的转发服务器只是将查询转发到另一个服务器。

  • 解析器:集成在计算机或路由器中,解析器在本地执行名称解析,不被视为权威。

枚举

横幅抓取

DNS中没有横幅,但您可以获取version.bind. CHAOS TXT的魔术查询,这将适用于大多数BIND域名服务器。 您可以使用dig执行此查询:

dig version.bind CHAOS TXT @DNS

还可以使用nmap脚本获取横幅:

--script dns-nsid

任意记录

ANY 记录将要求 DNS 服务器返回其愿意披露的所有可用条目。

dig any victim.com @<DNS_IP>

区域传送

该过程简称为异步完整传送区域(AXFR)。

dig axfr @<DNS_IP> #Try zone transfer without domain
dig axfr @<DNS_IP> <DOMAIN> #Try zone transfer guessing the domain
fierce --domain <DOMAIN> --dns-servers <DNS_IP> #Will try toperform a zone transfer against every authoritative name server and if this doesn'twork, will launch a dictionary attack

更多信息

dig ANY @<DNS_IP> <DOMAIN>     #Any information
dig A @<DNS_IP> <DOMAIN>       #Regular DNS request
dig AAAA @<DNS_IP> <DOMAIN>    #IPv6 DNS request
dig TXT @<DNS_IP> <DOMAIN>     #Information
dig MX @<DNS_IP> <DOMAIN>      #Emails related
dig NS @<DNS_IP> <DOMAIN>      #DNS that resolves that name
dig -x 192.168.0.2 @<DNS_IP>   #Reverse lookup
dig -x 2a00:1450:400c:c06::93 @<DNS_IP> #reverse IPv6 lookup

#Use [-p PORT]  or  -6 (to use ivp6 address of dns)

自动化

for sub in $(cat <WORDLIST>);do dig $sub.<DOMAIN> @<DNS_IP> | grep -v ';\|SOA' | sed -r '/^\s*$/d' | grep $sub | tee -a subdomains.txt;done

dnsenum --dnsserver <DNS_IP> --enum -p 0 -s 0 -o subdomains.txt -f <WORDLIST> <DOMAIN>

使用 nslookup

nslookup
> SERVER <IP_DNS> #Select dns server
> 127.0.0.1 #Reverse lookup of 127.0.0.1, maybe...
> <IP_MACHINE> #Reverse lookup of a machine, maybe...

有用的metasploit模块

auxiliary/gather/enum_dns #Perform enumeration actions

有用的 nmap 脚本

#Perform enumeration actions
nmap -n --script "(default and *dns*) or fcrdns or dns-srv-enum or dns-random-txid or dns-random-srcport" <IP>

DNS - 反向 BF

dnsrecon -r 127.0.0.0/24 -n <IP_DNS>  #DNS reverse of all of the addresses
dnsrecon -r 127.0.1.0/24 -n <IP_DNS>  #DNS reverse of all of the addresses
dnsrecon -r <IP_DNS>/24 -n <IP_DNS>   #DNS reverse of all of the addresses
dnsrecon -d active.htb -a -n <IP_DNS> #Zone transfer

如果您能找到解析为内部IP地址的子域名,您应该尝试对该IP范围进行反向DNS暴力破解,向该域的NS发出请求。

DNS - 子域名BF

dnsenum --dnsserver <IP_DNS> --enum -p 0 -s 0 -o subdomains.txt -f subdomains-1000.txt <DOMAIN>
dnsrecon -D subdomains-1000.txt -d <DOMAIN> -n <IP_DNS>
dnscan -d <domain> -r -w subdomains-1000.txt #Bruteforce subdomains in recursive way, https://github.com/rbsec/dnscan

Active Directory 服务器

dig -t _gc._tcp.lab.domain.com
dig -t _ldap._tcp.lab.domain.com
dig -t _kerberos._tcp.lab.domain.com
dig -t _kpasswd._tcp.lab.domain.com

nslookup -type=srv _kerberos._tcp.<CLIENT_DOMAIN>
nslookup -type=srv _kerberos._tcp.domain.com

nmap --script dns-srv-enum --script-args "dns-srv-enum.domain='domain.com'"

DNSSec

DNSSec

#Query paypal subdomains to ns3.isc-sns.info
nmap -sSU -p53 --script dns-nsec-enum --script-args dns-nsec-enum.domains=paypal.com ns3.isc-sns.info

IPv6

使用“AAAA”请求进行暴力破解,以收集子域的IPv6地址。

dnsdict6 -s -t <domain>

使用 IPv6 地址进行反向 DNS 暴力破解

Reverse DNS 暴力破解是一种常见的渗透测试技术,用于查找与给定 IPv6 地址相关联的域名。

dnsrevenum6 pri.authdns.ripe.net 2001:67c:2e8::/48 #Will use the dns pri.authdns.ripe.net

DNS递归DDoS

如果启用了DNS递归,攻击者可以伪造UDP数据包中的源,以便使DNS将响应发送到受害者服务器。攻击者可以滥用ANY或DNSSEC记录类型,因为它们通常具有更大的响应。 检查DNS是否支持递归的方法是查询一个域名,并检查响应中是否包含标志"ra"(递归可用):

dig google.com A @<IP>

不可用:

发送到不存在账户的邮件

通过检查由发送到目标域中无效地址的电子邮件触发的非投递通知(NDN),通常会披露有价值的内部网络详细信息。

提供的非投递报告包括以下信息:

  • 生成服务器被识别为 server.example.com。

  • 返回了针对 user@example.com 的错误代码 #550 5.1.1 RESOLVER.ADR.RecipNotFound; not found 的失败通知。

  • 原始消息头中披露了内部IP地址和主机名。

The original message headers were modified for anonymity and now present randomized data:

Generating server: server.example.com

user@example.com
#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##
