概要

ネットワークスキャンツールとして nmap が有名ですが、nmap でのネットワーク調査に時間がかかることもあり、zmapは、高速化のために、ステートレス化を行いました。

  • TCP/IPスタックを省略し、Ethernet フレームを直接生成します
  • コネクションステートをトラッキングしません
  • タイムアウトによる再送処理を行いません

ソースコードの取得

git clone git://github.com/zmap/zmap.git

インストール

ビルド

Kali Linux

Kali Linuxの環境でのビルド方法です。 

sudo apt-get install libgmp3-dev libpcap-dev gengetopt
sudo apt-get install cmake
sudo apt-get install byacc flex
cmake CMakeLists.txt

                                  e.g. 192.168.0.0/16
  -w, --whitelist-file=path     File of subnets to constrain scan to, in CIDR 
                                  notation, e.g. 192.168.0.0/16

  -T, --sender-threads=n        Threads used to send packets  (default=`1')
  -P, --probes=n                Number of probes to send to each IP  
                                  (default=`1')
  -d, --dryrun                  Don't actually send packets

Additional options:
  -C, --config=filename         Read a configuration file, which can specify 
                                  any of these options

     zmap -N 5 -B 10M -p 80 -o -  (find 5 HTTP servers, scanning at 10 Mb/s)
 
     zmap -p 80 10.0.0.0/8 192.168.0.0/16 -o (scan 10.0.0.0/8 and 
192.168.0.0/16 on port 80)
 
     zmap -p 80 192.168.1.2 192.168.1.3 (scan 192.168.1.2 and 192.168.1.3 on 
port 80)
 
selected probe-module (tcp_synscan) help
Probe module that sends a TCP SYN packet to a specific port. Possible
classifications are: synack and rst. A SYN-ACK packet is considered a success
and a reset packet is considered a failed response.
 
selected output-module (csv) help
no help text available

Oct 29 11:06:50.660 [WARN] blacklist: ZMap is currently using the default
blacklist located at /etc/zmap/blacklist.conf. By default, this blacklist
excludes locally scoped networks (e.g. 10.0.0.0/8, 127.0.0.1/8, and
192.168.0.0/16). If you are trying to scan local networks, you can change the
default blacklist by editing the default ZMap configuration at
/etc/zmap/zmap.conf.
