黑客工具介绍之DDoS攻击工具Trinoo分析

本使用了Berkeley的"rcp"ming令。只要监视本系统到网络外部IP地址的"rcp"连接(514/TCP),就能够迅速地得到确定。(注:脚本中使用的"rcp"需要主机间的信任关系,这往往是在用户的~/.rhosts文件中包含"+ +"。通过检查这个文件也能立刻知道是否可能出现了系统入侵。)

  (对trinoo更进一步的分析请参阅附录E中由George Weaver of Pennsylvania State University 和 David Brumley of Stanford niversity编写的"更多的监测trinoo方法"一文。)
  附录A:"ngrep"捕获的网络会话

  以下是"ngrep"捕获的一个攻击会话实例:

  # ngrep -x ".*" tcp port 27665 or udp port 31335 or udp port 27444
  interface: eth0 (192.168.0.200/255.255.255.0)
  filter: ip and ( tcp port 27665 or udp port 31335 or udp port 27444 )
  match: .*

  附录B - Trinot脚本

  # trinot v. 1.1
  # By Dave Dittrich
  #
  # Send commands to trinoo daemon(s), causing them to PONG, *HELLO*
  # to all their masters, exit, etc. Using this program (and knowledge
  # of the proper daemon password), you can affect trinoo daemons
  # externally and monitor packets to verify if the daemons are up,
  # expose their masters, or shut them down.
  #
  # Needs Net::RawIP (http://quake.skif.net/RawIP)
  # Requires libpcap (ftp://ftp.ee.lbl.gov/libpcap.tar.Z)
  #
  # Example: ./trinot host1 [host2 [...]]
  # ./trinot -S host
  # ./trinot -p password -P host
  #
  # (This code was hacked from the "macof" program, written by
  # Ian Vitek )
  require 'getopts.pl';
  use Net::RawIP;
  {}});
  chop($hostname = `hostname`);
  Getopts('PSDp:f:s:d:l:i:vh');
  die "usage: $0 [options] host1 [host2 [...]]\t-P\t\t\tSend \"png\" command\t-S\t\t\tSend \"shi\" command\t-D\t\t\tSend \"d1e\" command (default)\t-p password\t\t(default:\"l44adsl\")
