Iparmor 木馬克星 V5.40 Build 0414破解手記-演算法分析
作者：newlaos[CCG][DFCG]

軟體名稱：木馬克星5.40 Build 0414
下載地址：http://lpcsoft.yeah.net
大    小：341Kb
軟體說明：本軟體是動態監視網路與靜態特徵字掃描的完美結合，可以查殺3759種國際木馬，保證查殺：冰河所有版本，黑洞2001所有版本等等國產木馬，挑戰安全極限，殺盡天下木馬！木馬克星採用監視硬碟技術，不佔用cpu負荷，本軟體操作更智慧，佔用系統資源更少，查殺木馬更多!可以線上升級木馬庫，每天升級！

加密方式：註冊碼
功能限制：未註冊資訊提示+功能次數限制
PJ工具：TRW20001.23註冊版，W32Dasm8.93黃金版，FI2.5，eXeScope6.30
PJ日期：2003-04-23
作者newlaos申明：只是學習，請不用於商業用途或是將本文方法制作的序號產生器任意傳播，造成後果，本人一概不負。

說明：Build 0414與Build 0307的以機器碼求註冊碼的方式不同，它現改為由註冊名求註冊碼的方式，但用Build 0307的註冊資訊匯入登錄檔的話，依然可以成為註冊版

1、先用fi2.5發現此軟體沒有加殼

2、用w32dasm黃金版中文版對Iparmor.exe(也就是木馬克星5.40 Build 0414的主檔案)靜態態反彙編，再用“串式資料參考”，找到"註冊失敗"（多經典的句子呀），雙擊來到下面程式碼段：

3、再用TRW20001.23註冊版進行動態跟蹤，下斷BPX 0055CD74(通常在註冊成功與否的前面一些下斷，這樣，才能找到關鍵部分)，
先輸入註冊名：newlaos
假碼: 78787878
