【asp木馬探測器】-在線掃描探測檢查asp站點木馬後門的程序
可以在線掃描檢查探測站點內的所有asp程序代碼，檢測代碼中是否含有危險代碼
目前檢測的特征碼有：CreateObject、Execute、Shell.Application、WScript.Shell、Eval、include......等。
對程序的改進是：增加擴展名後綴列表自定義、掃描文件大小限制、掃描超時限制、session驗證改復雜了一點點......
具體請自己打開原始代碼查看。
使用後，要麼及時刪除，要麼將登陸密碼改掉，盡量改復雜點。（雖然這個程序不會直接提供在線打開文件的功能，但仍然有可能被hacker利用）
准備下一個修改版本加入檢查iframe特征碼的功能，目前太多站點都是被人掛了iframe，當然，那只是表現，具體漏洞根源還是在程序或其他方面。
點擊這裡下載asp木馬探測器 [注意：解壓密碼和默認登陸密碼都是www.pifoo.com]
