搜索引擎蜘蛛劫持是seo黑帽中常用的一種手法,需要一定的技術(shù)支持getshell,然后上傳惡意的代碼到網(wǎng)站根目錄下面或者修改網(wǎng)站的一些文件，搜索引擎蜘蛛劫持的原理就是判斷來訪網(wǎng)站的是用戶還是蜘蛛,如果是蜘蛛就推送一個事先準備的惡意網(wǎng)站,如果是用戶就推送一個正常的網(wǎng)頁

1：蜘蛛判斷

判斷訪問的是用戶還是蜘蛛,如果是用戶就推送一個正常網(wǎng)頁,如果是蜘蛛就推送一個惡意網(wǎng)頁，判斷方式有兩種,一種是判斷蜘蛛的UA,一種是蜘蛛的ip段

2:蜘蛛劫持代碼

判斷如果是百度,360,搜狗,神馬蜘蛛就返回惡意的網(wǎng)頁給蜘蛛，如果不是就返回www.shangeedu.com網(wǎng)站的內(nèi)容,注意編碼是utf-8還是其它的

近期收到一些開發(fā)者反饋，為什么網(wǎng)站或智能小程序資源的內(nèi)容非常優(yōu)質(zhì)，但是沒有查詢到百度蜘蛛抓取記錄，或在百度搜索中沒有得到收錄和展現(xiàn)？在技術(shù)分析后發(fā)現(xiàn)，有些網(wǎng)站或智能小程序存在封禁百度蜘蛛的情況，導(dǎo)致百度蜘蛛無法正常抓取，所以無法在百度搜索中正常收錄和展現(xiàn)，或在搜索結(jié)果中的摘要展現(xiàn)為“存在robots封禁”字樣。為了讓廣大開發(fā)者的網(wǎng)站或小程序，在百度搜索中得到正常的收錄和展現(xiàn)，建議開發(fā)者及時根據(jù)以下

可能是因為網(wǎng)站存在未處理的URL鏈接或者被其他網(wǎng)站或者搜索引擎誤解導(dǎo)致的，也有可能是惡意的爬蟲在嘗試攻擊網(wǎng)站。為了解決這個問題，可以通過以下方式進行： 1. 對于不存在的頁面，應(yīng)該返回404錯誤頁面或者301重定向到一個已有的頁面； 2. 建立一個robots.txt文件來限制搜索引擎或者爬蟲的訪問； 3. 定期檢查日志文件來發(fā)現(xiàn)存在攻擊性的IP地址或者爬蟲； 4. 部署防火墻、權(quán)限管理和加密措
