php網站被掛木馬修復方法總結,php掛木馬總結


在linux中我們可以使用命令來搜查木馬文件,到代碼安裝目錄執行下面命令

代碼如下 復制代碼
find ./ -iname "*.php" | xargs grep -H -n "eval(base64_decode"

搜出來接近100條結果,這個結果列表很重要,木馬都在裡面,要一個一個文件打開驗證是否是木馬,如果是,馬上刪除掉

最後找到10個木馬文件,存放在各種目錄,都是php webshell,功能很齊全,用base64編碼

如果你在windows中查找目錄直接使用windows文件搜索就可以了,可以搜索eval或最近修改文件,然後如果是dedecms我們要查看最新dedecms漏洞呀然後修補。


下面給個php木馬查找工具,直接放到你站點根目錄

代碼如下 復制代碼

今天我的網站被掛木馬了

是卡巴斯基的誤報,已經解訣了,我也是一樣,進入安全模式搞了很久都沒有搞定,後來手動更新卡巴斯基的病毒庫後就好了。
下面是有關此事的通知:
5月19日 下午 15點20分,CNZZ方面收到卡巴斯基中國公司最新更新病毒庫通知,對方已經解決了對CNZZ統計的誤報問題,CNZZ統計服務目前已在第一時間恢復正常。如果部分用戶仍然報毒,請手動更新卡巴斯基病毒庫。
 

網站被掛了木馬,只要是indexphp就開不了

一般情況下,電腦中毒或者中木馬或者病毒之後,木馬病毒都會破壞系統的,一般殺毒軟件是不能解決這些問題的,推薦你使用金山網盾或者金山急救箱等系統修復工具對系統進行修復,我就是這樣解決問題的。
建議你最佳解決方案

第一步:下載金山毒霸2011【百度搜索 金山毒霸】 選擇官方下載

第二步 安裝完以後,打開金山毒霸,點擊“全盤查殺”
