| 标题 | 可以修改脚本自身运行次数的vbs(Self modifying script) |
| 范文 | This script behaves like a virus This script shows you how a script can be self modifying, like viruses. It is a warning about the possibilities of macro viruses. File Name : selfmodify.vbs Requirement : none Author : Jean-Luc Antoine Submitted : 01/09/2001 Category : Other 代码如下: Const n = 1 Dim f, a, s, w w = WScript.ScriptFullName Set f = CreateObject("Scripting.FileSystemObject") Set a = f.OpenTextFile(w, 1) a.SkipLine s = chr(13) & Chr(10) & a.ReadAll a.Close Set a = f.CreateTextFile(w, True) a.Write "Const n = " & n + 1 & s a.Close WScript.echo "This script has been run " & n & " times" 原理就是每次运行脚本自身的代码就会被修改Const n = 1，这个1是一直变化的。 |
