Creating a Basic Dropper in Jscript
The primary client scripting language for web browsers is JavaScript,
which is an interpreted language that is processed inside the browser.
Jscript is a dialect of JavaScript
developed and owned by Microsoft that is used in Internet Explorer.
It can also be executed outside the browser through the Windows Script Host,
which can execute scripts in a variety of languages.
When executed outside of a web browser, Jscript is not subject
to any of the security restrictions enforced by a browser sandbox.
This means we can use it as a client-side code execution vector
without exploiting any vulnerabilities.
