Description
Adversaries may abuse various implementations of JavaScript for execution. JavaScript is a platform-independent scripting language (compiled just-in-time at runtime) commonly associated with scripts in webpages, though JavaScript can be executed in runtime environments outside the browser.
JScript is the Microsoft implementation of the same scripting standard. JScript is interpreted via the Windows Script engine and thus integrated with many components of Windows such as the Component Object Model and Internet Explorer HTML Application (HTA) pages.
Adversaries may abuse various implementations of JavaScript to execute various behaviors. Common uses include hosting malicious scripts on websites as part of a Drive-by Compromise or downloading and executing these script files as secondary payloads. Since these payloads are text-based, it is also very common for adversaries to obfuscate their content as part of Obfuscated Files or Information.
Within industrial control system networks, adversaries most commonly abuse the use of JavaScript on overlap assets that run on operating system platforms similar to Enterprise devices.
