In computer science, mobile code is software transferred between systems, e.g. transferred across a network or via a USB flash drive,
and executed on a local system without explicit installation or
execution by the recipient. Examples of mobile code include scripts (JavaScript, VBScript), Java applets, ActiveX controls, Flash animations, Shockwave movies (and Xtras), and macros embedded within Microsoft Office documents.
Mobile code can also download and execute in the client workstation
via email. Mobile code may download via an email attachment (e.g.,
macro in a Word file) or via an HTML email body (e.g., JavaScript). For
example, the ILOVEYOU,
TRUELOVE, and AnnaK email viruses/worms all were implemented as mobile
code (VBScript in a .vbs email attachment that executed in Windows
Scripting Host).
In almost all situations, the user is not aware that mobile code is downloading and executing in their workstation.
Mobile code technologies can be used to support three different paradigms:
Mobile code can also be encapsulated or embedded in other file
formats not traditionally associated with executable code. An example
of this form of encapsulation is the presence of JavaScript in a PDF.[1]
Mobile code also refers to code "used for rent", a way of making
software packages more affordable. i.e. to use on demand. This is
specially relevant to the mobile devices being developed which are
cellular phones, PDAs, etc all in one. Instead of installing software
packages, they can be "leased" and paid for on a per-usage basis.
