IDA is not a binary file editor. Keep that fact in mind anytime you think about patching a binary with IDA. However, it is a particularly good tool for helping you enter and visualize potential changes. By familiarizing yourself with IDA’s full range of features and combining the information that IDA can generate with appropriate scripts or external programs, binary patching easily becomes possible.

In the coming chapters, we will cover the many ways in which IDA’s capabilities can be extended. For anyone interested in making the most out of IDA’s capabilities, basic scripting skills and an understanding of IDA’s plug-in architecture are essential, as they offer you the capability to add behaviors wherever you feel IDA is lacking.
