Read MoreAlthough IDA is mostly intended to be used for static analysis, i.e. simply looking at unaltered binaries, there are times you do need to make some changes. For example, you can use it to fix up some obfuscated instructions to clean up the code flow or decompiler output, or change some constants used in the […]

Read MoreList views (also called choosers or table views) are used in many places in IDA to show lists of different kind of information. For example, the Function list we’ve covered previously is an example of a list view. Many windows opened via the View > Open subviews menu are list views: Exports Imports Names Strings Segments Segment registers Selectors Signatures Type libraries Local types Problems Patched […]
Read MoreName mangling (also called name decoration) is a technique used by compilers to implement some of the features required by the language. For example, in C++ it is used to distinguish functions with the same name but different arguments (function overloading), as well as to support namespaces, templates, and other purposes. Mangled names often end up in the […]
Read MoreA rather nasty issue evaded our testing and found its way into IDA 7.6: using the PyQt5 modules that are shipped with IDA, QTreeView (or QTreeWidget) instances will always fail to display contents. E.g., the following script from PyQt5 import QtWidgets tree = QtWidgets.QTreeWidget() item = QtWidgets.QTreeWidgetItem() item.setText(0, “Test col#0”) tree.addTopLevelItem(item) tree.show() used to render like so: but now looks like this: The fix In order to solve this, […]
Read MoreIn IDA’s disassembly, you may have often observed names that may look strange and cryptic on first sight: sub_73906D75, loc_40721B, off_40A27C and more. In IDA’s terminology, they’re called dummy names. They are used when a name is required by the assembly syntax but there is nothing suitable available, for example the input file has no […]
Read MoreThe user directory is a location where IDA stores some of the global settings and which can be used for some additional customization. Default location On Windows: %APPDATA%/Hex-Rays/IDA Pro On Linux and Mac: $HOME/.idapro For brevity, we’ll refer to this path as $IDAUSRin the following text. Contents/settings The directory is used to store the processor module caches (proccache.lst and proccache64.lst) as well […]
