Ghidra versions. You might consider comparing a fresh import of any program you will continue to reverse engineer to see if the latest Ghidra provides better results.

Debugger

+

Memory Search

-

ATTENTION: Please delete and re-import the default Debugger tool!

- -

We are introducing a new debugger connection system called Trace RMI. This is replacing the older system, - which we are calling the Recorder system.

- -

The most noticeable difference will be a new menu for launching targets. It is very similar to the previous system, but with some key differences:

-
- -
- -

The next most noticeable difference will be the replacement of the Interpreter window with the Terminal window. This is a proper VT-100 - terminal emulator, so the experience will be much like, if not identical to, how you'd debug in a plain terminal, except embedded into and integrated with Ghidra. - Some notable improvements that brings:

-
- -
- -

You may also notice the replacement of the Debugger Targets window with the Connection Manager window, and the replacement - of the Objects window with the Model window. These are operationally very similar to their previous counterparts.

- -

For Power Users: The launchers are just shell scripts on Linux and macOS, and batch files on Windows. We have provided plugins - for integrating with GDB, LLDB, and the Windows Debugger. So long as your target works with one of these debuggers, orchestrating - another kind of target is mostly a matter of creating a new shell script. This is usually accomplished by using the most similar - one as a template and then trying it out in Ghidra. When errors occur, Ghidra will inform you of what progress it made before it - failed, and the Terminal should display any error messages produced by your script.

- -

For Developers: Developers may notice that debugger integration is now all done using Python 3. - We have specified a new protocol we call Trace RMI, which provides client access to Ghidra's trace databases over TCP. - It uses protobuf and is substantially simpler than the previous GADP protocol. We have provided the client implementation in - Python 3. Existing integrations can be fairly easily extended, if necessary. For example, see the support for Wine we included in our GDB plugin.

- -

If you wish to integrate a completely new debugger, and it has a Python 3 API, then things are relatively straightforward, so long as - the debugger provides the events and information that Ghidra expects. Use an existing plugin as a template or reference and have fun. - If the new debugger does not have Python 3 bindings, the protobuf specification is available, so the client can be ported, if necessary.

- -

IMPORTANT: To use the new Trace RMI system, you will need Python3 (3.7 to 3.12 supported) installed on your system. - Additional setup may be required for each type of debug connection. Press F1 in the debug connector's launch dialog - for more information.

- -

Overall, we believe this a substantially more approachable system than our previous DebuggerObjectModel SPI used in the Recorder system.

+

The Search Memory feature in Ghidra has been updated substantially to provide two new features:

+
+ +
+ +

Set operations, accessible from the pull-down menu under Search, allow you to augment + results by performing boolean operations on an existing search. For example, you might search for the hex pattern "DE AD" using Search, + add "BE EF" to the pattern field, and then select "A-B" to retrieve a list of byte sequences that begin with "DE AD" but do not include "DE AD BE EF". + Scanning for changes is most useful in a dynamic environment, such as the Debugger. Given an existing search, you can look for values that have changed, + increased, decreased, or remained the same. Simple examples might include looking for counters while a process is running, checking for areas of decompressed + memory, or identifying active areas of the heap.

+ +

PDB

+

The PDB Symbol Server Search Config dialog has been changed, allowing the user to mark symbol servers as trusted or untrusted. + This is an improvement over the previous mechanism that based trust on the symbol server's connection type.

-

GhidraGo

+

Debugger

-

GhidraGo is an experimental feature that adds integration support for Ghidra URL's and Ghidra Tools. GhidraGO can now process GhidraURL's that - locate folders within a project instead of only programs. For example a remote GhidraURL locating a project folder will open a read only view of - the repository in the front end tool and select the folder from the URL. If the GhidraURL refers to a folder in the currently open - active project, then the folder is selected within the active project's view instead of a read only view. -

+

ATTENTION: Please either delete and re-import the default Emulator tool, or + manually remove the TraceRmiPlugin from your EmulatorTool!

+ +

There are new launchers/features for the traceRMI version of dbgeng, including extended launch options, kernel debugging, and + remote process server connections.

-

PDB

-

The PDB data type processing changes from release 11.0 have been further enhanced, simplifying the processing model and reducing the number of datatype - conflicts. The algorithm for choosing the primary symbol at an address has been improved to provide the richest possible information. The PDB Universal - Analyzer has been split into multiple analyzers so that PDB function processing can follow interim analyzers that specialize in finding code. - Lastly, the Load PDB Task has been improved to schedule appropriate follow-on analyzers that are selected in the Analysis Options.

+

Decompiler

-

Version Tracking

+

The Decompiler can now automatically recover strings built on the stack and initial support for optimized heap strings has been added. + Stack strings are typically found in optimized code and obfuscated malware.

-

Version Tracking Session files may now be added to a shared project repository. Once a version tracking file has been checked in to a project, - it must be checked out for exclusive access. For more information, see help found in the Version Tracking's - Session Wizard help for more information.

+

A new Search All action has been added which displays a table containing the results found within the current function.

-

NOTE: Prior to adding a pre-existing VT Session to a shared project repository, it is highly recommended that it first be re-opened - and saved. This will upgrade the VT Session internal version to prevent its use with older versions of Ghidra which will not respect - the exclusive checkout requirement.

- -

Mach-O Improvements

-

Mach-O support continues to improve, adding support for new features as well as filling in some gaps that existed for several years. - The latest dyld_shared_cache files use a new format for pointer fixups, which Ghidra now supports. A new GFileSystem has also been - implemented to import and/or extract individual Mach-O binaries from Mach-O "file sets" (i.e., kernelcache). A second new GFileSystem - has been added which can extract Apple LZFSE-compressed files. Other improvements have also been made to provide more complete markup of Mach-O load commands.

- -

Swift

-

Initial support for binaries written in the Swift Programming Language has been added. The new support relies on the native Swift demangler being - present on the user's system. Swift is automatically bundled with XCode on macOS, and can be optionally installed on Windows and Linux. - See the "Demangler Swift" analyzer options for more information. Type information gathered from the demangled Swift symbol names is used to - create corresponding Ghidra data types. This currently works for Swift primitives and structures, but more work needs to be done to include - classes and other advanced data types. Swift-specific calling conventions are also applied to demangled Swift functions.

+

Programming Languages

-

Usability

+

Golang support for versions 1.15 and 1.16 have been added. This brings the supported Golang versions to 1.15 thru 1.22.

+ +

Processors

+ +

There have been quite a few improvements to the Sparc processor specification, including additional instructions, 64-bit relocation support, and better + handling of call/return detection through tracking of the o7 link register. In addition, the calling convention for both sparc 32 and 64 bit binaries + have had an overhaul to support hidden structure return and much improved parameter allocation of floating point and general data types.

-

There have been many improvements to keyboard only actions and navigation in Ghidra. These changes will be welcome for those who - prefer to use the keyboard as much as possible and those needing better accessibility. Improvements include:

-
- -
- -

Other Improvements

- -

Support for the SquashFS filesystem has been added.

- -

A new wildcard assembler API has been added that can generate all possible variants of an instruction with a variety of wildcards for operands. - Two new scripts, FindInstructionWithWildcard and WildSleighAssemblerInfo, demonstrate how to use the API. - For more information, see help and search for Wildcard Assembler. - -

A new Runtime Information dialog has replaced the Show VM Memory dialog. The dialog contains more information - which can aid in debugging, including version information, classpath, defined properties, environment variables, and more.

- -

The GhidraDev Eclipse plugin has a new wizard for importing an existing Ghidra module source directory. This will work best with Ghidra module projects - created against Ghidra 11.1 or later.

+

The Intel M16C/60/80 sleigh processor specifications have been added. In addition, there have been numerous fixes to the + ARM, RX, M68000, PIC16, PPC, and x86 processor specifications.

+ +

Other Improvements

-

Finding references to fields within a structure has been greatly improved. Previously many references to the field would be missed if they occurred within - functions calling external functions using the structure, or when the field was used only in local variables dynamically generated by - the decompiler.

+

Actions have been added to compare functions directly from the Listing, Decompiler, or Functions Table via popup menu items. If there + is already a Function Comparison window showing, there are two actions: one to add the selected function(s) to the existing comparison, and + one to create a new Function Comparison Window. This allows a workflow where users can build up a set of functions to compare as they browse + around instead of having to select them all at once.

-

Golang versions 17 thru 22 are now supported.

+

For Ghidra script and plugin developers who would prefer to use Visual Studio Code, a new script VSCodeProjectScript will create a new + Visual Studio Code project that is setup to do Ghidra scripting and module development. The capabilities are similar to the Eclipse + GhidraDev plugin.

-

DWARF5 debug format is now supported. In addition, DWARF line number information processing has been incorporated into the base DWARF analyzer and the - separate DWARF line number analyzer has been removed.

- +

There have been major speed improvements when creating or modifying large structures within the structure editor. In general large structure manipulation + should perform fluidly no matter the size of the structure. If the structure contains a large number of defined data, there could still be some degradation in + speed. Some fixed performance issues include: resizing a structure smaller or larger, clicking on an item to select a row, and defining a data type either with keyboard actions or dragging + and dropping from the data type manager. In addition, the behavior of automatically growing the size of a structure has been made consistent. Defining data on the last element of a structure + is allowed to automatically grow the structure to fit the data type. Defining data anywhere other than the last element isn't allowed if the data type does not fit because + of defined data that would need to be cleared, or there are not enough undefined bytes.
