Panopticon is a cross platform disassembler for reverse engineering. It disassembles AMD64, AVR and MOS-6502 binaries, groups code into functions and displays their bodies as control flow graphs. Panopticon allows reverse engineers to annotate functions and assembly listings with comments.
The current version supports 32 and 64 bit ELF files as well as raw memory dumps (AVR & MOS).
After successful installation launching Panopticon will start the Welcome Screen.
It displays previous sessions on the right, with the least recently opened first. Clicking one of them resumes the session, clicking the little trash can right to the sessions name deletes it.
The options on the left will ask the user to select a file and start a new session (top), start an empty session (middle) or open an executable shipped with Panopticon.
Clicking the top option presents the user with a file picker window.
The upper input field is the path to the directory that’s visible in the central
list. Typing a different path into it and pressing Enter
will navigate to the respective directory. Pressing the
will move the picker to the parent directory, if there is one. Clicking the
directories in the central list navigates into them. Clicking on files will
display a summary of the files contents below in case Panopticon recognizes the
file type. The entry field below the central list displays the selected file,
if any. Typing a file name into this entry is the same as selecting it in the
Double clicking a file or selecting a file with a single click and clicking the
Open button will load the file from disk and start a new session.
If the file is recognized as an executable and its instruction set is supported, Panopticon will start the disassembly process in background.
The workspace view displayed after selecting a file to work on lists all functions found in the executable. Clicking these selects them in the view. The workspace can be toggled between showing all functions in a graph and
In the latter, clinking on a single assembly code line will make a text cursor appear right to it. Typing will add the text as comment to the assembly line. The comment is saved by pressing Enter. To make multi-line comment use Shift+Enter.
Grabbing and holding the left mouse button while the cursor is not over a basic block moves the view.
When closing Panopticon or opening a new session via the
menu all changes made to the current session are saved without asking. The user
does not need to save anything explicitly. The
Save option in the
Project menu allows to set the file name and path to save to.
