    xAnalyzer plugin for x64dbg
    by ThunderCls - 2016 (From CrackLatinos Team)

    xAnalyzer is a plugin for the x86/x64 x64dbg debugger by @mrexodia. This plugin is based on the code by @mrfearless APIInfo-Plugin-x86 (https://github.com/mrfearless/APIInfo-Plugin-x86) although some improvements and additions have been made. xAnalyzer is capable of calling internal commands of x64dbg to make all kind of analysis and also integrates one of his own. This plugin is going to make an extensive function calls analysis to add complementary information, something close at what you get with OllyDbg.
    Some of the functions and improvements are:
    Extended WINAPI calls analysis with arguments added
    • Analysis of indirect calls
    • Analysis of nested calls
    Once the debugged application is loaded and reaches the Entrypoint, xAnalyzer is going to launch a mix of different analysis over the static code to make it even more comprehensible to the user just before starting the debuggin task.

    • Copy xAnalyzer.dp32 and/or xAnalyzer.dp64 files and apis_def folder to x32/x64 plugins directory of x64dbg
    • Look under the "Plugins" menu in the main x64dbg window or in the secondary menu in the Disasm window as well
    Features & Usage:
    • The plugin launches automatically, no config, no nothing.
    • If by any means you need to re-analyze the code, you can make right clic on the disassembler window and choose the option at the end "xAnalyzer"/"Extended analysis"

    New release, Some additions and improvements has been made to this version:
    • [+] Generic arguments for undefined functions and internal subs
    • [+] Smart function comments and arguments (only functions with arguments on stack are being processed). This allows xAnalyzer to give a cleaner sight of the code by just processing and commenting those functions with actual arguments.
    • [+] Detection of indirect function calls with scheme CALL -> DYNAMIC_MEMORY -> API
    • [+] Detection of indirect function calls with scheme CALL -> REGISTER/REGISTER + DISPLACEMENT -> API
    • [+] Detection of indirect function calls with scheme CALL -> JMP -> JMP -> API
    • [+] Automatic loops detection
    • [+] Fixed minors bugs.
    • [+] Code rearrangements.

    So strange :)
    I think, you can try uncheck "System BreakPoint", only choose "Entry BreakPoint" (Options >Preferences")

    Thanks for the tip,
    it would be much better if the 'About' shows the version number so we can track changes. just an opinion ;)

    Changes in Update 2.4.1:
    • Added a new hotkeys scheme
    • Added new options to control which previous analysis data should be erased. (This gives the user more control on what to keep and what to delete and also the possibility to work seamlessly with map loader plugins like SwissArmyKnife, etc).
    • Added new commands (old ones have been deprecated)
      xanal selection : Performs a selection analysis
      xanal function : Performs a function analysis
      xanal exe : Performs an entire executable analysis
      xanalremove selection : Removes a previous selection analysis
      xanalremove function : Removes a previous function analysis
      xanalremove exe : Removes a previous entire executable analysis
      xanal help : Brings up to the log window some help text
    • Fixed automatic analysis not launching on startup
    • Fixed various api definition files. It´s recommended to download this apis_def.zip down below file and overwrite the files with the ones already downloaded or just copy the whole new fresh folder and delete the older one.
    Changes in update 2.4.2:
    • Fixed BoF when argument flags comment overpassed MAX_COMMENT_SIZE
    • Fixed function name search bug when definition lies in a second .api file

    New release :
    xAnalyzer 2.5.0
    -Removed [EBP+/-] instructions as possible function caller arguments
    -Removed prefix "0x" of all function arguments values since hexadecimal is inferred
    -Fixed arguments where pointer variables wouldn't show correctly as pointers but as base data type instead
    -Added recognition of stack pointer usage (ESP) as possible argument for function calls (x86)
    -Added use of accurate data type name in arguments instead of generic/base data type name
    -Added function smart tracking feature (Smart prediction and recognition of indirect function calls like: CALL {REGISTER}, CALL {POINTER})
    -Added name of function pointers as parameters (the entire function name, if detected, will be used instead of just the address)​
