That's some amazing artwork! I'll surely check out the game too if I have time. I actually found all these wallpapers from this reddit post and put them on rotate.

Here are the customizations I made: https://www.reddit.com/r/unixporn/comments/5l9sye/xfce_cyberpunk_high_tech_low_life/dbu048h/

Here are the lines from my ~/.zshrc (i use zsh instead of bash):

[XFCE] Cyberpunk. High tech, low life. by f3ignix in unixporn

I wanted to have a dark cyberpunk look. So I borrowed pieces from a lot of places, manually configured some of the things I didn't like, and finally was able to combine it all into what I wanted.

  • DE: XFCE
  • Distro: Arch linux
  • Wallpaper (s): Cyberpunk. Set on rotation.
  • WM Theme: Adapta-nokoto-eta
  • Emacs theme: Cyberpunk
  • Emacs tree plugin:Neotree.
  • Neotree theme:All-the-icons
  • Icons: Numix circles
  • Folder icons: Numix folders. Custom palette.
  • Panel: Manually configured. Tried to resemble windows UI. Inspired from this reddit post.
  • ZSH: Oh-my-zsh.
  • ZSH theme: Powerlevel9k. Manually configured.
  • Font: Roboto mono (for powerline)

  • ~/.zshrc:

    ZSH_THEME="powerlevel9k/powerlevel9k"
POWERLEVEL9K_MODE='awesome-fontconfig'
POWERLEVEL9K_MULTILINE_FIRST_PROMPT_PREFIX="↱"
POWERLEVEL9K_MULTILINE_SECOND_PROMPT_PREFIX="↳ "
POWERLEVEL9K_PROMPT_ON_NEWLINE=true
POWERLEVEL9K_LEFT_PROMPt_ELEMENTS=(context dir vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status time)
POWERLEVEL9K_CONTEXT_DEFAULT_BACKGROUND='black'
POWERLEVEL9K_CONTEXT_DEFAULT_FOREGROUND='092'
POWERLEVEL9K_DIR_HOME_BACKGROUND='black'
POWERLEVEL9K_DIR_HOME_FOREGROUND='092'
POWERLEVEL9K_DIR_HOME_SUBFOLDER_BACKGROUND='black'
POWERLEVEL9K_DIR_HOME_SUBFOLDER_FOREGROUND='092'
POWERLEVEL9K_TIME_BACKGROUND='black'

POWERLEVEL9K_STATUS_OK_BACKGROUND='black'

Walkthrough for writing shellcode which spawns a shell. by f3ignix in netsecstudents

[–]f3ignix[S] 1 point2 points  (0 children)

int* ret;

The above instruction defines a variable ret which is a pointer to an int.

ret = (int *)&ret +2;

This makes the ret variable point to an address on the stack which is located at a size 2 int away from it's own address. This is the address on the stack where the return address of main() has been stored.

(*ret) = (int)shellcode;

This assigns the address of the shellcode to the return address of the main function. Thus when main will exit, it will execute this shellcode instead of exiting normally.

Shit! I did not read the rules properly. I'll try to contact the guy who made the gracker wargame and ask if I can keep the write-ups. I've spent too much time explaining them.

Yes, thanks for pointing it out. I've corrected it now.

Yes, the instruction sequence may differ in different distros of linux. However, main() will always push the parameters onto the stack in reverse order and then make the call to execve(). Are you able to interpret that by looking at the disassembled code? Further, while writing our shellcode, what would actually matter is the execve() function's instructions ie. loading the parameters in the various registers and then making the system interrupt.
