/x04_checker

Primary LanguageSwift

X04 checks if an iOS application is running on a jailbroken device.. based on code by By Vineet Choudhary

with two improvements

  • making reverse engineering more difficult by
    • changed variable names
    • and obfuscated strings
  • suggesting having the scheme value encrypted in an xcconfig

usage

if UIDevice.current.x04 { }

==================

⚠️ note: the author asks for adding cydia to LSApplicationQueriesSchemes in info.plist

a much more secure way is having $(X0R_KEY) variable called from an xcconfig file, that have the string computed using concatenation

xcconfig concatenation

// X0R

X0R_KEY_A = sec

X0R_KEY_B = re

X0R_KEY_C = t

X0R_KEY = $(X0R_KEY_A)$(X0R_KEY_B)$(X0R_KEY_C)
