Rebooted but exploit not removed. #3

Closed aloceres closed 11 months ago

aloceres commented 1 year ago

I am currently jailbroken and I want to disable hidden dock feature. When I reboot and rejailbreak it's still there.

This app only applies the tweaks as long as the device is on. As soon as you reboot (respring is fine), or power off the device, you must redo the tweaks you previously applied. This is the limitation of MacDirtyCow (the kernel vulnerability that is used), as this exploit stores everything in RAM to be executed. That part of RAM clears once device is rebooted

I already know how to remove it but when I go back into the jailbroken state, the exploit is still there even after reboot.

The app itself to the actual tweak you applied to it?

Super strange...hasn't happened to me but I'm also not jailbroken. What version of iOS are you on?

See https://www.reddit.com/r/jailbreak/comments/zxm9i7/tip_do_not_install_wdbfontoverwrite_via/ I guess this tweak has the same effect on jailbroken devices.

Ohhhh that may be it. Thanks!

However this is only a guess. Rootless jailbreaks shouldn't behave like that.

I didn't even think about that. That's true, rootless shouldn't do that. Must be a weird side-effect type thing ig. Super strange
