I absolutely adore that reverse engineering part, instead of the bs “hacking done” in media, this is more believable from both hardware and software side.

Although I dont have that much knowledge in cybersecurity as an EE grad, but as someone that bored of cliche hacking explanations in shounen story, with green text and root access get bs lul, I give this a massive thumbs up.

After the boot up there’s still some unexplained hacking stuff like cliche mentioned above, but the prep part and dropping volt in the phone circuit board seems pretty cool.

From my understanding it’s like making the cpu execute its code like normal but not till it reach the timing where the line where it check for encryption, dropping the volt there make it skip that line of code, and returning the volt back so that the code run without noticing it skip that line and run like normal till return 0 command….. right?

I know Im stupid and wrong so someone with more impressive programming/engineering background could enlighten me but no wonder the guy said that the timing is extremely tight cause imagine interjecting a code while it’s running on a hardware level. Finding that small window frame is extremely impressive.

More simple explanation for those that watch frieren at the funeral, it’s like that time when fern explain frieren’s weakness of stoping mana detection when casting that only other elite mage can exploit cause of how tight the timing is.

hi
i am cybersecurity researcher
in my opinion the author describe some credit for doing the hacking better than typing fast on the keyboard to hack but it not that real because the worst thing to do is to make the phone lose power (remove the battery)
Phones these days encrypted by default and your password is the decryption key
phones do not check if your password is correct or not because that will mean it is very easy to bypass
in other words if do not have the correct password you get nothing

your best bet phone is that is phone is still on (no reboot/power off or battery removal)
looked phone are hackable with a 50% chance of success only if the battery is not removed or the user did not reboot the phone
fun fact secure phone has a feature if the user did not unlock the phone in x amount of time the phone will (auto reboot or power off)
if your phone is powered off or rebooted even the NSA/FBI can not unlock it

so not it is not realistic but it way better than the so-called hacking you see most of the time and the voltage thing is useless,
but the hacking here is just a plot device to raise the stakes
so i can understand why the author did it
