## Solution 3 – `frida-trace` (Frida ≥ 16)
|
||||
|
||||
Ikiwa hutaki kuandika mikono, unaweza kuruhusu **Frida** izalishe stubs za Java kwako na kisha uzihariri:
|
||||
```bash
|
||||
# Spawn the application and automatically trace the Java method we care about
|
||||
aadb shell "am force-stop owasp.mstg.uncrackable1"
|
||||
frida-trace -U -f owasp.mstg.uncrackable1 \
|
||||
-j 'sg.vantagepoint.a.a.a("[B","[B")[B' \
|
||||
-j 'sg.vantagepoint.a.c!*' \
|
||||
--output ./trace
|
||||
|
||||
# The first run will create ./trace/scripts/sg/vantagepoint/a/a/a__B_B_B.js
|
||||
# Edit that file and add the logic that prints the decrypted flag or
|
||||
# returns a constant for the root-checks, then:
|
||||
frida -U -f owasp.mstg.uncrackable1 -l ./trace/_loader.js --no-pause
|
||||
```
|
||||
Na Frida 16+ stub iliyoundwa tayari inatumia sintaksia ya kisasa ya **ES6** na itakusanywa na *QuickJS* runtime iliyo ndani – hauhitaji tena `frida-compile`.

## Suluhisho 4 – Mstari mmoja na Objection (2024)
|
||||
|
||||
Ikiwa una **Objection >1.12** iliyosakinishwa unaweza kutupa bendera kwa amri moja (Objection inazunguka Frida ndani):
|
||||
```bash
|
||||
objection -g owasp.mstg.uncrackable1 explore \
|
||||
--startup-command "android hooking watch class sg.vantagepoint.a.a method a \n && android hooking set return_value false sg.vantagepoint.a.c * \n && android hooking invoke sg.vantagepoint.a.a a '[B' '[B'"
|
||||
```
|
||||
* `watch class` inachapisha maandiko ya wazi yanayorejeshwa na utaratibu wa AES
|
||||
* `set return_value false` inalazimisha kila ukaguzi wa root / debugger kuripoti *false*
|
||||
* `invoke` inakuwezesha kuita njia moja kwa moja bila kubonyeza **Verify**.
|
||||
|
||||
> KUMBUKA: Kwenye Android 14 (API 34) lazima uendeshe Objection/Frida katika *spawn* mode (`-f`) kwa sababu *attach* imezuiwa na vizuizi vya **seccomp-bpf** vilivyoanzishwa mnamo Oktoba 2024.

## Maelezo ya kisasa ya Android (2023 - 2025)
|
||||
|
||||
* **libsu 5.x** na **Zygisk** huficha *su* vizuri; hata hivyo, ukaguzi wa msingi wa Java katika Kiwango cha 1 bado unashindwa ikiwa faili `/system/bin/su` ipo. Hakikisha unawasha **denylist** au tu ung'anishe `java.io.File.exists()` na Frida.
|
||||
* Frida 16.1 ilirekebisha ajali kwenye **Android 12/13** iliyosababishwa na *Scudo* allocator ya Google. Ikiwa unaona `Abort message: 'missing SHADOW_OFFSET'`, sasisha Frida (au tumia toleo la usiku la 17.0 lililotengenezwa mapema).
|
||||
* Kwa sababu Play Integrity ilichukua nafasi ya SafetyNet mnamo 2023, baadhi ya programu mpya zinaita API ya **com.google.android.gms.tasks.Task**. Kiwango cha 1 HAKIFANYI hivyo, lakini mkakati sawa wa ung'aniko ulioonyeshwa hapa unafanya kazi – ung'anisha `com.google.android.gms.safetynet.SafetyNetClient` na urudishe *EvaluationType* iliyotengenezwa.
