Apk Time Graveyard Pin Patched -

Thus the for a live instance depends on the server time when the APK was run.

pin ^ time = 0xCA7 (within low 16 bits) => pin = time ^ 0xCA7 But pin must be 6 digits (100000 to 999999) and digits sum to 24. Suppose current time = 14:45 → timeInt = 1445 . apk time graveyard pin

In that case: pin = 1337 ^ 0xCA7 = 1337 ^ 3243 = 0x0539 ^ 0x0CA7 = 0x099E = 2462 → PIN 002462 , sum=14 (still fails sum). So sum check must be ignored. Thus the for a live instance depends on

bool verifyPin(JNIEnv *env, jobject thiz, jstring pin, jint timeInt) { const char *pinStr = (*env)->GetStringUTFChars(env, pin, NULL); int pinInt = atoi(pinStr); int computed = (pinInt ^ timeInt) & 0xFFFF; // Note: only low 16 bits // Graveyard magic constant int expected = 0xCA7; In that case: pin = 1337 ^ 0xCA7
