    x = 10;

    printf("%i\n", x);

    return 0;
}

STEP 6: Save File As - 0x02_arm_32_hacking_int.c [:wq]

STEP 7: Build & Link

gcc -o 0x02_arm_32_hacking_int 0x02_arm_32_hacking_int.c

STEP 8: Run Binary

./0x02_arm_32_hacking_int
10

STEP 9: Run Radare2 - Debug Mode

r2 -d ./0x02_arm_32_hacking_int

STEP 10: Run Radare2 - Debug Step 1 [Examine Binary @ Entry Point]

aaa
s main
vv

STEP 11: Run Radare2 - Debug Step 2 [Examine int]

q
[0x0041b50c]> pf C @0x0041b512
0x0041b512 = 10

STEP 12: Run Radare2 - Debug Step 3 [Hack int]

[0x0041b50c]> wa mov r3, 0xd @0x00470512

STEP 13: Run Radare2 - Debug Step 4 [Review Hack]

[0x0041b50c]> pf C @0x0041b512
0x0041b512 = 13

STEP 14: Run Radare2 - Debug Step 5 [Hack Binary Permanently]

q
r2 -w ./0x02_arm_32_hacking_int
[0x000003fc]> aaa
[0x000003fc]> s main
[0x0000050c]> vv

[0x0000050c]> wa mov r3, 0xd @0x00000512
q
