DO YOU EVEN REVERSE ENGINEERING, BRO?!? • The crypto is described in the JNI function ‘Java_org_appcelerator_titanium_TiVerify_filterD ataInRange’ in ‘libtiverify.so’ byte[] filterDataInRange(byte[] bytes, int offset, int count) { SecretKeySpec key = new SecretKeySpec(bytes, bytes.length -‐ 0x10, 0x10, "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.DECRYPT_MODE, key); return cipher.doFinal(bytes, offset, count); }
