![]() ![]() It is implemented to make sure that IP addresses do not conflict with each other on the same link. ![]() It is considered one of the core IPv6 network’s functions. This can be achieved through the Duplicate Address Detection (DAD) process. It aims to accommodate thousands of hundreds of unique devices on a similar link. We also discussed how to prevent this attack.Īn efficiently unlimited address space is provided by Internet Protocol version 6 (IPv6). We evaluated it and successfully found 12 zero-day vulnerabilities including smart lock, sharing car, smart watch, smart router, etc. In our research, we have implemented a prototype tool, called SACIntruder, to enable performing such brute-force attack test on IoT devices automatically. ![]() We found that an attacker can perform brute-force attack on this SMS authentication code automatically by overcoming several challenges, then he can steal the account to gain the control of IoT devices. Customer needs to register an account before using this app, phone numbers are usually suggested to be the account name, and most of these apps have a common feature, called Reset Your Password, that uses an SMS authentication code sent to customer phone to authenticate the customer when he forgot his password. The key idea is based on the observation that IoT device usually has an official application (app for short) used to control itself. We present in this paper an attack on Short Message Service (SMS for short) authentication code which aims at gaining the control of IoT devices without firmware analysis. Firmware vulnerability is an important target for IoT attacks, but it is challenging, because firmware may be publicly unavailable or encrypted with an unknown key. ![]()
