The Japanese government is going to run penetration tests against all the IoT devices in their country, in an effort to (1) figure out what’s insecure, and (2) help consumers secure them:
The survey is scheduled to kick off next month, when authorities plan to test the password security of over 200 million IoT devices, beginning with routers and web cameras. Devices in people’s homes and on enterprise networks will be tested alike.
The Japanese government’s decision to log into users’ IoT devices has sparked outrage in Japan. Many have argued that this is an unnecessary step, as the same results could be achieved by just sending a security alert to all users, as there’s no guarantee that the users found to be using default or easy-to-guess passwords would change their passwords after being notified in private.
However, the government’s plan has its technical merits. Many of today’s IoT and router botnets are being built by hackers who take over devices with default or easy-to-guess passwords.
Hackers can also build botnets with the help of exploits and vulnerabilities in router firmware, but the easiest way to assemble a botnet is by collecting the ones that users have failed to secure with custom passwords.
Securing these devices is often a pain, as some expose Telnet or SSH ports online without the users’ knowledge, and for which very few users know how to change passwords. Further, other devices also come with secret backdoor accounts that in some cases can’t be removed without a firmware update.
I am interested in the results of this survey. Japan isn’t very different from other industrialized nations in this regard, so their findings will be general. I am less optimistic about the country’s ability to secure all of this stuff — especially before the 2020 Summer Olympics.
