It is said that the massive DDoS attack that took place on October 21st, which brought down a large part of the internet for several hours, twice, came from IoT devices.
Do you have any in your home? Have they been hacked? You could find that the next time the internet is under attack, your devices are part of the cause.
IoT devices are basically smart devices that are connected to the internet, such as your heating, lighting, audio system, TV, electric toaster and coffee machine. Anything that is connected to your Wi-Fi and then to the internet is an IoT device.
They can be controlled remotely by web apps and phone apps, and they are great for automating the home. However, they are open to hackers and they can be abused.
If hackers gain access to thousands of devices they can then use them to launch DDos (distributed denial of service) attacks. Basically so many devices try to access a website or web service that it cannot cope and dies under the strain.
BullGuard has come to the rescue with a tool that finds out whether the details of your internet-connected devices are available online. If they are, then a hacker could get them and then hack into them.
“The Internet of Things has moved rapidly from an early adopter market into the mainstream, but in doing so has introduced a range of new security concerns for consumers,” said Paul Lipman, CEO, BullGuard.“ We’ve made an important first step towards addressing these issues with IoT Scanner, a tool that allows anyone to check if smart devices in their home are secure.”
Check your devices
Go to the Internet of Things Scanner and click the button Check if I am on Shodan. This is a search engine for IoT devices and it could be used by hackers.
If the results are negative and you aren’t on Shodan, there is a deep scan available. There is a possibility that deep scanning might cause Shodan to index your devices. If you have IoT devices and you’re not on Shodan, you might be after a deep scan.
However, a deep scan is the only way to see if you are really on there. I went ahead anyway.
I am OK, but are you? Have you tried this tool? Go to iotscanner.bullguard.com and try it. Let us know how you got on in the comments below.
