According to Scheel, the problem is that the HbbTV standard, carried by DVB-T signals and supported by all smart TVS, allows the sending of commands that tell smart TVs to access and load a website in the background.
Knowing this, Scheel developed two exploits he hosted on his own website, which when loaded in the TV’s built-in browser would execute malicious code, gain root access, and effectively take over the device.
While this incident represents one of the first of its kind, the bad news is this form of attack is only going to become more common as more and more everyday items get connected to the internet, providing hackers with greater numbers of potential zombie devices.”
The reason behind it is the issue of default credentials for wireless devices. This is going to bring billions of devices into the fold by 2020, which is only three years away. Whenever it is, there’s going to be so many of these things used by people with very limited understanding of what they are,” says Dine.
The network that IoT devices must use should be isolated and secured by a firewall. This isn’t that difficult to do.
The full story is admittedly lengthy, clocking in at over 8000 words, but worth the time to understand how botnet wranglers make money siccing their zombie device armies on unsuspecting targets. The sources that pointed Krebs to Anna Senpai’s identity were involved in using botnets on behalf of shadowy clients, unleashing them on security companies protecting lucrative Minecraft servers that host thousands of players. When their online gaming is obstructed — say, by repeated and annoying DDoS attacks — players leave, giving servers an incentive to jump ship to whichever security provider can ensure protection…in this case, providers that arranged for the botnet attacks in the first place.
With the SmartDevice capability, future Liebherr refrigerators will help in shopping and planning meals with intelligent food management. Stored groceries can be monitored using internal cameras and object recognition technology. This process not only captures images for viewing but also recognizes individual food items inside the refrigerator. This information flows automatically into an inventory list, which lets the customer see quickly and clearly what is in the refrigerator from anywhere. Using the SmartDeviceBox voice module, additional groceries can be added to a shopping list that customers can access when on the move using an app for iOS, Android or Windows devices.
During setup the app instructs the user to either plug in an Ethernet cable or press the ‘pair’ button on the camera which causes the camera to switch to host mode and offer up an open (aka insecure) wireless network. The app then scans for this network which is typically called CameraHD-(MAC address) and prompts the user to connect to it. This is an alarming feature for a camera designed for outdoor use particularly as the camera also offers a host of unfiltered network services, including the network video feed (RTSP), a bespoke internal messaging service for initiating alerts and two distinct web servers (nuvoton and busybox), one of which has an undocumented firmware upgrade page. Readers of our other blogs will know how much we like upgrading firmware…
Wi-Fi HaLow extends Wi-Fi into the 900 MHz band, enabling the low power connectivity necessary for applications including sensor and wearables. Wi-Fi HaLow’s range is nearly twice that of today’s Wi-Fi, and will not only be capable of transmitting signals further, but also providing a more robust connection in challenging environments where the ability to more easily penetrate walls or other barriers is an important consideration.
But, with more cities joining the Smart City revolution and investing in sensors and other IoT devices, the risk of a new tech bubble is rising. The same technology giants that helped Barcelona become a smart city are now pushing more pilots of newer technologies with little regard for solutions that already work and can be shared without incurring additional expenses.
Let’s consider a few of the most worrisome issues related to IoT today:
In the long run, we are being faced with a bunch of independent devices that can’t be managed by a single platform or protocol. Manufacturers are now being required to develop different versions for different standards, effectively increasing manufacturing and engineering costs, and reducing their market potential.
Many of the most serious flaws revealed a kind of sloppiness in the design and production of the devices, Brandon Creighton, Veracode’s research architect, told The Security Ledger. For example: both the Ubi and Wink Relay devices left debugging interfaces exposed and unsecured in their shipped product. That could provide an avenue for attackers who had access to the same network as the device to steal information or bypass other security controls.
Exposed debugging interfaces are useful during product testing, but have little or no utility to consumers. That suggests that the companies merely forgot to restrict access to them before shipping, Creighton said.
Anousheh is a serial entrepreneur and co-founder and chairman of Prodea Systems, a company that will unleash the power of the Internet to all consumers and dramatically alter and simplify consumer’s digital living experience. Prior to founding Prodea Systems, Anousheh served as co-founder, CEO and chairman of Telecom Technologies, Inc. The company successfully merged with Sonus Networks, Inc., in 2000.
This is an amazing story of accomplishment. It appears from her Prodea Systems website the company sells home automation and now Internet of Things which is a popular buzzword nowadays. This company made her enough money so she could buy a trip to ISS in 2006.
Scanning for Heatmiser thermostats on port 8068 really just requires a quick check for port 8068 being open – we can be fairly confident that anything with this port open is one of their devices. We can then make detailed check on port 80.
nmap -p 8068 -Pn -T 5 --open 78.12.1-254.1-254
nmap can easily do this scan. If you want to scan large blocks of addresses though, masscan is much faster.
You need to forward ports at your local router so if you try and access this thermostat from the Internet and you come in on (per above example) port 8068 that the router knows to forward all that traffic to whatever IP it has associated with that port. This allows users to access things inside their local network from anywhere on the Internet. It also allows anyone on the Internet to access that internal device.
Here is my opinion on this matter. As the world moves towards self driving cars and self driving planes, extremely complicated devices that you would think need human intervention, the world is also moving to take very simple devices, like household appliances and making them so they need human intervention. A thermostat should be set and forget. It should have simple intelligence to figure out what temperature to set a room. If a human must get involved in messing with a thermostat then perhaps something went wrong but it’s not an emergency like this:
A thermostat can certainly wait until you get home to physically figure out the problem and put it back on auto. The Internet of Things can certainly be useful for read only, like buzzing your phone when the dishes or laundry finishes. You can’t load laundry or dishes into these devices via the Internet so how do benefits from controlling them remotely, especially from remote Internet locations, outweigh the risks from allowing bad guys get into your local network.
Finally, here’s a link to a site that does port scanning on the Internet for you. Seems like a useful resource to know.
Plugging this into Shodan we get over 7000 results. That’s quite a lot. (note, you might need to register to use filters like this).
