Kaspersky finds security potholes in ‘smart’ roads

Published

on

Kaspersky Lab has proved that data gathered and processed by these road sensors can be dramatically compromised. This could potentially affect future city authority decisions on the development of road infrastructure.

In an attempt to explore security issues in smart city transport infrastructure and give recommendations on how to address them, a Kaspersky Lab Global Research & Analysis Team (GReAT) expert has conducted field research into the specific type of road sensors that gather information about city traffic flow. As a result, Kaspersky Lab has proved that data gathered and processed by these sensors can be dramatically compromised. This could potentially affect future city authority decisions on the development of road infrastructure.

Transport infrastructure in a modern megalopolis represents a very complicated system, containing different sorts of traffic and road sensors, cameras, and even smart traffic light systems. All the information gathered by these devices is delivered and analysed in real-time by the special city authorities. Decisions about future road constructions and transport infrastructure planning can be made based on this information. If the data is compromised it can cause millions in losses to the city.

In particular, if fraudulent access to the transport infrastructure is gained, the following may occur:

·         The data gathered by road sensors may be compromised in an attempt to sabotage it or resell it to third parties;

·         Modification, falsification and even deletion of critical data;

·         Demolition of the expensive equipment;

·         Sabotage the work of the city authority’s services.

Recent research by a Kaspersky Lab expert in Moscow was conducted on a network of road sensors that gather traffic flow information – in particular the quantity of vehicles on the road, their type and average speed. This information is transferred to the city authority’s command center. City traffic authorities receive the information and use it to support and update a real-time road traffic map. The map, in turn, could then serve as a source of data for city road system construction or even for automating traffic light system controls.

The first security issue, discovered by the researcher, was the name of the vendor clearly printed on the sensor’s box. This crucial information helped the Kaspersky Lab expert to find more information online about how the device operates, what software it uses etc. The researcher discovered that the software used to interact with the sensor, as well as technical documentation, were all available on the vendor’s website. In fact, the technical documentation explained very clearly what commands could be sent to the device by a third party.

Just walking near the device, the researcher was able to access it via Bluetooth as no reliable authentication process was implemented. Anyone with a Bluetooth-enabled device and software for discovering passwords via multiple variants (brute force) could connect to a road sensor in this way. But what to do next?

Using the software and technical documentation, the researcher was able to observe all data gathered by the device. He was able to modify the way the device gathers new data: for example changing the type of vehicle recorded from a car to a truck, or changing the average traffic speed.  As a result all newly gathered data was false and not applicable to the needs of the city.

“Without the data gathered by these sensors, actual traffic analysis and subsequent city transport system adjustments would not be possible. These sensors can be used in the future to create a smart traffic light system and also to decide what kind of roads should be built, and how traffic should be organised, or reorganised, in what areas of the city. All these issues mean that the work of sensors and the quality of data gathered by them should be accurate and stable. Our research has shown that it is easy to compromise the data. It is essential to address these threats now, because in the future this could affect a bigger part of the city’s infrastructure”, said Denis Legezo, Security Researcher, Global Research and Analysis Team (GReAT), Kaspersky Lab.

Kaspersky Lab recommends several measures to help prevent a successful cyberattack against transport infrastructure devices. These include:

·         Remove or hide the vendor’s name on the device, as this could help an attacker to find tools online for hacking the device;

·         Change the default names of the device and disguise the vendor’s MAC addresses if possible;

·         Use two steps of authentication on devices with Bluetooth connectivity and protect them with strong passwords;

·         Cooperate with security researchers to find and patch vulnerabilities.

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entries via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.

Scientist suggest that the use of emojis will help us gain the same satisfaction from digital interactions as we enjoy from personal contact.

Almost two decades later, and we have over 2600 unique emojis to perfectly express what we feel, thank you Mr Kurita! Join HMD, the home of Nokia phones as we celebrate World Emoji Day on the 17th of July with these interesting emoji facts:

The most popular emoji used is “Person Shrugging”

1.       The Nokia 3310 was chosen as one of the first 3 “National” emojis for Finland… it represents unbreakable!

2.       South Africa’s favourite emoji is the “Kiss and wink”… how sweet SA!

3.       French is the only language where a ‘smiley’ does not top the list for its use

4.       On average, over 60 billion emojis are sent on Facebook every day

5.       For the first time ever, the Oxford Dictionaries Word of the Year was a pictograph! The “Face with Tears of Joy” was crowned word of the year in 2015

6.       According to Emojipedia, some of the most requested emoji’s include afro, a bagel and hands making a heart

7.       To include all races, a diversity pack was released in 2017
