Smartphones can be compromised when charged using a standard USB connection connected to a computer, Kaspersky Lab experts have discovered in a proof-of-concept experiment.
Have you ever wondered how safe your smartphone and data are when you connect the device to freely available charging points at airports, cafes, parks and public transport? Do you know what, and how much data your mobile device is exchanging with these points while it’s charging? Kaspersky Lab researchers became curious and conducted research to find the answers to these questions.
As part of this research, the company’s experts tested a number of smartphones running various versions of Android and iOS operating systems in order to understand what data the device transfers externally while connected to a PC or Mac for charging. The test results indicate that the mobiles reveal a whole litany of data to the computer during the ‘handshake’ (a process of introduction between the device and the PC/Mac it is connected to), including: the device name, device manufacturer, device type, serial number, firmware information, operating system information, file system/file list, electronic chip ID. The amount of data sent during the handshake varies depending on the device and the host, but each smartphone transfers the same basic set of information, like device name, manufacturer, serial number etc.
Now that smartphones almost always accompany their owner, the device serves as a unique identifier for any third party who might be interested in collecting such data for some subsequent use. But it wouldn’t be a problem if collecting a few unique identifiers was all that an attacker could do with a device connected to an unknown computer or charging device.
Back in 2014, a concept was presented at Black Hat that a mobile phone could be infected with malware simply by plugging it into a fake charging station. Now, two years after the original announcement, Kaspersky Lab experts have been able to successfully reproduce the result. Using just a regular PC and a standard micro USB cable, armed with a set of special commands (so-called AT-commands), they were able to re-flash a smartphone and silently install a root application on it. This amounts to a total compromise of the smartphone, even though no malware was used.
Although information about actual incidents involving fake charging stations has not been published, the theft of data from mobiles connected to a computer has been observed in the past. For example, this technique was used in 2013 as part of the cyberespionage campaign Red October. And the Hacking Team group also made use of a computer connection to load a mobile device with malware. Both of these threat actors found a way to exploit the supposedly safe initial data exchange between the smartphone and the PC it was connected to. By checking the identification data received from the connected device, the hackers were able to discover what device model the victim was using and to progress their attack with a specifically-chosen exploit. That would not have been as easy to achieve if smartphones did not automatically exchange data with a PC automatically upon connecting to the USB port.
“It is strange to see that nearly two years after the publication of a proof-of-concept demonstrating how a smartphone can be infected though the USB, the concept still works. The security risks here are obvious: if you’re a regular user you can be tracked through your device IDs; your phone could be silently packed with anything from adware to ransomware; and, if you’re a decision-maker in a big company, you could easily become the target of professional hackers,” warns Alexey Komarov, researcher at Kaspersky Lab. “And you don’t even have to be highly-skilled in order to perform such attacks, all the information you need can easily be found on the Internet,” he concludes.
In order to protect yourself from the risk of possible attack through unknown charging points and untrusted computers, Kaspersky Lab advises the following:
· Use only trusted USB charging points and computers to charge your device;
· Protect your mobile phone with a password, or with another method such as fingerprint recognition, and don’t unlock it while charging;
· Use encryption technologies and secure containers (protected areas on mobile devices used to isolate sensitive information) to protect the data;
· Protect both your mobile device and your PC/Mac from malware with the help of a proven security solution. This will help to detect malware even if a “charging” vulnerability is used.
Millennials turning 40: NOW will you stop targeting them?
It’s one of the most overused terms in youth marketing, and probably the most inaccurate, writes ARTHUR GOLDSTUCK
One of the most irritating buzzwords embraced by marketers in recent years is the term “millennial”. Most are clueless about its true meaning, and use it as a supposedly cool synonym for “young adults”. The flaw in this targeting – and the word “flaw” here is like calling the Grand Canyon a trench – is that it utterly ignores the meaning of the term. “Millennials” are formally defined as anyone born from 1980 to 2000, meaning they have typically come of age after the dawn of the millennium, or during the 21st century.
Think about that for a moment. Next year, the millennial will be formally defined as anyone aged from 20 to 40. So here you have an entire advertising, marketing and public relations industry hanging onto a cool definition, while in effect arguing that 40-year-olds are youths who want the same thing as newly-minted university graduates or job entrants.
When the communications industry discovers just how embarrassing its glib use of the term really is, it will no doubt pivot – millennial-speak for “changing your business model when it proves to be a disaster, but you still appear to be cool” – to the next big thing in generational theory.
That next big thing is currently Generation Z, or people born after the turn of the century. It’s very convenient to lump them all together and claim they have a different set of values and expectations to those who went before. Allegedly, they are engaged in a quest for experience, compared to millennials – the 19-year-olds and 39-olds alike – supposedly all on a quest for relevance.
In reality, all are part of Generation #, latching onto the latest hashtag trend that sweeps social media, desperate to go viral if they are producers of social content, desperate to have caught onto the trend before their peers.
The irony is that marketers’ quest for cutting edge target markets is, in reality, a hangover from the days when there was no such thing as generational theory, and marketing was all about clearly defined target markets. In the era of big data and mass personalization, that idea seems rather quaint.
Indeed, according to Grant Lapping, managing director of DataCore Media, it no longer matters who brands think their target market is.
“The reason for this is simple: with the technology and data digital marketers have access to today, we no longer need to limit our potential target audience to a set of personas or segments derived through customer research. While this type of customer segmentation was – and remains – important for engagements across traditional above-the-line engagements in mass media, digital marketing gives us the tools we need to target customers on a far more granular and personalised level.
“Where customer research gives us an indication of who the audience is, data can tell us exactly what they want and how they may behave.”
Netflix, he points out, is an example of a company that is changing its industry by avoiding audience segmentation, once the holy grail of entertainment.
In other words, it understands that 20-year-olds and 40-year-olds are very different – but so is everyone in between.

Robots coming to IFA
Robotics is no longer about mechanical humanoids, but rather becoming an interface between man and machine. That is a key message being delivered at next month’s IFA consumer electronics expo in Berlin. An entire hall will be devoted to IFA Next, which will not only offer a look into the future, but also show what form it will take.
The concepts are as varied as the exhibitors themselves. However, there are similarities in the various products, some more human than others, in the fascinating ways in which they establish a link between fun, learning and programming. In many cases, they are aimed at children and young people.
The following will be among the exhibitors making Hall 26 a must-visit:
Leju Robotics (Stand 115) from China is featuring what we all imagine a robot to be. The bipedal Aelos 1s can walk, dance and play football. And in carrying out all these actions it responds to spoken commands. But it also challenges young researchers to apply their creativity in programming it and teaching it new actions. And conversely, it also imparts scholastic knowledge.
Cubroid (Stand 231, KIRIA) from Korea starts off by promoting an independent approach to the way it deals with tasks. Multi-functional cubes, glowing as they play music, or equipped with a tiny rotating motor, join together like Lego pieces. Configuration and programming are thus combined, providing a basic idea of what constitutes artificial intelligence.
Spain is represented by Ebotics (Stand 218). This company is presenting an entire portfolio of building components, including the “Mint” educational program. The modular system explains about modern construction, programming and the entire field of robotics.
Elematec Corporation (Stand 208) from Japan is presenting the two-armed SCARA, which is not intended to deal with any tasks, but in particular to assist people with their work.
Everybot (Stand 231, KIRIA) from Japan approaches the concept of robotics by introducing an autonomous floor-cleaning machine, similar to a robot vacuum cleaner.
And Segway (Stand 222) is using a number of products to explain the modern approach to battery-powered locomotion.
IFA will take place at the Berlin Exhibition Grounds (ExpoCenter City) from 6 to 11 September 2019. For more information, visit www.ifa-berlin.com
