Charging phone on public USB can get you hacked

Published

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.

VoD cuts the cord in SA

Some 20% of South Africans who sign up for a subscription video on demand (SVOD) service such as Netflix or Showmax do so with the intention of cancelling their pay television subscription.

That’s according to GfK’s international ViewScape survey*, which this year covers Africa (South Africa, Kenya and Nigeria) for the first time.

The study—which surveyed 1,250 people representative of urban South African adults with Internet access—shows that 90% of the country’s online adults today use at least one online video service and that just over half are paying to view digital online content. The average user spends around 7 hours and two minutes a day consuming video content, with broadcast television accounting for just 42% of the time South Africans spend in front of a screen.

Consumers in South Africa spend nearly as much of their daily viewing time – 39% of the total – watching free digital video sources such as YouTube and Facebook as they do on linear television. People aged 18 to 24 years spend more than eight hours a day watching video content as they tend to spend more time with free digital video than people above their age.

Says Benjamin Ballensiefen, managing director for Sub Sahara Africa at GfK: “The media industry is experiencing a revolution as digital platforms transform viewers’ video consumption behaviour. The GfK ViewScape study is one of the first to not only examine broadcast television consumption in Kenya, Nigeria and South Africa, but also to quantify how linear and online forms of content distribution fit together in the dynamic world of video consumption.”

The study finds that just over a third of South African adults are using streaming video on demand (SVOD) services, with only 16% of SVOD users subscribing to multiple services. Around 23% use per-pay-view platforms such as DSTV Box Office, while about 10% download pirated content from the Internet. Around 82% still sometimes watch content on disc-based media.

“Linear and non-linear television both play significant roles in South Africa’s video landscape, though disruption from digital players poses a growing threat to the incumbents,” says Molemo Moahloli, general manager for media research & regional business development at GfK Sub Sahara Africa. “Among most demographics, usage of paid online content is incremental to consumption of linear television, but there are signs that younger consumers are beginning to substitute SVOD for pay-television subscriptions.”

New data rules raise business trust challenges

When the General Data Protection Regulation comes into effect on May 25th, financial services firms will face a new potential threat to their on-going challenges with building strong customer relationships, writes DARREL ORSMOND, Financial Services Industry Head at SAP Africa.

The regulation – dubbed GDPR for short – is aimed at giving European citizens control back over their personal data. Any firm that creates, stores, manages or transfers personal information of an EU citizen can be held liable under the new regulation. Non-compliance is not an option: the fines are steep, with a maximum penalty of €20-million – or nearly R300-million – for transgressors.

GDPR marks a step toward improved individual rights over large corporates and states that prevents the latter from using and abusing personal information at their discretion. Considering the prevailing trust deficit – one global EY survey found that 60% of global consumers worry about hacking of bank accounts or bank cards, and 58% worry about the amount of personal and private data organisations have about them – the new regulation comes at an opportune time. But it is almost certain to cause disruption to normal business practices when implemented, and therein lies both a threat and an opportunity.

The fundamentals of trust

GDPR is set to tamper with two fundamental factors that can have a detrimental effect on the implicit trust between financial services providers and their customers: firstly, customers will suddenly be challenged to validate that what they thought companies were already doing – storing and managing their personal data in a manner that is respectful of their privacy – is actually happening. Secondly, the outbreak of stories relating to companies mistreating customer data or exposing customers due to security breaches will increase the chances that customers now seek tangible reassurance from their providers that their data is stored correctly.

The recent news of Facebook’s indiscriminate sharing of 50 million of its members’ personal data to an outside firm has not only led to public outcry but could cost the company $2-trillion in fines should the Federal Trade Commission choose to pursue the matter to its fullest extent. The matter of trust also extends beyond personal data: in EY’s 2016 Global Consumer Banking Survey, less than a third of respondents had complete trust that their banks were being transparent about fees and charges.

This is forcing companies to reconsider their role in building and maintaining trust with its customers. In any customer relationship, much is done based on implicit trust. A personal banking customer will enjoy a measure of familiarity that often provides them with some latitude – for example when applying for access to a new service or an overdraft facility – that can save them a lot of time and energy. Under GDPR and South Africa’s POPI act, this process is drastically complicated: banks may now be obliged to obtain permission to share customer data between different business units (for example because they are part of different legal entities and have not expressly received permission). A customer may now allow banks to use their personal data in risk scoring models, but prevent them from determining whether they qualify for private banking services.

What used to happen naturally within standard banking processes may be suddenly constrained by regulation, directly affecting the bank’s relationship with its customers, as well as its ability to upsell to existing customers.

The risk of compliance

Are we moving to an overly bureaucratic world where even the simplest action is subject to a string of onerous processes? Compliance officers are already embedded within every function in a typical financial services institution, as well as at management level. Often the reporting of risk processes sits outside formal line functions and end up going straight to the board. This can have a stifling effect on innovation, with potentially negative consequences for customer service.

A typical banking environment is already creaking under the weight of close to 100 acts, which makes it difficult to take the calculated risks needed to develop and launch innovative new banking products. Entire new industries could now emerge, focusing purely on the matter of compliance and associated litigation. GDPR already requires the services of Data Protection Officers, but the growing complexity of regulatory compliance could add a swathe of new job functions and disciplines. None of this points to the type of innovation that the modern titans of business are renowned for.

A three-step plan of action

So how must banks and other financial services firms respond? I would argue there are three main elements to successfully navigating the immediate impact of the new regulations:

Firstly, ensuring that the technologies you use to secure, manage and store personal data is sufficiently robust. Modern financial services providers have a wealth of customer data at their disposal, including unstructured data from non-traditional sources such as social media. The tools they use to process and safeguard this data needs to be able to withstand the threats posed by potential data breaches and malicious attacks.

Secondly, rethinking the core organisational processes governing their interactions with customers. This includes the internal measures for setting terms and conditions, how customers are informed of their intention to use their data, and how risk is assessed. A customer applying for medical insurance will disclose deeply personal information about themselves to the insurance provider: it is imperative the insurer provides reassurance that the customer’s data will be treated respectfully and with discretion and with their express permission.

Thirdly, financial services firms need to define a core set of principles for how they treat customers and what constitutes fair treatment. This should be an extension of a broader organisational focus on treating customers fairly, and can go some way to repairing the trust deficit between the financial services industry and the customers they serve.
