How (over)sharing on social media can trip you up

Profuse recounting of details from your life via social media may come at a price. The more information you pour into the online world, the more at risk you are to spilling information that may put you in attackers’ sights, writes CAREY VAN VLAANDEREN, CEO of ESET Southern Africa.

Ours is a sharing era. Social networking sites have opened up new ways of sharing all kinds of private information, so much so that the divulgation of a variety of personal details on the internet has become second nature to many users.

To be sure, the urge to share is nothing new. This behavior reflects and harnesses a strong human desire to connect with others, which runs deep in our evolutionary past. Arguably, then, the trouble does not lie so much with digital sharing per se. Rather, it boils down to what kind of information we share and, even more strikingly, who can access it.

Many users are oblivious to the risks to which they may expose themselves by sharing personal, if seemingly innocuous, information on social platforms. The same goes for applying little to no restrictions on who can see their activities on networking sites. In addition, social media users tend to use more than one such channel. As a result, attackers can build a fairly rich profile of their target by piecing together information gleaned from the target’s profiles and activities on various networking sites.

Oversaturated with personal information, social media have become perfect hunting ground for malefactors. Having used such a site or sites as a reconnaissance tool, attackers can send you a targeted message that entices you into visiting a bogus website that looks and feels much like the legitimate one in order to steal your credentials and money. Or they can manipulate you into opening a malware-laced attachment acting as a dropper for other malware that can then go on to do all sorts of things, including exfiltrating data or recording keystrokes.

Such missives can be highly tailored and can evoke the impression of being sent from a friend or co-worker. It is little wonder, then, that they have proven to be more successful than spray-and-pray tactics.

Blurring the picture further, the concept of networking that lies at the heart of social platforms contributes to a decreased sense of caution. Many people let their guard down and are more likely, for example, to click malicious links sent via social media than those received in an email.

To be sure, social engineering techniques predate the advent of online social platforms. However, with online networking, they have taken on whole new vigor and opened up new avenues for identity theft, online fraud, and other crimes.

Human-factor precautions

What are some of the measures you can take to counter risks stemming from digital (over)sharing?

To start off, you may want to review regularly and make the best use of the privacy settings available on your social network(s) of choice. Importantly, whenever possible, you are well advised to limit the circle of people who can see what you’re up to.

Notwithstanding such restrictions, however, there is still some risk that your private information can be exposed to prying eyes. In fact, as soon as you post something, you have no control over what others do with it.

With that in mind, you may want to limit information that you post or upload, especially the kind of information that could make you vulnerable. It’s safer not to post anything that you wouldn’t want the public to see. Put yourself in attackers’ shoes: could the information you divulge help them hurt you? If so, you may not want to share it.

Beware suspicious or too-good-to-be-true messages and links. That applies even if the message appears to come from one of your friends, as that could well come from an attacker after he has broken into your friend’s account. Ne’er-do-wells know too well that the more credibility they can provide for their shenanigans, the juicier the rewards.

Also, be skeptical of strangers wanting to be your online friends. Ideally, accept only friendship or connection requests from people you know in real life. The internet is rife with fraudsters intent on bilking money out of you via all manner of ploys. Or they can simply burglarize your home in an old-fashioned style after you tell the world about your vacation, leaving your abode empty and ripe for the picking.

At heart, this all is a human vs. human problem, which highlights how this can be countered – by being more security-aware. “On the Internet, nobody knows you’re a dog”, as the adage that captures the spirit of online privacy and anonymity goes. We were made to be social, but let’s socialize responsibly.

Samsung in lock-step with its rivals?

Tonight Samsung will kick off the next round in the smartphone wars with the S10 range, writes ARTHUR GOLDSTUCK.

Published

on

When Samsung unveils the new S10 smartphone at an event in San Francisco today, it will mark the beginning of the 2019 round of World War S. That stands for smartphone wars, although Samsung would like it to be all about the S.

Ever since the launch of the Samsung Galaxy S4 in 2013, Samsung has held both technology and thought leadership in the handset world. Back then, Apple’s iPhone 5 was the last device from the American manufacturer that could lay claim to being the best smartphone in the world. With the 2013 launch of the iPhone 5s, Apple entered an era of incremental improvement, playing catch-up, and succumbing to market trends driven by its competitors.

Six years later, Samsung is fighting off the same threat. Its Chinese rival, Huawei, suddenly wrested away leadership in the past year, with the P20 Pro and Mate 20 Pro regarded as at last equal to the Samsung Galaxy S9 Plus and Galaxy Note 9 – if not superior. Certainly, from a cost perspective, Huawei took the lead with its more competitive prices, and therefore more value for money.

Huawei also succeeded where Apple failed: introducing more economical versions of its flagship phones. The iPhone 5c, SE and XR have all been disappointments in the sales department, mainly because the price difference was not massive enough to attract lower-income users. In contrast, the Lite editions of the Huawei P9, P10 and P20 have been huge successes, especially in South Africa.

Today, for the first time in half a decade, Samsung goes into battle on a field laid out by its competitors. It is expected to launch the Galaxy S10 Plus, S10 and S10 e, with the latter being the Samsung answer to the strategy of the iPhone XR and Huawei P20 Lite.

Does this mean Samsung is now in lock-step with its rivals, focused on matching their strategies rather than running ahead of them?

It may seem that way, but Samsung has a few tricks up its electronic sleeve. For example, it is possible it will use the S10 launch to announce its coming range of foldable phones, expected to be called the Galaxy X, Galaxy F, Galaxy Fold or Galaxy Flex. It previewed the technology at a developer conference in San Francisco last November, and this will be the ideal moment to reclaim technology leadership by going into production with foldables – even if the S10 range itself does not shoot out the lights.

However, the S10 handsets will look very different to their predecessors. First, before switching on the phone, they will be notable by the introduction of what is being called the punch-hole display, which breaks away from the current trend of having a notch at the top of the phone to house front-facing cameras and speakers. Instead, the punch-hole is a single round cut-out that will contain the front camera. It is the key element of Samsung’s “Infinity O” display – the O represents the punchhole – which will be the first truly edge-to-edge display, on the sides and top.

The S10 range will use the new Samsung user interface, One UI, also unveiled at the developer conference. It replaces the previous “skin”, unimaginatively called the Samsung Experience, to introduce a strong new interface brand.

One UI went live on the Note 8 last month, giving us a foretaste, and giving Samsung a chance to iron out the bugs in the field. It is a less cluttered interface, addressing one of the biggest complaints about most manufacturer skins. Only Nokia and Google Pixel handsets offer pure Android in the local market, but One UI is Samsung’s best compromise yet.

It introduces a new interaction area, in the bottom half, reachable with the thumb, with a viewing area at the top, allowing the user to work one-handed on the bottom area while still having apps or related content visible above. One UI also improves gesture navigation – the phone picks up hand movements without being touched – and notification management.

The S10 range will be the first phones to feature the latest Qualcomm Snapdragon 855 chip, at least for the South African and American markets. That makes it 5G compatible, for when this next generation of mobile broadband becomes available in these markets.

They will also be the first phones to feature Wi-Fi 6, the next generation of the Wi-Fi mobile wireless standard. It will perform better in congested areas, and data transfer will be up to 40% faster than the previous generation.

The phones will be the first to use ultrasound for fingerprint detection. If Samsung gets it right, this will make it the fastest in-screen fingerprint sensor on the market, and allows for a little leeway if one pushes the finger down slightly outside the fingerprint reader surface. It does mean, however, that screen protectors will have to be redesigned to avoid blocking the detection.

Not enough firsts? There are a few more.

Most notably, it will be the first phone range to feature 1 Terabyte (TB) storage – that’s a thousand Gigabytes (GB) – at least for the top-of-the-range devices. Samsung last month announced that it would be the first manufacturer to make 1TB built-in onboard flash storage. Today, it will deploy this massive advantage as it once again weaponises its technology in the fight for smartphone domination.

IoT set to improve authentication

Published

on

By Sherry Zameer, Senior Vice President, Internet of Things Solutions for CISMEA region at Gemalto

As it rapidly approaches maturity, the Internet of Things (IoT) is set to continue a transformational trajectory, introducing new efficiencies in multiple fields by allowing measurement and analysis on a scale that has never been possible before. From agriculture to logistics, from retail to hospitality, from traffic to health, from the home to the office, the applications for monitoring ”things” are limited only by the imagination.

And South African (and African) businesses are showing abundant imagination in their practical deployments of IoT solutions in multiple settings, creating a better tomorrow through almost universal measurement and the introduction of new levels of convenience – including how to access locations, devices and services securely.

Any company, whether South African or international, should bear in mind that understanding consumer expectations can be the key to unlocking the full potential of IoT devices and related smart services.

According to Gemalto’s latest Connected Living study, improving the way consumers authenticate themselves to services is one of the most anticipated benefits of IoT, highlighting a desire for a more seamless and secure IoT experience.

Consumers are interested in advanced ways of authenticating themselves through automatic (based on behavioral patterns) or biometric techniques, lessening the need to have to intervene manually, all in the name of a much more streamlined authentication process. Smartphone manufacturers like Apple and Samsung have already placed fingerprint and facial recognition high on the agenda. There is also a widespread positive sentiment towards IoT’s potential for improving the quality of home life through connected, smart appliances.

Personalised services is something else that wins consumers over. In fact, a fluid, personalised and unified experience with continuity of services, together with security and privacy, is critical for the successful implementation of any technology.

And those types of services are today quite possible. With everything being connected – from small gadgets to digital solutions for large enterprises – IoT is no longer just a buzzword. That much is clear in a piece from Vodacom IoT managing executive Deon Liebenberg. Writing for IOL Online, Liebenberg provides insight into the sheer range of applications for IoT: the 20 use cases he cites range from the obvious, like transport and logistics, to the connected home and wearables; he even suggests tagging pets with IoT transmitters, for those who always need to know the whereabouts of the family cat.

Low-cost tags fitted to cats, dogs, lamp posts, shipping containers or other items are just one part of the puzzle, however. There are other two pieces; arguably the most complex part is the availability of communication networks in areas where there aren’t any WiFi networks, or indeed, anything else.

And that’s where the bigger takeaway from Liebenberg’s piece and other IoT trends articles becomes apparent. The communication networks are there, as are those tags: dedicated IoT networks (like LoraWAN, SigFox and narrowband IoT) are all available in South Africa.

So, too, is the third and final essential component. Software which is able to process the data generated by the tag and transmitted over the IoT network and into the internet. In this regard, there’s no shortage of solutions available from cloud providers like AWS and Azure; electronics giant Siemens, too, is in on the action, having recently launched a new cloud-based IoT operating system to develop applications and services for process industries, including oil and gas and water management.

This combination means it is quite possible right now to enable just about any use case. Business owners, who will know best how IoT can add value in their organisation, can now see their ideas becoming reality. Most crucial of all, IoT solutions delivering new levels of efficiency and convenience are not only possible, they are able to be offered with the simple and effective security that will drive consumer acceptance.
