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.


Online retail gets real

After decades of experience in selling online, retailers still seek out the secret of reaching the digital consumer, writes ARTHUR GOLDSTUCK.



It’s been 23 years since the first pizza and the first bunch of flowers was sold online. One would think, after all this time, that retailers would know exactly what works, and exactly how the digital consumer thinks.

Yet, in shopping-mad South Africa, only 4% of adults regularly shop online. One could blame high data costs, low levels of tech-savviness, or lack of trust. However, that doesn’t explain why a population where more than a quarter of people have a debit or credit card and almost 40% of people use the Internet is staying away.

The new Online Retail in South Africa 2019 study, conducted by World Wide Worx with the support of Visa and Platinum Seed, reveals that growth is in fact healthy, but is still coming off a low base. This year, the total sale of retail products online is expected to pass the R14-billion mark, making up 1.4% of total retail.

This figure represents 25% growth over 2017, and comes after the same rate of growth was seen in 2017. At this rate, it is clear that online retail is going mainstream, driven by aggressive marketing, and new shopping channels like mobile shopping. 

But it is equally clear that not all retailers are getting it right. According to the study, the unwillingness of business to reinvest revenue in developing their online presence is one of the main barriers to long-term success. Only one in five companies surveyed invested more than 20% of their online turnover back into their online store. Over half invested less than 10% back.

On the surface, the industry looks healthy, as a surprisingly high 71% of online retailers surveyed say they are profitable. But this brings to mind the early days of, in 1996, when founder Jeff Bezos was asked when it would become profitable.

He declared that it would not be profitable for at least another five years. And if it did, he said, it would be in big trouble. He meant that it was so important for long-term sustainability that Amazon reinvest all its revenues in customer systems, that it could not afford to look for short-term profits.

According to the South African study, the single most critical factor in the success of online retail activities is customer service. A vast majority, 98% of respondents, regarded it as important. This positions customer service as the very heart of online retail. For Amazon, investment back into systems that would streamline customer service became the key to the world’s digital wallets.

In South Africa online still make up a small proportion of overall retail, but for the first time we see the promise of a broader range of businesses in terms of category, size, turnover and employee numbers. This is a sign that our local market is beginning to mature. 

Clothing and apparel is the fastest growing sector, but is also the sector with the highest turnover of businesses. It illustrates the dangers of a low barrier to entry: the survival rate of online stores in this sector is probably directly opposite to the ease of setting up an online apparel store.

A fast-growing category that was fairly low on the agenda in the past, alcohol, tobacco and vaping, has benefited from the increased online supply of vapes, juices and accessories. It also suggests that smoking bans, and the change in the legal status of marijuana during the survey, may have boosted demand. 

In the coming weeks, we can expect online retail to fall under the spotlight as never before. Black Friday, a shopping tradition imported “wholesale” from the United States, is expected to become the biggest online shopping day of the year in South Africa, as it is in the USA.

Initially, it was just a gimmick in South Africa, attempting to cash in on what was a purely American tradition of insane sales on the Friday after Thanksgiving Day, which occurs on the third Thursday of November every year. It is followed by Cyber Monday, making the entire weekend one of major promotions and great bargains.

It has grown every year in South Africa since its first introduction about six years ago, and last year it broke into the mainstream, with numerous high profile retailers embracing it, and many consumers experiencing it for the first time. 

It is now positioned as the prime bargain day of the year for consumers, and many wait in anticipation for it, as they do in the USA. Along with Cyber Monday, it provides an excuse for retailers to go all out in their marketing, and for consumers to storm the display shelves or web pages. South African shoppers, clearly, are easily enticed by bargains.

Word of mouth around Black Friday has also grown massively in the past two years, driven by both media and shoppers who have found ridiculous bargains. As news spreads that the most ridiculous of the bargains are to be had online, even those who were reticent of digital shopping will be tempted to convert.

The Online Retail in SA 2019 report has shown over the years that, as people become more experienced in using the Internet, their propensity to shop online increases. This is part of the World Wide Worx model known as the Digital Participation Curve. The key missing factor in the Curve is that most retailers do not know how to convert that propensity into actual online shopping behaviour. Black Friday will be one of the keys to conversion.

Carry on reading to find out about the online retailers of the year.

Reliable satellite Internet?

MzansiSat, a satellite-Internet business, aims to beam Internet connections to places in South Africa which don’t have access to cabled and mobile network infrastructure, writes BRYAN TURNER.



Stellenbosch-based MzansiSat promises to provide cheap wholesale Internet to Internet Service Providers for as little as R25 per Gigabyte. Providers who offer more expensive Internet services could benefit greatly from partnering with MzansiSat, says the company. 

“Using MzansiSat, we hope that we can carry over cost-savings benefits to the consumer,” says Victor Stephanopoli, MzansiSat chief operating officer.

The company, which has been spun off from StellSat, has been looking to increase its investor portfolio while it waits for spectrum approval. The additional investment will allow MzansiSat’s satellite to operate in more regions across Africa.

The MzansiSat satellite is being built by Thales Alenia Space, a French company which is also acting as technical partner to MzansiSat. In addition to building the satellite, Thales Alenia Space will also be assisting MzansiSat in coordinating the launch. The company intends to launch the satellite into the 56°E orbital slot in a geostationary orbit, which enables communication almost anywhere in Africa. The launch is expected to happen in 2022. 

The satellite will have 76 transponders, 48 of which will be Ku-band and 28 C-band. Ku-band is all about high-speed performance, while C-band deals with weather-resistance. The design intention is for customers of MzansiSat to choose between very cheap, reliable data and very fast, power-efficient data. 

C-band is an older technology, which makes bandwidth cheaper and almost never affected by rain but requires bigger dishes and slower bandwidth compared to Ku-band connections. On the other hand, Ku-band is faster, experiences less microwave interference, and requires less power to run – but is less reliable with bad weather conditions.

MzansiSat’s potential military applications are significant, due to the nature of the military being mobile and possibly in remote areas without connectivity.  Connectivity everywhere would be potentially be life-saving.

Consumers in remote areas will benefit, even though satellite is higher in latency than fibre and LTE connections. While this level of latency is high (a fifth of a second in theory), satellite connections are still adequate for browsing the Internet and watching online content. 

The Internet of Things (IoT) may see the benefits of satellite Internet before consumers do. The applications of IoT in agriculture are vast, from hydration sensors to soil nutrient testers, and can be realised with an Internet connection which is available in a remote area.

Stephanopoli says that e-learning in remote areas can also benefit from MzansiSat’s presence, as many school resources are becoming readily available online. 

“Through our network, the learning experience can be beamed into classrooms across the country to substitute or complement local resources within the South African schooling system.”
