This year has seen ransomeware rock headline across the globe and unfortunately it is not about to go away anytime soon. In fact some believe that we haven’t seen the worst of it yet.
Many businesses – and individuals – were affected by the various cyber-attacks perpetrated in the past six months. Ransomware seems to have taken over the headlines this year, and it’s not going away anytime soon. Ransomware is most likely be a topic that will remain highlighted in the years to come.
The business world is becoming more digitized. Data, systems, apps and networks can be crippled by a ransomware attack, which is catastrophic for any business or organization when these vital systems become interrupted. But it’s not just business that suffers: in this year’s WannaCry attack, 70 000 devices in Britain’s National Health Services were affected with knock-on effects on emergency medical services.
Ransomware has climbed meteorically since it first emerged in the mid-2000s, but the aim has mostly remained the same: to extort money from victims. Important data and files are encrypted, leaving the hacker with the only means to access those files. The victim is then asked to pay a ransom – most often in Bitcoin – in order to receive a decryption key so that they can retrieve their files safely.
“In the beginning, many of the ransomware attacks were actually very convincing hoaxes. Other cyber attackers used screen locks so all the victim could see was the notification window. These days, the ransomware that’s out there not only locks information and data, but can also potentially delete encrypted files after a specified time period,” explains Anvee Alderton, channel manager at Trend Micro Southern Africa.
According to Trend Micro, there were 29 different ransomware families in 2015. Just a year later, 247 families emerged – that’s a 752% increase. The hackers have indeed profited from their attacks, raking in millions of dollars by attacking big businesses without data back ups. In the first few months of 2017, ransomware attacks climbed a further 250%.
These attacks are on track to reach another milestone this year as seen in another report, ransomware attacks rose 250 percent during the first few months of 2017, with many infections centered around the U.S.
“We at Trend Micro believe that the ransomware strategy used by hackers will evolve in the not too distant future. Given the amount of new ransomware we hear about regularly, there will be new ransomware samples that will emerge. The sad thing is that there are a lot more attacks focusing on the healthcare industry these days, because of the valuable patient data they have. These attacks on healthcare providers might increase, too,” Alderton predicts.
This may sound as though we are heading towards a ransomware apocalypse, however the good news is that law enforcement is making strides towards catching up with cyber criminals. Various law enforcement organisations have begun to collaborate with other groups such as Cyber Threat and No More Ransomware in order to identify the sources of powerful ransomware, and prevent attacks.
The first port of call for diffusing cyber attacks remains in the hands of an organisations’ staff. Employees should be made aware of the risks of ransomware and understand how infection is delivered and to report any suspicious activity. Access to sensitive data must be limited and patches and backups need to be done regularly and consistently.
“Security solutions also need to incorporate a cross-generational technology approach. This means reputation-based analysis with other capabilities like whitelisting and application control, behavioral analysis, network monitoring, vulnerability shielding, and high-fidelity machine learning. This is the optimal way to protect your business or organisation,” Alderton says.
Android Go puts reliable smartphones in budget pockets
Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.
Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.
Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps.
Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.
Vodafone Smart Kicka 4
At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.
The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018.
Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games.
Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.
Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer.
The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past.
Huawei Y3 (2018)
The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are.
Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.
Comparing the 3
All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker.
Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.
SA gets digital archive
As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.
The southafrica.co.za site carries content about the country’s collective heritage in South Africa’s eleven official languages.
Designed as a nation building, educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.
The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.
At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.
Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.
“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.
Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island. The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
