The IT landscape is changing at a rapid rate, leaving many CIOs scrambling to keep up. This makes it easy for cybercriminals to exploit flaws in an organisation’s legacy systems, writes BRANDON BEKKER, MD of Mimecast South Africa.
The IT security landscape is changing at a rapid pace, leaving security professionals scrambling to keep up. There is a lucrative industry for stolen private data, not to mention extortion with attacks like ransomware and so-called CEO fraud. Cybercriminals are making money hand over fist by exploiting flaws within organisations’ technology and processes.
CEO fraud or whaling is a highly targeted form of email spear-phishing. Here the criminal sends an email that appears to be from an individual or business that you know (often the CEO or CFO), the kind of person unlikely to be challenged to identify themselves properly. By impersonating your boss, cybercriminals use email to get you to send valuable data or wire funds to them.
Ransomware uses malware that prevents or limits users from accessing their systems, forcing them to pay a ransom through certain online payment methods. Only once they have done this will they be able to access their systems or get their private data back.
These types of malicious attacks exploit human frailty. The criminals know that computers don’t make mistakes, people do. So as technical defences have strengthened, they are turning to the people in front of the technology and exploiting them instead. They know that a successful attack on employees means they can effectively circumnavigate your traditional technical protections – a simple spear-phishing email with a malicious attachment or web link can open up your systems to further attack.
Cybercriminals know they can take advantage of the fact that employees often lack even basic cybersecurity awareness, making them vulnerable to well-crafted social engineering attacks like spear-phishing. So if you run a business (or its IT security) this targeted attack on your employees needs to be taken as seriously as an attack on your technology. Invest in technology and technical resources, but don’t forget staff training.
Dimension Data’s 2015 Global Threat Intelligence Report showed that attacks against businesses and professional services increased from 9% to 15% last year. The rise in threats, such as ransomware and spear-phishing, have seen cybercriminals cashing in, while businesses are left to deal with the devastation.
Cybercrime statistics posted by the South African Banking Risk Information Centre (SABRIC) reveal that South Africans lose in excess of R2.2 billion to internet fraud annually. The statistics have pegged South Africa as the most targeted country on the African continent.
So, just how much are cybercriminals making? A lot. The Cisco 2016 Annual Security Report has pointed out that attackers make around $34 million (nearly R546 million) in gross yearly income through ransomware per campaign. And the FBI reported losses due to CEO fraud or whaling in excess of $2 billion in under two years. And these are losses recorded from just two ‘emerging’ attack strategies.
Keeping the bad guys out means building a human firewall around your business and its data, to match the capabilities of your IT firewall.
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.
