Ransomware is on the increase and it is costing companies billions in fines due to loss of data and cleanup costs. How can you safeguard your corporation?
Ransomware attacks are on the rise, costing organizations billions of dollars in paid ransoms and cleanup costs, while crippling employee productivity and customer service during the down times. The FBI reports that ransomware attacks cost victims $209 million in the first three months of the year, which is about $330 000 an incident. And, almost 40% of enterprises have been hit by ransomware in the last year.
So, what is ransomware? It’s a strain of malware (malicious software) that cybercriminals upload onto organizations’ computers, servers or user devices and lock them down, before demanding payment of a ransom – usually in the form of Bitcoin or some other non-traceable currency – in exchange for decrypting and releasing their data. In a ransomware attack, the hacker is literally holding your users’ workday hostage, cutting off access to vital productivity tools like email, calendars and contact lists or back-end systems such as databases, file servers, email servers and other systems. What’s worse, 99% of ransomware attacks start with an email message, often enabled via phishing.
Unfortunately there isn’t much information about the threat landscape in South Africa but according to the U.S. government, ransomware attacks in America have increased in frequency by 300% year-on-year in 2016, with 4 000 incidents a day now being reported – AND that is just the U.S.
Ransomware is also not exclusive to big businesses, in fact many smaller organizations are being targeted because they are ‘easy targets’ who may not have deployed the latest security technology or have a dedicated person managing their malicious inbound emails.
- Ransomware cybercrime kits are readily accessible (for as little as $39) on the black market, and thus non-technical cybercriminals can easily license them and deploy them. All you need is an email address and an attack is born.
- There is no single “ransomware security product.” Since no single product can provide adequate protection because of the multifaceted nature of ransomware and the creativity of the attackers who wield it, protection from ransomware must also be multi-faceted.
- Once a ransomware attack happens:
- Organizations suffer from crippled productivity.
- Employees are locked out of vital productivity tools like email, calendars and contact lists as well as other applications and files on affected systems.
- Customers are often impacted because customer-facing operations that are highly dependent on IT are not functional.
- Organizations often succumb to the pressure to pay the ransom to regain access to their applications and data, motivating and financing attackers to expand their ransomware campaigns.
- Recovery can be difficult and time consuming.
- Data can be lost, damaged or corrupted after an attack, as not all ransomware is bug- free. And, in some cases, the attackers, if not paid in a timely manner, will destroy the decryption keys in retribution.
- Organizations suffer from crippled productivity.
A service like Mimecast can tackle ransomware with a layered solution. By bringing together security, continuity and data replication capabilities in a single cloud solution, customers can:
- Prevent an email-borne ransomware attack.
- Ensure that employees can continue to work with email during an attack.
- Store your data in a third-party archive so it’s not lost forever after an attack.
“Cybercriminals are becoming increasingly more sophisticated and insidious. They are constantly revising, updating and re-inventing their tactics and technologies to launch attacks”, says Brandon Bekker, MD of Mimecast Middle East and Africa. As a result, preventive systems, such as antivirus and intrusion prevention systems, are no longer sufficient.
“It’s time for organizations to implement a total cyber resilience strategy that includes security, continuity and data replication,” Bekker continues.
The ideal approach is to layer state-of-the-art preventive systems, point-in-time recovery measures, and a means to maintain business continuity during a ransomware attack. “And don’t forget about the human defense: Employees need to be educated and aware of the different (and evolving) strains of cyberattacks so they can be an effective line of defense.”
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.
