According to Kaspersky Lab, the volume of spam e-mails in 2015 decreased to 55.28% of overall e-mail traffic. The slump can be attributed to the increasing popularity of legal advertising platforms on social networks, and coupon clipping services.
Among other trends identified in the Kaspersky Lab spam report are the following. Over three quarters (79%) of all emails sent were less than 2kb, which shows a steady decrease in email size for spam campaigns over the past few years. Financial institutions such as banks, payment systems and online shops were attacked most often with phishing emails (34.33%, a rise of 5.59%).
In 2015, cybercriminals continued to send out fake emails from mobile devices and notifications from mobile apps containing malware or advertising messages. New tactics included fraudsters spreading malware in the form of .apk (Android executive files) and .jar (ZIP archives containing a programme in Java). In addition, cybercriminals masked a mobile encryption Trojan behind a file containing updates for Flash Player. After launching, the malware encrypted images, documents and video files stored on the device with users receiving a message telling them to pay a fee in order to decrypt the files.
“The increased use of mobile devices in our everyday life to exchange messages and data, as well as access and control bank accounts, has also resulted in increased exploitation opportunities for cybercriminals. Mobile malware and fraudulent spam is becoming more popular and efforts to dupe victims are becoming more sophisticated year on year, with the emergence of apps that can be used by cybercriminals both directly (for sending out spam, including malicious spam) and indirectly (via phishing emails). Mobile device users therefore need to be on their guard and remain vigilant, as cybercriminal activities in this area are only likely to increase, along with our reliance on devices”, warns Daria Loseva, Spam Analysis Expert at Kaspersky Lab.
The US remained the biggest source of spam (15.2%), with second place taken by Russia (6.15%) and China making way for Vietnam in third spot (6.12%). Germany was the biggest victim with 19.06% of spam attacks – a 9.84% increase on 2014, followed by Brazil at 7.64% which posted a 4.09% increase and moved up from sixth place in 2014. Russia moved up to third place from eighth, an increase of 3.06% to 6.03% of all spam attacks in 2015.
Hot spam topics of the year:
Although the Olympic games in Brazil has yet to take place, fraudsters have already started to exploit the event, sending emails announcing false lottery wins and asking the recipient to fill in a form with their personal details. In these attacks, emails with pdf attachments, pictures and other graphical elements were designed to fool the spam filters.
“Nigerian” fraud used the Ukrainian political situation, the Syrian civil war, the election in Nigeria and the earthquake in Nepal to exploit the kindness and empathy of recipients with believable email content. These emails contained content calling for material support for a person in need.
Low-cost wireless sport earphones get a kickstart
Wireless earphone brands are common, but not crowdfunded brands. BRYAN TURNER takes the K Sport Wireless for a run.
As wireless technology becomes better, Bluetooth earphones have become popular in the consumer market. KuaiFit aspires to make them even more accessible to more people through a cheaper, quality product, by selling the K Sport Wireless Earphones directly from its Kickstarter page
KuaiFit has an app by the same name which offers voice-guided personal training services in almost every type of exercise, from cardio to weight-lifting. A vast range of connectivity to third-party sensors is available, like heart rate sensors and GPS devices, which work well with guided coaching.
The app starts off with selecting a fitness level: beginner, intermediate and advanced. Thereafter, one has the ability to connect with real personal trainers via a subscription to its paid service. The subscription comes free for 6 months with the earphones, and R30 per month thereafter.
The box includes a manual, a USB to two USB Type B connectors, different sized soft plastic eartips and the two earphone units. Each earphone is wireless and connects to the other independently of wires. This puts the K Sport Wireless in the realm of the Apple Earpods in terms of connection style.
The earphones are just over 2cm wide and 2cm high. The set is black with a light blue KuaiFit logo on the earphone’s button.
The button functions as an on/off switch when long-pressed and a play/pause button when quick-pressed. The dual-button set-up is convenient in everyday use, allowing for playback control depending on which hand is free. Two connectivity modes are available, single earphone mode or dual earphone mode. The dual earphone mode intelligently connects the second earphone and syncs stereo audio a few seconds after powering on.
In terms of connectivity, the earphones are Bluetooth 4.1 with a massive 10-meter range, provided there are no obstacles between the device and the earphones. While it’s not Bluetooth 5, it still falls into the Bluetooth Low Energy connection category, meaning that the smartphone’s battery won’t be drastically affected by a consistent connection to the earphones. The batteries within the earphones aren’t specifically listed but last anywhere between 3 and 6 hours, depending on the mode.
Audio quality is surprisingly good for earphones at this price point. The headset style is restricted to in-ear due to its small design and probable usage in movement-intensive activities. As a result, one has to be very careful how one puts these earphones, in because bass has the potential of getting reduced from an incorrect in-ear placement. In-ear earphones are usually notorious for ear discomfort and suction pain after extended usage. These earphones are one of the very few in this price range that are comfortable and don’t cause discomfort. The good quality of the soft plastic ear tip is definitely a factor in the high level of comfort of the in-ear earphone experience.
Overall, the K Sport Wireless earphones are great considering the sound quality and the low price: US$30 on Kickstarter.

Taxify enters Google Maps
A recent update to Taxify now uses Google Maps which allows users to identify their drivers, find public transport and search for billing options.
People planning their travel routes using Google Maps will now see a Taxify icon in the app, in addition to the familiar car, public transport, walking and billing options.
Taxify started operating in South Africa in 2016 and as of October 2018 operates in seven South African cities – Johannesburg, Ekurhuleni, Tshwane, Cape Town, Durban, Port Elizabeth and Polokwane.
Once riders have searched for their destination and asked the app for directions, Google Maps shares the proximity of cars on the Taxify platform, as well as an estimated fare for the trip.
If users see that taking the Taxify option is their best bet, they can simply tap on the ‘Open app’ icon, to complete the process of booking the ride. Customers without the app on their device will be prompted to install Taxify first.
This integration makes it possible for users to evaluate which of the private, public or e-hailing modes of transport are most time-efficient and cost-effective.
“This integration with Google Maps makes it so much easier for users to choose the best way to move around their city,” says Gareth Taylor, Taxify’s country manager for South Africa. “They’ll have quick comparisons between estimated arrival times for the different modes of transport, as well as fares they can expect to pay, which will help save both time and money,” he added.
Taxify rides in Google Maps are rolling out globally today and will be available in more than 15 countries, with South Africa being one of the first countries to benefit from this convenient service.
