Don’t get hacked; protect your WhatsApp account

Whatsapp security — It is important to be safe when using WhatsApp. Do not leave your phone unattended when you are not close by.

There are 2 billion WhatsApp users in the world, and 1,6 billion WhatsApp users access their accounts on a daily basis.

However, it is important to also be safe when using this popular communication tool.

According to Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison in Protection Services, it does happen that people’s WhatsApp accounts get hacked; this is a serious violation of privacy.

“It means a third party now has unlimited access to your personal chats, information, media – and in some instances, they can also masquerade as you by deleting your chats, replying to your chats, and committing crimes. That’s just the tip of the iceberg of how harmful it can be to get hacked,” says Van Jaarsveld.

He adds: “Hackers can access your WhatsApp data by various means, e.g. via WhatsApp web or registering your number on another device.

The South African Police Service (SAPS) provided the following tips to prevent one’s WhatsApp from getting hacked:

• Log out from all computers that you see in the list under WhatsApp Web. This will stop hackers from further reading your chats. However, this should be done every time you use WhatsApp web.
• Do not leave your phone unattended when you are out.
• Lock all your apps to prevent unknown people from accessing your apps.
• Do not connect your phone to unknown Wi-Fi connections, as hackers can also use the unique MAC address to access all your WhatsApp chats.
• In case your WhatsApp has already been hacked, deactivate your account by emailing support@whatsapp.com. Your account will be automatically deleted if not accessed for 30 days.
• Enable two-step verification under your WhatsApp account settings. This will add an extra layer of security to the app.
• Lock WhatsApp. It is imperative to have the AppLocker that will help you lock your WhatsApp. While WhatsApp does not offer this application per se, you can download it and the app will facilitate the use of your WhatsApp with a password or PIN. This will help to prevent anyone who has access to your phone from accessing your WhatsApp account, since they will require a password to open it.

UFS Department of Computer Science and Informatics motivates programming success among learners

2015-04-23

From Sentraal High School are from the left: Albert Dreyer (full marks, Grade 9); Corlé van der Walt (full marks, Grade 10); Janco Venter (full marks, Grade 10); Soné du Pisanie (full marks, Grade 10) en Handré Venter (Grade 9).

A group of learners from the Free State, who are taught at and by the University of the Free State’s Department of Computer Science and Informatics (under the Python project), came first in the Talent Search round of the South African Computer Olympiad (SACO).

According to Dr Anelize van Biljon, senior lecturer in the Department of Computer Science and Informatics, the Olympiad is presented in three main rounds: the Talent Search, the Application Olympiad, and the Programming Olympiad.

At the UFS’s Department of Computer Science and Informatics’ Python project, pupils from various schools in Bloemfontein attend programming classes where they are taught by staff and students of the department. These students are benefitted by the opportunity to transfer their knowledge to others. All the classes are free of charge.

Anelize explains: “The name was chosen because we use the Python programming language. It is a language with considerable appeal – not one of the fastest – which can be learnt relatively quickly, and which conforms to SACO requirements. The purpose of this programming is to implement algorithms (the learner is given a problem, makes a plan to solve it, and does the necessary programming). Thus, it is not about the looks of the programme, but about its effectiveness and speed.”
Anelize is the initialiser and co-ordinator of the Python project. "I started this project in 2010 in the Department of Computer Science and Informatics for learners from Grades 6 to 12 to encourage them to take the subject. These classes exposed them to something more than school work. I enjoy this kind of competitions and am also very involved with Maths Olympiads.

Achievements such as these are good advertisements for the Department of Computer Science and Informatics,” she said.
