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.

Prof Melanie Walker, Senior Research Professor at the University of the Free State’s (UFS) Centre for Research on Higher Education and Development (CRHED) has received an A1 rating from the National Research Foundation (NRF). This rating acknowledges Prof Walker as a leading international researcher – her work unequivocally recognised by peers world-wide for its high quality and wide impact.

This is the first time in our institution’s history that two A-ratings are awarded simultaneously. Prof Maxim Finkelstein from the Department of Mathematical Statistics also recently received an A2-rating in Probability and Statistics from the NRF.

“Achieving this outstanding rating,” Prof Walker says, “is not just an individual achievement. I have had tremendous personal support and rich intellectual collaborations from wonderful colleagues on the way. The award also recognises the Rector’s project to build a dynamic research culture at UFS.”

Prof Walker has been researching and writing about issues in education and higher education for over 20 years. In particular she is interested in opportunities into, through and beyond education across dimensions of dis/advantage, and how higher education contributes to building a decent society by removing inequalities in its own policies and processes.

Through her focus on capacity building – around the common theme of higher education, human development and social justice – Prof Walker is developing a dynamic cohort of new-generation scholars. Her research group of graduate students and post-doctoral fellows is drawn from countries not only in Africa, but as far afield as Finland, India and Vietnam.

Her networks attract international scholars to the UFS, who contribute to research projects, engage graduate students, and add a considerable contribution to research at our university.

In addition, Prof Walker fulfils a host of roles, which includes:

• Tier One National Research Foundation (NRF) Chair in Higher Education and Human Development.
• Vice-President of the international Human Development and Capability Association (HDCA).
• Fellow of the Academy of Science of South Africa (ASSAf).
• Honorary professor, University of Nottingham, UK.
