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.

“Preparing and presenting an inaugural lecture is an opportunity to look back at one’s career and to enjoy previous highlights and achievements; to share these, not only with colleagues, but also with family and friends.”

This is according to Prof Felicity Burt, who recently presented her inaugural lecture, Catching a Virus. Prof Burt is a professor in medical virology in the Faculty of Health Sciences at the University of the Free State (UFS). It may sound ominous, but it is a story about identifying viruses, and finding and stopping them in their tracks in nature.

Research focus on arbo- and zoonotic viruses 
“My research focuses on arboviruses and zoonotic viruses,” said Prof Burt. “Arboviruses are viruses that are transmitted by insect vectors, such as mosquitoes, ticks, midges or sandflies, whereas zoonotic viruses are naturally transmitted from animals to humans. However, there is a considerable overlap between these two groups.” The research looks at host responses, virus discovery and surveillance in order to identify which of the viruses in circulation have the potential to cause human diseases.

“Emerging and re-emerging viruses have significant implications for public health,” said Prof Burt at the start of her lecture. She also stated that there have been disease outbreaks of unprecedented magnitude, which have spread and established in distinct geographic regions. “Many of these emerging viruses are transmitted by vectors or are spread to humans from animals. These viruses can cause significant diseases in humans,” said Prof Burt. 

There are many reasons why these viruses re-emerge, such as global warming, human invasion in forested areas, changes in agricultural practices, international travel, as well as the illegal movement of animals. Prof Burt used the Zika virus as an example of a recent emerging virus. 

More than 20 years’ experience 

With more than 20 years’ experience and a PhD in medical virology from the University of the Witwatersrand, Prof Burt is a renowned specialist. She has worked in the Special Pathogens Unit at the National Institute for Communicable Diseases, and was a member of various teams responding to outbreaks of Ebola and Rift Valley fever in Africa and Saudi Arabia, respectively. She is co-author of more than 51 articles in international scientific journals, as well as six chapters on arboviruses. In 2016, she was awarded a SARChl research chair by the South African Research Chair Initiative for her research on vector-borne and zoonotic diseases.
