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.

Double achievement for Prof. Paul Grobler

Early this year, two journal editions appearing almost simultaneously in Europe featured cover photographs based on papers by Prof. Paul Grobler of the Department of Genetics and his collaborators.

These papers stem from collaborations with Prof. Gunther Hartl at the University of Kiel (Germany) and Dr Frank Zachos from the Natural History Museum in Vienna (Austria). Both papers cover aspects of the genetics of southern African antelope species.

The first paper appeared in the Journal of Zoological Systematics and Evolutionary Research” (from the Wiley-Blackwell group). This was titled “Genetic structure of the common impala (Aepyceros melampus melampus) in South Africa: phylogeography and implications for conservation”.

In this paper, the team analysed impala from various localities in South Africa to determine the relationship between distribution and genetic structure. The results suggest a clear relationship between genetic characteristics and habitat features that regulate gene flow.

The second appeared in the journal Mammalian Biology (from the Elsevier group), with the title “Genetic analysis of southern African gemsbok (Oryx gazella), reveals high variability, distinct lineages and strong divergence from the East African Oryx beisa”.

Here, the researchers looked at various aspects of the genetics and classification of gemsbok. Among the notable findings is that gemsbok populations on the game farms studied are less inbred than previously predicted.

Proffs. Grobler and Hartl initiated these projects on gemsbok and impala, with sub-sections of the research later completed as M.Sc. projects by students from both South Africa and Germany.

Prof. Grobler has been involved with aspects of the population genetics of various mammal species since the early 1990s, and continued with this line of research after joining the UFS in 2006. Current projects in this field include work on wildebeest, vervet monkeys and white rhinoceroses.
