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.

Three minutes for research

2015-08-19

Sixty-three researchers, three minutes each. This is the Three-Minute-Thesis competition (3MT) for master’s and doctoral students countrywide, presented by the Postgraduate School at the University of the Free State.

For the first time, this international competition will be presented on a national level in South Africa, with students from more than ten of the most prominent universities in the country taking part. During the competition, each researcher has to give a presentation on his/her research in three minutes.

Mr Katleho Nyaile, the competition organiser, says the 3MT is part of the Postgraduate School’s initiative to highlight and to boost postgraduate research.

The 3MT competition originated at the University of Queensland, Australia. Since its inception in 2010, it has developed into an international trend. Currently, the 3MT is presented in Australia, the USA, and the UK.

For the competition, participants are given only three minutes to explain their research. In this short time, they have to explain not only the problem and the methodology, but also why this research is important. Participants are allowed to make use of only one piece of static imaging material for support.

“It is not only great fun, but also a learning opportunity for the researchers. The competition supports the capacity of the researchers to convey the essence of their theses effectively. This is something that researchers sometimes find very difficult.”
