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.

Our Faculty of Health Sciences hosted the European Association for Cardiothoracic Surgeons Academy (EACTS) and Hannes Meyer Cardiothoracic Surgery Registrar Symposium, from 3 to 5 June 2011.

The focus of this year’s symposium was new techniques in perfusion and surgery, with specific emphasis on research methodology, inflammatory lung disease and cardiac surgery in children and adults, which can be performed without the aid of a heart-lung machine in developing countries.

The symposium was attended by approximately 70 delegates from cardiothoracic units from across South Africa and 10 doctors from 6 African countries, as well as 30 perfusion technologists.

Several international visitors were present, like Prof. Paul Sergeant and Prof. Marko Turina, two previous EACTS presidents and Prof. Charles Yankah, a Ghanaian Cardiothoracic Surgeon from the Charite Medical University in Berlin. The current president of the European Board of Cardiovascular Perfusion (EBCP), Mr Frank Merkle, was also one of three international speakers delivering lectures on perfusion technology.
