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.

How to interpret Centlec’s load shedding

2008-01-31

Everyone in South Africa is affected by power failures (load shedding). Centlec took certain measures to manage the situation. These measures are explained:

Time slots
See the following table for an indication of times when load shedding might be applied to specific areas: http://www.centlec.co.za/power_shed/PDF/time_slots.pdf

Groups
The city was divided into six groups. This document clearly indicates which area in the city resorts under which group: http://www.centlec.co.za/power_shed/PDF/groups.pdf

According to the document, the university resorts under group 4. In the table with time slots it is the grey area.

Stages
Eskom developed three stages for load shedding. (See stage table at the bottom of the page http://www.centlec.co.za/power_shed/PDF/time_slots.pdf)
- Stage 1: Less load shedding is applied in stage 1. E.g. the UFS resorts in group 4 and on a Monday, according to stage 1, the power will not be switched off during 12:00 and 14:30 (this time slot is not highlighted in orange).
- Stage 2: More load shedding is applied in stage 2. Load shedding will be applied during stage 2 between 12:00 and 14:30 on a Monday at the UFS.
- Stage 3: All time slots are highlighted in orange, which indicates that power will be switched off for the whole duration of stage 3.

Example
Today, Tuesday, load shedding was scheduled to take place from 10:00 to 12:00 at the UFS. Currently, according to Centlec’s web site, stage 1 is active. This time slot is not marked in stage 1, therefore load shedding is not applied. Centlec gives also additional information; “No load shedding in progress.”

Keep in mind that if an area is at risk it does not automatically imply that the power will be switched off. It all depends on the request from Eskom at that particular moment whether the actual shedding is required.
