The weekend's IT attacks were extensive, but both companies and individuals are at risk of being attacked by hackers.
To protect yourself from online security threats, it is important to think about where and with whom you share your information, says Marcus Murray.
- When you upload your information on a website, you give your trust to them to manage it.
That information is just as exposed as their security capabilities.
According to him, it is a good sign when companies and services talk about their security work.
One of the most common ways private individuals get hacked is through hacked social media profiles.
Marcus Murray says that an easy way to protect yourself there is to use multi-factor login if it's an option.
- Then you are suddenly one of those who are very difficult to attack.
