As the famous idiom goes: “Nothing is certain but death and taxes.” Now, in our digital age, we can add one more certainty: data breaches.

This year we’ve already seen quite a long list of data breaches from all around the world. While most of the focus usually falls on financial data breaches, many hackers are now going after softer targets, such as healthcare and social services. In fact, 2019 has already seen multiple data breaches related to the healthcare field.

In fact, 2019 has already seen multiple data breaches related to the healthcare field.

The number one danger of data breaches is identity theft. With just a few details, like your date of birth, social security number, etc., scammers can use your information to take out loans, get credit cards, or use it for more sophisticated phishing attempts.

Beyond that, they can also access the account that was hacked, collecting private messages, videos and images. In general, what hackers can do with your data is often limited to how creative they are. In order to keep yourself safe, you not only have to practice your own safety, but you need to be aware if your data is out there right now, in some hacker’s hands or being traded on hacker forums.
