Are we really enjoying life, thanks to technology, or are we more under stress? We don’t go online anymore, we are always online. Therefore, there are many areas where we need to pay more attention. The number of computers in our lives is constantly increasing: PCs, smartphones, tablets and “smart” devices such as TVs, music systems, thermostats and refrigerators that collect more and more data about us and our preferences. Many think “I have nothing to hide”. But this is a misconception. It’s amazing what can be made of even the most innocuous data. And who knows what information about us could suddenly be dangerous in 20 or 30 years?
In his analyses, Heimdall has repeatedly noticed short URL services in a particularly negative light in recent months. These URL shorteners generate an alternative, short URL that can be used on Twitter, for example. In this way, the number of characters used in a post can be reduced.

In this article, we will look back at a number of developments and show how Heimdall became increasingly active, especially in the second half of 2020.
The coronavirus is still an integral part of our everyday life. Contrary to the hopes of many people the threat situation will be existent after 2020. Financial hardship as well as restrictions on our everyday life, from the obligation to wear masks to the ban on accomodation to the death of cultural life will also shape the year 2021.
