Abstract
In recent years, governments worldwide have moved their services online to better serve their citizens. Benefits aside, this choice increases the danger of tracking via such sites. This is of great concern as governmental websites increasingly become the only interaction point with the government. In this paper, we investigate popular governmental websites across different countries and assess to what extent the visits to these sites are tracked by third-parties. Our results show that, unfortunately, tracking is a serious concern, as in some countries up to 90% of these websites create cookies of third-party trackers without any consent from users. Non-session cookies, that are created by trackers and can last for days or months, are widely present even in countries with strict user privacy laws. We also show that the above is a problem for official websites of international organizations and popular websites that inform the public about the COVID-19 pandemic.
