Flash cookies are small data files that Adobe Flash Player embeds into a user’s computer to track and monitor users’ online activity across the internet. They work similarly to traditional cookies by customizing the users’ experience, but they have a significantly larger data storage capacity. Moreover, they keep track of sensitive data, such as login credentials, browsing history, and user preferences. Due to this, people see them as potential trackers. Flash cookies also recreate browser cookies users might delete, which increases the difficulty of getting rid of them. Additionally, a web browser doesn’t manage them. Thus, users are not even aware that flash cookies track their activity and may need to be removed. Hackers take advantage of the user data records that flash cookies keep.
