ClickDark, as its name suggests, is a browser extension advertised as a convenient way for users to switch websites into the Dark Mode, even if the pages do not support such functionality on their own. Extensions offering such features have become rather popular, but users must be careful when installing anything they are not familiar with. Indeed, infosec experts warn that ClickDark has adware capabilities that are not sufficiently presented to users prior to the installation of the program.

Adware applications are designed to generate monetary gains for their operators through the delivery of intrusive and unwanted advertisements. Users risk having their devices flooded by advertisements that could potentially be promoting fake giveaways, technical support or phishing tactics, shady adult-oriented sites, online betting/gaming platforms and more. Interacting with the shown advertisements also could trigger redirects to similarly untrustworthy destinations. 

At the same time, many adware, browser hijackers, and PUPs (Potentially Unwanted Programs) will perform additional intrusive actions in the background of the system. In most cases, these applications will try to collect browsing information (search history, browsing history and clicked URLs) and device details (IP address, geolocation, browser type, device types, etc.) However, some dubious applications also try to access sensitive information contained in browsers' autofill data. This could lead to users having certain account credentials, banking details, credit/debit card numbers and other vital information compromised.
