'Cup' Browser Extension

'Cup' Browser Extension Description

The 'Cup' browser extension is essentially an annoying PUP (Potential Unwanted Program) that could perform various intrusive actions on the systems it is installed on. The application could display adware and browser hijacker capabilities. Users should avoid allowing such applications onto their computers or devices by inspecting carefully any software bundles or installers coming from unproven sources.

When activated, the 'Cup' browser extension could begin generating numerous, unwanted advertisements. The advertisements may be displayed as pop-ups, banners, in-text links, and more. In addition, these advertisements are likely to promote questionable or even unsafe sites or software products. Users may see advertisements for fake giveaways, technical support or phishing sites, suspicious betting/gaming platforms, etc. Other side effects of having 'Cup' installed, may include unwanted redirects to other similarly dubious destinations.

It is important to keep in mind that PUPs are notorious for carrying data-tracking capabilities. Chances are that these applications will try to monitor the user's browsing activities, while also collecting numerous device details. However, some PUPs also have been observed attempting to access sensitive information contained in browsers' autofill data. Usually, this is where the browser will keep information that users want to be automatically populated on websites, such as usernames, passwords, payment details, etc.
