Cloystercdn.com is a bogus website designed to redirect its visitors to other untrusty websites or deliver potentially unsafe content to their computers. Usually, people come across this online tactic because they have a browser hijacker installed within their browser, redirecting them to such questionable pages. Cloystercdn.com first checks its visitors' IP addresses to determine their geolocation; then, it decides which actions to perform.

Cloystercdn.com also uses a well-known trick to make users subscribe to its browser notifications. Cloystercdn.com displays a fake error message with an embedded 'Allow" button and then asks the visitor to click on that button to proceed to the website's actual content. Users who agree to receive messages from Cloystercdn.com will only be flooded with intrusive advertisements appearing all the time on top of any other content and containing links to other unsafe websites where the user's computer can get infected with additional Potentially Unwanted Programs (PUP) stealthily. PUPs should be removed from the device immediately, as they often have data-collection features and can, thus, cause serious privacy issues.
