CoreKeygen is an app that may be downloaded from several software download sites. Its victims may have been looking to crack a certain software for Mac without paying money. However, this software may also pose as the identifier of activation keys for software you have purchased on your Mac. Either way, CoreKeygen may also show you tons of different ads.
The advertisements that are presented by this program remind us a lot of other adware we have recently seen, like HistoryCollector, WebApplookup and Glims.

- Banner adware.
- Pop-up ads.

These ads are risky mainly because seeing them could lead to some very problematic websites. Such websites could be the following types:
- Phishing pages.
- Scam sites.
- Virus websites.
- Fake Tech Support scams.

And this is not the only risk that this software could pose for your Mac. It could also use various types of trackers that can be utilized to obtain information directly from your web browser. Such trackers include cookies, tags, pixels and others and can be utilized to obtain different types of inforrmation, such as:
