The Blacole family is designed to load a hidden IFrame that contacts a malicious page that is stored on a web server. This page determines information about your browser, such as what browser it is (for example, Internet Explorer or Firefox), what version it is, and what plugins or extensions you have installed.
The page then redirects the hidden IFrame to another page (or multiple pages) that specifically uses or exploits only those vulnerabilities that your browser is susceptible to. These vulnerabilities are then used to download malware onto your computer.
In this way, Blacole forms part of a larger process, all of which is designed to have the greatest success of infecting your computer with malware.
For more details, see the BlacoleRef and Blacole family descriptions.
