Overall, the trends of the last few months were maintained in September. Web malware bundles designed to exploit the myriad vulnerabilities found in major products are still increasing in number, giving cybercriminals plenty of opportunities for malicious activity. Simple iframe-clickers placed on legitimate, but infected sites, help spread these bundles. And cybercriminals are able to access these legitimate sites and place malware on them because they have previously used other malware designed to steal confidential data such as passwords. These steps all make up a cyclical process of compromise and infection which can be endlessly repeated.
