In recent years, Application Whitelisting has been one of the new breeds of antimalware technology. However, malware has already developed techniques for dealing with and impeding this new technology’s adoption rate, from causing unwanted behavior in the solution to directly altering the execution of the security solution to avoid detection while making it appear as though it is operating correctly. This talk will demonstrate how malware can accomplish these negative outcomes by manipulating application certificates and using file system filter drivers. This talk will also discuss how to factor these vulnerabilities into your security decisions.
