Message: <blockquote data-quote="509322" data-source="post: 559848">A Smartscreen and UAC bypass can only happen if the malware is executed. The whole purpose of software restriction policies are to block the execution in the first place. For a file to execute the user launched it with either the SRPs disabled, the SRP configuration allows the launch, and\or there is a bug\vulnerability.  The most common scenario are the first two - with the last one a rarity.AppLocker if properly configured will block all high-risk file\process executions - even malicious *.lnk (shortcut) with arguments that download and drop files to writeable directories can be effectively handled.  Simply create policies that block the launch of executable files from writeable directories susceptible to malicious *.lnk attacks. Using an understanding of Windows and malware behaviors you can bolster AppLocker's basic configuration.</blockquote>
