A malicious extension could therefore upload all your important files under My Documents to a malicious server, for example. Protected mode does however give read access to the entire file system. An extension can write to the registry only under HKEY_CURRENT_USER\Software\AppDataLow\Software. Write access to the registry is also limited. An extension can therefore only launch an application with a low integrity, which means that it will have limited system access. Windows applications have a medium integrity, which means that Internet Explorer cannot run any application without an explicit permission from the user (UAC popup). Zscaler Safe Shopping for Internet Explorer for example, creates a sub-directory in LocalLow to store the list of fake stores.Įxtensions can run executables that have a low integrity only. Any untrusted application can write to LocalLow without triggering any User Account Control ( UAC) violations, including applications deployed with ClickOnce. Internet Explorer extensions have write access to /AppData/LocalLow and a few folders useed by Internet Explorer to store cookies and favorites. This means that they have limited access to the system: read/write access to the file system, the registry and limited ability to run executables.
Protected Mode enabled by default in IE 9īefore I talk to the changes made in Windows 8, let me explain what Protected Mode does in Internet Explorer versions 7 through 9, especially when it comes to browser extensions. Internet Explorer, along with any extensions and plugins, run with a low integrity. Protected Mode aims to keep users safe by restricting what BHOs (Browser Helper Objects, aka browser extensions) and plugins can do inside Internet Explorer. With Windows 8, Microsoft added Enhanced Protected Mode. Microsoft Introduced Protected Mode in Internet Explorer with Windows Vista in 2006.
