  • →Monitor for mousedown events invoking the Popup.show method in Internet Explorer, which may indicate exploitation of HijackClick 3 / Script in Image Tag File Download Vulnerability ↗
  • →Watch for use of the shell: URI scheme (e.g., shell:favorites\) in browser-context location assignments, which is a technique used in the method-caching variant of this attack to drop or execute files ↗
  • →Detect drag-and-drop interactions originating from popup windows spawned by Popup.show in Internet Explorer 6.x, as this is the core mechanism for hijacking user mouse events to approve dialogs or trigger downloads ↗
  • ·The method-caching variant of this attack is also reported to work, meaning detection rules targeting only the direct Popup.show call may miss alternate exploitation paths ↗
  • ·Affected scope includes Internet Explorer 5.0.1 in addition to IE 6.x; detections should not be scoped exclusively to IE 6 ↗
