Security readout for executives and security teams

This is a legacy browser risk: a Dart Communications PowerTCP ZIP ActiveX control can overflow memory in Internet Explorer 6 and allow code execution when a user is lured into interacting with malicious content. The provided sources do not show current active exploitation or a named patch. Exposure is most likely in very old Windows environments that still allow IE6 and legacy ActiveX controls, especially where line-of-business applications installed Dart PowerTCP ZIP components. Modern managed browsers are unlikely to load this control by default. Treat this as a legacy-technology cleanup issue with high impact if present. Prioritize discovery and removal in regulated, kiosk, manufacturing, or long-lived Windows environments before spending effort on modern desktop fleets. Mitigation focus: Inventory systems for DartZip.dll 1.8.5.3 and dependent applications.; Remove the PowerTCP ZIP ActiveX control where it is not required.; Block unapproved ActiveX controls in legacy Internet Explorer environments..
