Summary

Hide ▲

Microsoft has restricted the use of Internet Explorer (IE) mode in its Edge browser after threat actors exploited it to gain unauthorized access to users' devices. The attackers used social engineering and unpatched exploits in IE's JavaScript engine (Chakra) to achieve remote code execution and privilege escalation. The attack involved tricking users into reloading a page in IE mode, allowing the attackers to bypass modern browser defenses and perform various post-exploitation activities. Microsoft has removed the dedicated toolbar button, context menu, and hamburger menu items for IE mode, requiring users to enable it explicitly for specific sites.
