It’s no secret how artificial intelligence (AI)-powered tools and systems, which promise users exponential productivity, growth, and efficiency, have quickly become integral in organizations' processes and workflows. AI — specifically generative AI (GenAI) and large language models (LLMs) — is now a foundational element of the software development process, allowing developers to build and scale software at a velocity that would have been impossible a mere decade ago. These technologies have permeated the software development lifecycle (SDLC), from ideation to maintaining software, ensuring that concepts are translated swiftly into code.

Vexed researcher Nightmare-Eclipse (aka Chaotic Eclipse, Dead Eclipse, and MSNightmare) released his ninth unpatched Windows vulnerability called LegacyHive. This latest bug drop is a Local Privilege Escalation (LPE) vulnerability affecting Windows User Profile, a component responsible for loading and unloading Windows user profiles. When exploited, LegacyHive can enable attackers to load other users’ hives and gain access to application data and Windows Explorer history, among others.
