Once upon a time, I started at TASZK Security Labs as an intern. My internship project was about hacking hypervisors, and the target we picked for it was Huawei’s HEE (Hypervisor Execution Environment). The research was carried out in late 2020 to early 2021. Although we didn’t publish this work all the way until 2025, it was kept relevant by the fact that the issues remained unaddressed, to the best of our knowledge. If that piqued your interest in the story of the disclosure, please check out our recent Troopers/LeHack talk titled Eastern Promises. In this blogpost, I’ll focus on the technical aspects of the project.
