We will explore how we could use COM hijacking and this custom communication to gain SYSTEM privileges (CVE-2023-6154). Additionally, we will examine how to mitigate the vulnerabilities discussed throughout this series of blog posts. Lastly, we will demonstrate how COM hijacking can be exploited to perform a Denial-of-Service (DoS) attack on security products. Author: Alain Rödel and Kolja Grassmann
