For over a year our enSilo researchers have been looking into hooking engines and injection methods used by different vendors. It all started back in 2015 when we noticed injection issue in AVG but this was only the tip of the iceberg. A few months after that we noticed similar issues in McAfee and Kaspersky Anti-Virus. At that point we decided to extend our research and look into the security implications of hooking engines and injection techniques. The results were depressing.
