SentinelOne‘s patent involves protecting DLL hooks by mapping new executable addresses to former executable samples. Attempts to read or write are controlled, debuggers are detected, and a kernel component denies debugging privileges. The method redirects native DLL functions to a security DLL for threat mitigation. GlobalData’s report on SentinelOne gives a 360-degree view of the company including its patenting strategy.

Protecting dll hooks from unauthorized access and modification
A recently granted patent (Publication Number: US11899782B1) discloses a method and system for enhancing security measures in computer systems. The method involves modifying memory to include a reference to a security dynamic link library (DLL) to redirect the invocation of functions associated with a native DLL to the security DLL, which performs threat mitigation functions. The system restricts access to specific memory addresses by sources based on a mapping entry, limiting debugging privileges to enhance security measures. The method also includes detecting and managing debugging executables to ensure the system's integrity.
Furthermore, the system described in the patent includes one or more processing devices and memory devices that store executable code to implement the security measures. By modifying memory to include references to security DLLs and restricting access to memory addresses based on mappings, the system effectively enhances security by preventing unauthorized access to critical system components. Additionally, the system's ability to detect and manage debugging executables adds an extra layer of protection against potential security threats. Overall, the patent provides a comprehensive approach to improving security measures in computer systems through innovative methods and system configurations.
