Number of EPT Hooks in One Page

Increasing the number of EPT hooks in one page

If HyperDng displays an error message stating that the maximum number of breakpoints in a single page is hit (e.g., "err, the maximum breakpoint for a single page is hit, you cannot apply more breakpoints in this page"), you can increase the number to avoid this error.

To fix this problem, you must build a customized version of HyperDbg that uses the most suitable number for your requirements.

Navigate to the source code and locate the following macro. In the header files, search for MaximumHiddenBreakpointsOnPage and you will see the following code:

/**
 * @brief Maximum number of hidden breakpoints in a page
 *
 */
#define MaximumHiddenBreakpointsOnPage 40

The above macro defines the default number of breakpoints that are possible to put on a single page (4096 bytes). You must increase it according to your estimation.

After that, rebuild HyperDbg, and use your custom-made version of the debugger.
