A computing system determines whether memory data pertaining to a block of dynamically allocated memory within an inferior process memory space satisfies one or more criteria in heuristics data. The computing system identifies a category to assign to the block of dynamically allocated memory based on the determination of whether the memory data satisfies the criteria and generates a reliability score for the block of dynamically allocated memory indicating a level of reliability of the identified category. The computing system categorizes the block of dynamically allocated memory based on a comparison of the reliability score and a previous reliability score of the block of the dynamically allocated memory.
