摘要
Systems and methods for validating integrity of an executable file are described. In one aspect, multiple partial image hashes are generated, the combination of which represent a digest of an entire executable file. Subsequent to loading the executable file on a computing device, a request to page a portion of the executable file into memory for execution is intercepted. Responsive to intercepting the request, and prior to paging the portion into memory for execution, a validation hash of the portion is computed. The validation hash is compared to a partial hash of the multiple partial image hashes to determine code integrity of the portion. The partial hash represents a same code segment as the portion.
