Abstract
A technique for detecting malware uses hardware capabilities of the processing element of a programmable device to detect modification of executable code during execution. By monitoring a dirty bit in page tables, pages that have been modified can be detected, allowing analysis of those pages during execution. An indication may then be passed to an anti-malware software to analyze the executable further.
