Security analyst Tushar Karumudi is applying advertising technology data to threat intelligence investigations through paytrace, an open-source project that follows shared advertising identifiers across websites. When a suspicious or anonymous domain reveals little about its operator, connected sites may contain useful ownership clues in current or archived pages. By combining advertising IDs with resources such as the Wayback Machine and OpenCorporates, investigators can develop leads about the people or businesses behind websites. The findings still require verification, but the approach gives analysts another way to investigate suspicious domains.
