I got in - commenting seems disabled so I will post them here In general - having a hard time with the borderline between this object, and an intrusion set? The difference seems to be that, for Intrusion Set, we know who they are. For this one, we don't. If that is the main difference, why are there so many distinct top level properties? A Suspicious activity object allows individuals to group information together related to malicious activity, such as an incident, attempted incident or suspicious activity observed outside of their network. An Intrusion Set is a grouped set of adversarial behaviors and resources with common properties that is believed to be orchestrated by a single organization. An Intrusion Set may capture multiple Campaigns or other activities that are all tied together by shared attributes indicating a common known or unknown Threat Actor. RE outcome / suspicious-activity-outcome-ov - - Suggest the names just be "successful" and "unsuccessful", as "successful-compromise" assumes already the objective was compromise, which perhaps it was not. - Should "in progress" be an option? Or is that "unknown"? RE compromise-type / suspicious-activity-compromise-type-ov - - Shouldn't this same type of data be able to be used in Intrusion Set? Whats the difference between this and "goals" of intrusion set... seems fuzzy? I know we wanted to encode "destrictive" on Intrusion Set in the past somehow... RE observation-refs - Shouldn't these be sightings? This object is the epitome of a sighting is it not? - Jason Keirstead Lead Architect - IBM Security Cloud

cti-stix@lists.oasis-open.org> It seems I was sending these emails to the wrong distro, hopefully this works this time. Interested in everyone's thoughts Below is a link to the Suspicious Activity Object proposal. As requested I updated the object to use the embedded reference, similar to the Malware proposal rather than using a relationship. Comments welcome.
