External Denial of Service

The subject initiates or facilitates a denial of service attack targeting public-facing organizational services, such as corporate websites, client portals, or externally accessible APIs, through external means.

In some cases, the subject may coordinate with external actors to mask attribution, prolong disruption, or cause reputational damage.
