After social engineering produced account takeover of a finance clerk, the actor used the mailbox for email compromise. Splunk now shows large uploads of tax-roll files to an external host. Which blueprint term names the current stage?

Defense Analyst objective 2.2 expects the term that matches current attacker behavior, not the first successful stage. Social engineering and account takeover explain how the clerk identity was seized, and email compromise explains mailbox abuse, but large outbound copies of tax-roll files are exfiltration. Zero trust is a defensive model and does not name the theft. Civic analysts should disposition and hunt the current stage in web, proxy, and DLP data while still recording the earlier chain in the investigation.
