Briefing

GreenPlasma is analyst shorthand for a commodity kit observed in Q1 2026 that chains stolen interactive sessions with scheduled tasks running as NETWORK SERVICE and a legacy delegation on a maintenance account. This reconstruction contains no exploit code, only log shapes and timelines you would see in a ticket.

Your role

Incident commander reviewing outsourced MDR escalations.

Objective

Follow the simulated intrusion from helpdesk remote session to scheduled task to service-account abuse and domain-admin cleanup.
