scoping-an-incident-from-a-single-indicator

Expands one indicator into the full scope of an incident: pivoting across data sources to find related hosts, accounts, and infrastructure, building a timeline, and bounding what is and is not affected. Activates for requests to scope an incident, pivot from a single IOC, or determine the blast radius of a detection.

Scoping an Incident from a Single Indicator

When to Use

  • A detection fired on one indicator (a hash, IP, domain, or account) and you must find the full extent of the activity.
  • You need to bound the incident — which hosts, accounts, and infrastructure are involved — before containment.
  • You are building an investigative timeline from a single starting point.

Do not use premature containment on the first indicator alone — acting before scoping can tip off the adversary and leave footholds you have not yet found.

Prerequisites

  • Access to relevant data sources (EDR, proxy, DNS, auth logs) and the pivoting/enrichment skills.

Workflow

Step 1: Characterize the seed indicator

Establish what the indicator is, when it was first/last seen, and on which host/account it appeared.

Step 2: Pivot to related artifacts

Expand outward: the file's other hosts, the IP's other connections, the account's other logons, the domain's other resolvers. Each pivot yields new indicators to pivot again.

python scripts/analyst.py scope events.json --seed <sha256-or-ip>

Step 3: Build the timeline

Order all discovered events chronologically to reconstruct the activity and find the earliest sign (candidate patient zero / initial access).

Step 4: Bound the scope

Define affected vs. unaffected explicitly: list involved hosts/accounts/infrastructure and the evidence for inclusion, and note what was checked and cleared.

Step 5: Hand off to containment

Produce the scoped picture (entities, timeline, indicators) so containment is coordinated and complete rather than piecemeal.

Validation

  • Every included entity has explicit evidence tying it to the incident.
  • The timeline has a defensible earliest event (initial access candidate).
  • Cleared entities are documented, so scope is bounded, not open-ended.

Pitfalls

  • Containing the first host before pivoting, alerting the adversary and missing other footholds.
  • Pivoting only one hop and missing second-order related entities.
  • No timeline, so initial access and dwell time stay unknown.
