Canary Files on Endpoints

What It Does

Distribute monitored files across the endpoint fleet to detect mass encryption and mass collection early.

Observable indicator. Mass file operations are detected within the first affected hosts.

Where It Sits

A technique is chosen from inside a form and emplaced on one layer. Both are the catalog’s own declarations; the position is counted in catalog order.

  • Form of maneuverM5 AmbushTrade space for information and time, and impose cost.
  • Terrain layerT2 DevicesThe entry fords. Key terrain: Mission-staff laptops, contractor devices, the server and VM fleet.
  • Position in the form5 of 13M5 carries 13 cataloged techniques; this is the 5th in catalog order.

Phases It Is Employed In

Employed in 2 of the campaign’s six phases. A phase named here means at least this technique is live in it — not that the form it belongs to is the main effort.

  • Phase IDeterVisible hardening, a deception grid, and a stated attribution posture.
  • Phase IISeize InitiativeDetect early, canalize movement, and buy decision time.

Controls That Assess It

The controls the catalog names against this technique. They are what an assessor would test to establish that it is emplaced and working — the indicator above is what shows it is working, which is a different question.

  • CE-2 Priority Intelligence RequirementsCycle Execution and Assurance — To direct analytic effort at named questions, so that collection and hunting answer what the accountable authority needs rather than processing what arrives.
  • TA-1 Decision Loop MeasurementTempo and Temporal Advantage — To make the defender's tempo a measured quantity rather than an impression, so that the numerator of temporal advantage exists at all.
  • SM-7 Deception EmplacementScheme of Maneuver — To obtain detection with no false-positive budget, and to ensure that signal is acted on rather than queued.

In MITRE D3FEND

What this technique is called in MITRE’s countermeasure ontology. The join runs technique-to-technique: D3FEND catalogs countermeasures, and the thing with a countermeasure’s shape here is the technique, not the control.

That a technique reaches a D3FEND countermeasure says the two describe the same defensive act. It does not say the countermeasure is deployed, configured, or working — that is an assessment finding about your estate, not a property of the framework.

Related Techniques

The catalog declares no relation for this entry, and no other entry names it — the inverse is derived here, so an incoming edge would show up even though this one never declared it. The techniques below share its assessment surface, which is the nearest adjacency the data supports.

Assessed Alongside

Not a declared relation: these are the techniques whose assessing controls overlap this one’s, ranked by how much of the two assessment surfaces coincide. Showing 6 of 35 that share at least one control.
