A detection is an aggregated view of a single attacker session observed on one of your deployed sensors: the commands that ran, the MITRE… - [Get Tactics Detection](https://docs.greynoise.io/reference/gettacticsdetection.md): Retrieve a single Tactics detection, including its complete ordered command timeline, its full set of touched file paths, and a per-protocol summary of the unique destination IPs the session… - [List Tactics Detection Destination IPs](https://docs.greynoise.io/reference/listtacticsdetectiondestinationips.md): List the unique remote IP addresses a detection's session contacted, sorted for stable pagination. Internet-routable addresses are returned by default; this includes link-local (cloud instance… - [List Tactics Detection Files](https://docs.greynoise.io/reference/listtacticsdetectionfiles.md): List the files observed during a detection's session, with each file's path, size, type, and hashes. Set `mutations_only=true` to restrict the response to files the session actually created or… - [Get Host Artifact Content](https://docs.greynoise.io/reference/gettacticshostartifactcontent.md): Fetch the contents of a single file observed on one of your deployed sensors, identified by its path within the workspace. The most recently observed version of the file at that path is returned.… - Psychic - [Psychic Model Download](https://docs.greynoise.io/reference/postpsychicmodeldownload.md): Downloads a Psychic model file. The request body selects the model (`1`, `2`, `3`, `m1`, `m2`, `m3`, `model1`, `model2`, or `model3`). Models 1, 2, and 3 may set `date` to `latest` or a `YYYY-MM-DD`… - [Psychic Snapshot Download](https://docs.greynoise.io/reference/postpsychicsnapshotdownload.md): Downloads a precomputed Psychic snapshot artifact. Snapshots are fixed, already-materialized files for common rolling windows. This endpoint does not generate missing ranges or convert missing MMDBs.… - Callback - [Callback IP Lookup](https://docs.greynoise.io/reference/callbackgetip.md): Retrieve detailed information about a specific callback IP, including attack stage, scanner associations, and downloaded malware files. - [List Callback IPs](https://docs.greynoise.io/reference/callbacklistips.md): Retrieve a paginated list of callback IPs with filtering by attack stage, date ranges, file attributes, and scanner associations. - [Export Callback IPs](https://docs.greynoise.io/reference/callbackexportips.md): Export callback IPs matching the given filters as a newline-delimited plain text list. Supports the same filter parameters as the List Callback IPs endpoint. - [Callback Overview Statistics](https://docs.greynoise.io/reference/callbackoverview.md): Retrieve aggregate statistics for callback IPs including counts by attack stage, file analysis status, scanner associations, and top threat names. ## Pages - [Product Roadmap](https://docs.greynoise.io/page/testing.md)
