Wraith spent ten calls on a real unified alert and still lost the host: it took the UAM asset id for an agent id and the raw agent list ran past what a tool result carries. investigate_alert reads the alert, its detail, the host's agent (by id or UUID, then name), the other alerts and threats on that host around the detection, and the file SHA1's reputation, blocklist and fleet-wide threats, summarised in one answer. The operator sheet now starts with it (budget 8). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015RhL2gy6Sx6Y3FEsyBE3mZ

Anything SentinelOne can tell about an endpoint: the threat or alert behind
|
|
a SentinelOne alert (file, hashes, originating process and command line,
|
|
storyline, mitigation status, analyst notes), the agent's details and
|
|
network interfaces, the activity timeline, other threats on the same host
|
|
or for the same hash across the fleet, a SHA1's reputation, whether a hash
|
|
is blocklisted. Not for other vendors' alerts, and never for containment or
|
|
remediation (isolate, mitigate, scan): it only reads.
|
|
|
|
needs: |
|
|
The Riposte alert id, or a SentinelOne threat id / UAM alert id. For a
|
|
pivot without an alert: the computer name, a hash (SHA1 for reputation) or
|
|
a time window.
|
|
|
|
returns: |
|
|
Facts from SentinelOne, each with the command that produced it; "not found"
|
|
when a lookup came back empty; the exact call and error when one failed.
|
|
No verdict.
|
|
|
|
instructions: |
|
|
RULE ONE. investigate_alert does the investigation in ONE call: the alert,
|
|
the host, the other alerts and threats on the host, and the file's
|
|
reputation, blocklist and fleet-wide threats. Call it first, and do not
|
|
redo with other commands what it already answered.
|
|
|
|
1. get_incident_context (1 call). In its raw fields find the alert's id:
|
|
- a unified (UAM) alert: the "id" that is a UUID (8-4-4-4-12 hex,
|
|
e.g. 01a0f703-e969-7e53-80ba-870646032581). asset.id (a 26-letter
|
|
token) and agentUuid are NOT alert ids.
|
|
- a threat: threatInfo.threatId (a number of about 19 digits).
|
|
2. investigate_alert(alert_id=<the UUID>) or investigate_alert(
|
|
threat_id=<the number>) (1 call). Copy the id whole, character for
|
|
character. If it answers found: false, check the id once against the
|
|
raw fields and retry once; then report it.
|
|
3. Only for a question the answer leaves open (at most 4 calls):
|
|
- more of a hash: get_threats(query=<sha1 or file name>);
|
|
- the host's console timeline: get_activities(agent_ids=<host.agent_id
|
|
from the answer>);
|
|
- a UAM alert's full indicator list: get_unified_alert_details.
|
|
get_hash_verdict takes a SHA1 only (40 hex). Never a SHA256 or MD5.
|
|
|
|
Report, each fact with "investigate_alert" or the command that gave it:
|
|
- the alert: name, rule, severity, classification, status, verdict,
|
|
mitigation result, detection time, MITRE;
|
|
- the process: command line, parent, user, file, path, hashes, signer;
|
|
- the host: name, OS, IPs, last user, agent version, network status, site;
|
|
- elsewhere: its "window" word for word, the other alerts on the host by
|
|
name with their counts, the threats on the host, the file's reputation,
|
|
whether it is blocklisted, the threats carrying it across the fleet;
|
|
- each entry of "errors" as a check that could not be made, with its step.
|
|
Report what the answer says and nothing it does not: an empty or missing
|
|
section is "not found", never a guess. No verdict.
