Not specified by the original author.

TL;DR

Fix this in CrowdStrike Falcon by acting on the exact message first: resolve the device in CrowdStrike Falcon by its sensor identifier and last seen hostname rather than the stale device record in the incident, confirm the current device status, and write the containment status from that live device record back to the incident. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

CrowdStrike Falcon error "device not found" containment status missing from incident

Use this when

• The operation in CrowdStrike Falcon fails with this exact message: CrowdStrike Falcon error "device not found" containment status missing from incident.
• The same failure repeats on retry with unchanged inputs.
• An alert, incident or enrichment step is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in CrowdStrike Falcon, and copy the full message plus the alert, incident or enrichment record involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: resolve the device in CrowdStrike Falcon by its sensor identifier and last seen hostname rather than the stale device record in the incident, confirm the current device status, and write the containment status from that live device record back to the incident. Verify: the single failing item now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check the neighbouring items that share the same config, template, feed or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in CrowdStrike Falcon so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in CrowdStrike Falcon on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

Devices that were reimaged or re enrolled get a new device record, so an incident holding the old record reports the device as not found even though the endpoint is online under its new record.

TL;DR

Fix this in osquery fleet evidence by acting on the exact problem first: check the osquery enrolment and scheduled query packs for the Windows platform, confirm the snapshot query includes Windows hosts rather than only other platforms, re-enrol one missing host as a test, and rerun the snapshot counting hosts by platform. Do not rerun the whole job or collection unchanged, because the same inputs produce the same failure. Prove the fix on one control, account or batch first, then rerun the full scope and reconcile the counts.

Windows hosts missing from device compliance snapshot

Use this when

• The operation in osquery fleet evidence fails with this exact message or symptom: Windows hosts missing from device compliance snapshot.
• The same failure repeats on retry with unchanged inputs.
• An audit, evidence package or compliance review is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with an auditor judgment or a control design choice. That is a review discussion, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in osquery fleet evidence, and copy the full message plus the control, account or item involved into the run notes. Verify: the problem is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this problem: check the osquery enrolment and scheduled query packs for the Windows platform, confirm the snapshot query includes Windows hosts rather than only other platforms, re-enrol one missing host as a test, and rerun the snapshot counting hosts by platform. Verify: the smallest failing scope now completes, or the named control, account or item behaves as the fix predicts.
3. Check the neighbouring controls, accounts or items that share the same connection, mapping or owner, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in osquery fleet evidence on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts or status against the source in osquery fleet evidence so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

Why it happens

Fleet queries are often written and tested on one platform, so a platform filter or a missing Windows pack leaves those hosts enrolled but never reported.

Edge cases

• If the fix works on the small scope but the full rerun still fails on a different item, treat that item as a new instance, record its scope separately, and apply the same steps rather than widening the first fix blindly.
• If evidence was already sent to an auditor in the wrong state, correct the record with a dated note explaining what changed, rather than silently replacing files in the package.
• If two settings or mappings could both produce this symptom, change one at a time and retest the small scope after each change, so the working fix is known rather than guessed.

Compatibility: osquery fleet evidence at current versions, plus the admin console or API the query names; no extra tooling beyond the source system access needed to verify counts.

Fix this in the CrowdStrike webhook intake by acting on the exact message first: compare the signing value in the intake config with the current value in the CrowdStrike console after any rotation, update the config, and verify the proxy in front of intake forwards the raw request body unchanged for signature checking. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

CrowdStrike alert webhook failed error signature verification failure SOC intake

Use this when

• The operation in the CrowdStrike webhook intake fails with this exact message: CrowdStrike alert webhook failed error signature verification failure SOC intake.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the CrowdStrike webhook intake, and copy the full message plus the alert, incident or enrichment record involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: compare the signing value in the intake config with the current value in the CrowdStrike console after any rotation, update the config, and verify the proxy in front of intake forwards the raw request body unchanged for signature checking. Verify: a test event from the console passes signature verification and creates an intake record.
3. Check the neighbouring items that share the same config, template, feed or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in the CrowdStrike webhook intake so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the CrowdStrike webhook intake on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

signature checking runs over the exact bytes sent, so a rotated signing value or a proxy that re-serializes the body makes valid events fail verification.
