threat intel error STIX indicator expired but still matched active alerts

Not specified by the original author.

TL;DR

Fix this in the threat intel matching job by acting on the exact message first: filter matched indicators by their expiration date at match time, retire the expired STIX indicator from the active set, rerun matching for the affected alerts, and confirm no alert still cites an indicator whose validity has ended. 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.

threat intel error STIX indicator expired but still matched active alerts

Use this when

• The operation in the threat intel matching job fails with this exact message: threat intel error STIX indicator expired but still matched active alerts.
• 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 the threat intel matching job, 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: filter matched indicators by their expiration date at match time, retire the expired STIX indicator from the active set, rerun matching for the affected alerts, and confirm no alert still cites an indicator whose validity has ended. 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 the threat intel matching job 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 threat intel matching job 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

Indicator stores keep expired indicators for history, and a matching job that does not check validity at match time keeps firing on intelligence the source itself has retired.

How to fix - threat intel error STIX indicator expired but still matched active alerts

The how-to phrasing for the same failure in the threat intel matching job. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: the threat intel matching job at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
