SOC agent broke parsing MISP STIX bundle indicators imported without sightings

TL;DR

Fix this in the SOC agent parsing a MISP STIX bundle by acting on the exact message first: parse the STIX bundle object by object, keeping indicators and their sightings linked by their shared references, validate the imported count of sightings against the bundle, and reimport the bundle if sightings were dropped. 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.

Use this when

• The operation in the SOC agent parsing a MISP STIX bundle fails with this exact message: SOC agent broke parsing MISP STIX bundle indicators imported without sightings.
• 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 SOC agent parsing a MISP STIX bundle, 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: parse the STIX bundle object by object, keeping indicators and their sightings linked by their shared references, validate the imported count of sightings against the bundle, and reimport the bundle if sightings were dropped. 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 SOC agent parsing a MISP STIX bundle 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 SOC agent parsing a MISP STIX bundle 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

A bundle parser that imports only indicator objects and ignores relationship and sighting objects produces indicators with no evidence of observation, which changes how analysts weigh them.

The how-to phrasing for the same failure in the SOC agent parsing a MISP STIX bundle. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Compatibility: the SOC agent parsing a MISP STIX bundle 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.
