## Summary

Addresses: elastic#166152 for `9.3.0`

Updates MITRE ATT&CK mappings to
[`v18.1`](https://attack.mitre.org/resources/updates/updates-october-2025/).
Last update was to `v17.1` in
elastic#231375.

To update,  I modified

https://github.com/elastic/kibana/blob/8da457eaa399310954edf4c98cfc0fb540ae48ad/x-pack/solutions/security/plugins/security_solution/scripts/extract_tactics_techniques_mitre.js#L22

to point to the `ATT&CK-v18.1` tag.

Then ran `yarn extract-mitre-attacks` from the root `security_solution`
plugin directory, and then `node scripts/i18n_check.js --fix` from
Kibana root to regen the i18n files.

## Acceptance Criteria

- [x] User can map and use new MITRE techniques in Security Solution
- [ ] The user-facing documentation is updated with the new version
- [ ] [MITRE ATT&CK®
coverage](https://www.elastic.co/guide/en/security/master/rules-coverage.html)
page
    - [ ] elastic/docs-content#4395

## Test Criteria

- [x] Verify that new techniques (see the changelog link above) are
available for mapping on the Rule Creation page under "Advanced
settings"
- [x] Verify that new techniques are available on the MITRE ATT&CK
coverage page
