QUOX and TINMAN show mixed health signals: QUOX has repeated SSH authentication failures and a failed systemd unit, while TINMAN reports high alert volumes and Python vulnerabilities.

Error significance: LLM reviewed 7 of 7 evidence groups. Interpretations use bounded samples; alert counts are not counts of confirmed incidents. Detector severity is unchanged.

Needs attention — TINMAN: CVE-2026-4519 affects Python 3.13.5 (64-bit) (7 Wazuh alerts in 24 hours). Scanner alerts identified CVE‑2026‑4519 affecting Python 3.13.5 (64‑bit) on the host. The vulnerability is present, but there is no evidence of exploitation or impact. Next: Verify whether Python 3.13.5 is actively used on the system and apply the appropriate patch or upgrade.

Needs investigation — TINMAN: Multiple Windows Logon Failures (114 Wazuh alerts in 24 hours). The host logged multiple Windows logon failures (event 4625) from public IPs, indicating repeated unsuccessful authentication attempts that could be a brute‑force effort. No successful logons are shown, so it is unclear whether the attempts were malicious or benign. Next: Review authentication logs for any successful logons originating from the same IP addresses.

Needs investigation — QUOX: security observations (9 observations in bounded collection). Multiple SSH authentication failures for the root account from external IPs were logged, which is typical of brute‑force attempts. No successful logins are recorded in the sample. Next: Examine the SSH logs for any successful authentication events from the same IP addresses to confirm whether the attempts succeeded.

Needs investigation — QUOX: Units currently retained in systemd failed state (1 units). The systemd unit snap‑cups‑1266.mount is in a failed state. This alone does not confirm a production outage; the unit may be obsolete or non‑critical. Next: Run `systemctl status snap-cups-1266.mount` to review the failure details and determine if the unit is required for current services.

Monitor — TINMAN: Multiple System error events (6 Wazuh alerts in 24 hours). DCOM communication failures were reported by Veeam Backup Manager when attempting to contact remote hosts. This suggests a connectivity or configuration issue that could affect backup operations. Next: Check the status and logs of the Veeam backup jobs to determine if backups are completing successfully.

Monitor — TINMAN: Multiple Windows error application events. (2 Wazuh alerts in 24 hours). Exchange Active Directory Topology service errors indicate that the service could not reach AD topology endpoints, potentially impacting mail routing or directory lookups. Next: Inspect the health of the Exchange services and verify that the AD topology endpoints are reachable and not blocked by a firewall.

Monitor — QUOX: lynis scanner review. The lynis scanner review is marked as stale, meaning the last scan may not reflect the current system state and could miss new vulnerabilities. Next: Execute a fresh lynis scan to obtain up‑to‑date security findings.

QUOX: uptime is 11d 3h 17m; load averages are 39.86279296875 / 38.3447265625 / 27.3037109375 across 56 CPUs. Memory use is 42.1% and swap use is 0.0%. Filesystems: / 74.7% used. During this reporting window QUOX recorded 0 important events: No important events in the reporting window. Security-log observations total 9 total (0 scanner items; 9 other security-log observations).

TINMAN: current Wazuh telemetry reports 4.2% CPU, 84.8% memory used, and volumes B: 75.9% used, C: 30.8% used, D: 43.6% used.

Wazuh: service state is HEALTHY; enrolled agents are TINMAN: active, QUOX: active. It recorded 129 level-10-or-higher alerts in the last 24 hours, attributed as TINMAN: 129.

QUOX backups: Local rsnapshot backup monitoring is disabled by configuration.

TINMAN backups: HEALTHY: The most recent scheduled TINMAN backup succeeded and the repository is reachable; last success 2026-10-29T05:17:48.7273840Z; schedule overdue false; no backup job is currently running; Backup Repository has 24.1% free.

Other follow-up: Resolve failed unit snap-cups-1266.mount: Review why snap-cups-1266.mount is still failed and decide whether it should be repaired, reinstalled, or disabled.; Review SSH authentication pressure: Investigate repeated authentication failures and confirm the current SSH exposure is acceptable.

Other recommendations: On QUOX, review SSH logs for successful root logins from the same IPs to determine if attempts were malicious.; On QUOX, run `systemctl status snap-cups-1266.mount` to assess whether this unit is required or can be disabled.; On TINMAN, investigate the source of 114 Windows logon failures and verify Python 3.13.5 usage for CVE-2026-4519.; Execute fresh lynis scans on both QUOX and TINMAN to ensure up-to-date security findings.
