## Recommended hunts

### Joomla JCE profile.import unauthenticated RCE attempt (CVE-2026-48907)

`UC_10_2` · phase: **exploit** · confidence: **High** · AI-generated for this article

**Splunk SPL (CIM):**
```spl
| tstats `summariesonly` count min(_time) as firstTime max(_time) as lastTime values(Web.url) as url values(Web.src) as src values(Web.status) as status from datamodel=Web.Web where Web.url="*com_jce*" AND (Web.url="*task=plugin*" OR Web.url="*profile*" OR Web.url="*imgmanager*" OR Web.url="*filemanager*") by Web.dest Web.http_method Web.user_agent | `drop_dm_object_name(Web)` | where status<400 OR status=200 | `security_content_ctime(firstTime)`
```

**Defender KQL:**
```kql
DeviceNetworkEvents
| where Timestamp > ago(7d)
| where LocalPort in (80, 443, 8080, 8443)
| where RemoteIPType == "Public"
| where InitiatingProcessFileName in~ ("w3wp.exe","httpd.exe","apache2","nginx","php-fpm")
| where RemoteUrl has_any ("com_jce","index.php?option=com_jce","task=plugin","imgmanager","filemanager")
   or AdditionalFields has_any ("com_jce","profile.import")
| project Timestamp, DeviceName, RemoteIP, RemoteUrl, LocalPort, InitiatingProcessFileName, InitiatingProcessCommandLine
| order by Timestamp desc

### IOC-driven hunts (use shared templates)

These are standard IOC-substitution hunts — the canonical SPL and KQL live once in [`_TEMPLATES.md`](../_TEMPLATES.md), so we don't repeat the same boilerplate on every CVE / hash / network-IOC briefing.

- **Asset exposure — vulnerability matches article CVE(s)** ([template](../_TEMPLATES.md#asset-exposure)) — phase: **recon**, confidence: **High**
  - CVE(s): `CVE-2026-48907`

- **Network connections to article IPs / domains** ([template](../_TEMPLATES.md#network-ioc)) — phase: **c2**, confidence: **High**
  - IP / domain IOC(s): `107.149.130.5`, `92.38.150.143`, `45.153.129.241`


## Why this matters

Severity classified as **HIGH** based on: CVE present, IOCs present, 4 use case(s) fired, 4 technique(s) inferred. Read the full article for actor attribution, tooling details, and any defanged IOCs in the body that aren't visible in the RSS summary.
