### Trusted vendor binary / installer launching unusual children

`UC_SUPPLY_CHAIN` · phase: **exploit** · confidence: **Medium**

**Splunk SPL (CIM):**
```spl

    from datamodel=Endpoint.Processes
    where Processes.parent_process_name IN ("setup.exe","installer.exe","update.exe")

    by Processes.dest, Processes.user, Processes.parent_process_name, Processes.process_name, Processes.process

### 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.

- **Network connections to article IPs / domains** ([template](../_TEMPLATES.md#network-ioc)) — phase: **c2**, confidence: **High**
  - IP / domain IOC(s): `192.236.147.131`, `192.236.147.138`, `193.141.60.212`, `192.236.154.158`, `192.236.146.173`, `174.169.162.62`, `64.94.84.97`, `business-data-leaks.com`


## Why this matters

Severity classified as **CRIT** based on: IOCs present, 18 use case(s) fired, 27 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.
