# Unrecognized Snort Alert: ChatGPT-Assisted Recovery

English narration and permanently visible English captions accompany this recording of the October 31, 2026 Parser Studio Web UI. The examples come from published original manufacturer documentation or upstream-authored test fixtures, not from fabricated demo messages.

## Practice along with the video

Keep this page open to pause or replay the demonstration while working in a second tab.

**Before you begin:** [Download all practice samples as a ZIP](https://app.parser.xdr.ooo/training/parser-studio-current-20261031/practice/practice-all.zip) · [Open Parser Studio](https://app.parser.xdr.ooo/)

* [Download the original Snort alert](https://app.parser.xdr.ooo/training/parser-studio-real-scenarios-20261021/practice/03-snort-alert.log)
* [Download the two different holdout alerts](https://app.parser.xdr.ooo/training/parser-studio-real-scenarios-20261021/practice/03-snort-holdout.log)
* [Optional: download the reviewed educational JSON recipe](https://app.parser.xdr.ooo/training/parser-studio-real-scenarios-20261021/practice/03-snort-reviewed-recipe.json)

**Use the source files above exactly as shown in the video.** Each file contains the public documented sample events used during the recording, with source attribution and SHA-256 checksums in the ZIP bundle.

### Copy the exact logs used in the video

Use the **copy icon** on each code block, then paste the entire content into Parser Studio. Each line is one unmodified event from the published source. Do not omit difficult events or replace values to force a passing result.

#### Original Snort 3 alert\_fast event — paste this one line into Add Logs

**Exact source:** 225 bytes · **File:** `03-snort-alert.log` · Keep both lines when the file has two events.

```text theme={null}
07/16-09:23:39.153899 [**] [1:1000000:0] "SERVER-WEBAPP Apache Log4j arbitrary code execution attempt" [**] [Classification: Attempted User Privilege Gain] [Priority: 1] [AppID: HTTP] {TCP} 192.168.1.2:50284 -> 192.168.2.3:80
```

#### Two independent Snort alerts — paste these ONLY into Additional test logs

**Exact source:** 342 bytes · **File:** `03-snort-holdout.log` · Keep both lines when the file has two events.

```text theme={null}
07/16-09:23:39.153899 [would_drop] [**] [1:1000000:0] "SERVER-WEBAPP Apache Log4j arbitrary code execution attempt" [**] [Classification: Attempted User Privilege Gain] [Priority: 1] {TCP} 192.168.1.2:50284 -> 192.168.2.3:80

```

#### Optional: the reviewed demonstration ParserRecipe JSON

This JSON is an **educational proposal, not an automatically trusted AI answer**. Analyze the one original event first, test this proposal with two independent alerts, and approve the tested change explicitly.

Download the same reviewed JSON: [03-snort-reviewed-recipe.json](https://app.parser.xdr.ooo/training/parser-studio-real-scenarios-20261021/practice/03-snort-reviewed-recipe.json).

### Follow the current on-screen steps

1. Open **Auto Parser**, enter manufacturer **Snort** and product **Snort 3**, then paste only the one original alert.
2. Click **Analyze Logs** and inspect the **0 of 1 log event parsed completely** result. Preserve the whole alert and its unparsed regions.
3. Use **Fix with ChatGPT** and inspect the generated source-bearing prompt. **Prepare ChatGPT Prompt**, then **Copy Prompt** only after confirming that external sharing is allowed.
4. The new recording ends at the prompt-review stage; it does **not** pretend an external ChatGPT result was returned. To continue yourself, paste the model response into **ChatGPT result JSON** and select **Check ChatGPT Result**.
5. For a reviewable proposal, add the two independent holdout alerts under **Different examples to test the fix** and check **Confirm test examples are different**. Test before applying or downloading. The optional recipe displayed above is educational, not automatically trusted.

## Expected review outcome

The original Snort alert\_fast sample is not fully parsed at first. The updated video demonstrates the actual prompt preparation and privacy boundary; an external ChatGPT answer and independent holdout validation remain separate user steps.

Do not treat successful source extraction or generated files as evidence of full vendor/firmware coverage, target import acceptance, or live Stellar Cyber deployment compatibility.

## Recovery path

For a different log shape, keep the original records and examine the highlighted source spans, following the [related workflow](https://parser.xdr.ooo/scenarios/unknown-log.md). Only apply additional parsing rules after different examples pass a separate regression test. Never delete failing events merely to obtain a passing total.

> Customer logs may include private information. Review, sanitize and manually approve any excerpt before copying it into an external ChatGPT conversation. The Auto Parser does not automatically share those logs.
