## Subcategories

## Investigation Workflow

1. **Define search terms**: Identify item descriptions, serial numbers, unique identifiers
2. **Broad sweep**: Use Search Tempest or SearchAllJunk for cross-platform coverage
3. **Craigslist deep search**: Use TotalCraigSearch for nationwide Craigslist coverage
4. **eBay investigation**: Search active and completed listings; use Goofbid for misspelled items
5. **Local marketplaces**: Check OfferUp for local sellers; note seller profiles and locations
6. **International reach**: Search Kijiji (Canada), Quikr (India), Kleinanzeigen (Germany) as needed
7. **Seller profiling**: Note usernames, phone numbers, email addresses from listings
8. **Cross-reference**: Pivot to `people-search` for seller identity, `phone-recon` for phone numbers

## Web Investigation Procedures

### Google Dork -- Craigslist Nationwide Search

```
site:craigslist.org "serial number" OR "model number" "item description"
```

### Google Dork -- eBay Sold Items

```
site:ebay.com "sold" "item description" "serial number"
```

### Google Dork -- OfferUp Seller Search

```
site:offerup.com "seller username" OR "phone number"
```

### eBay Advanced Search (Completed Listings)

Navigate to `https://www.ebay.com/sch/ebayadvsearch` and enable
"Completed listings" and "Sold items" filters to see historical
sale prices and seller activity.

### Craigslist RSS Feed Monitoring

```
https://CITY.craigslist.org/search/sss?query=SEARCH_TERM&format=rss
```

Replace CITY with the target city subdomain and SEARCH_TERM with
URL-encoded search keywords. Subscribe to this RSS feed for
automated monitoring of new listings.

### cURL -- Craigslist Search via RSS

```bash
curl -s "https://newyork.craigslist.org/search/sss?query=macbook+pro&format=rss" \
| grep -oP '<title>\K[^<]+' |
```

### cURL -- eBay Browse API (requires OAuth)

```bash
curl -s "https://api.ebay.com/buy/browse/v1/item_summary/search?q=vintage+watch&limit=5" \
  -H "Authorization: Bearer $TOKEN" \
  -H "X-EBAY-C-MARKETPLACE-ID: EBAY_US" \
| jq '.itemSummaries[] |
```

### Monitoring Pattern -- Repeat Search with Diff

```bash
# Save baseline, then diff for new listings
curl -s "https://newyork.craigslist.org/search/sss?query=stolen+bike&format=rss" > /tmp/cl_baseline.xml
# ... wait interval ...
curl -s "https://newyork.craigslist.org/search/sss?query=stolen+bike&format=rss" > /tmp/cl_current.xml
diff /tmp/cl_baseline.xml /tmp/cl_current.xml
```

## Cross-Category Pivots

| When you find... | Pivot to | Why |
| ------------------ | ---------- | ----- |
| Seller phone number | `phone-recon` | Carrier lookup, caller ID, linked accounts |
| Seller email address | `email-recon` | Email verification, breach data, linked profiles |
| Seller username | `username-recon` | Cross-platform profile discovery |
| Item photos in listings | `images-videos` | Reverse image search, EXIF metadata extraction |
| Seller location / address | `people-search` | Identity verification, address history |
| Vehicle listing with VIN | `transportation` | VIN decode, theft database check |

## OPSEC Notes

- All classified tools listed are **passive** web searches -- no target notification
- Craigslist blocks aggressive scraping; use RSS feeds for monitoring
- eBay tracks search activity when logged in; use private browsing for anonymity
- OfferUp requires the app for full functionality; web access is limited
- Seller phone numbers on classifieds may be VoIP or burner numbers
- Do not contact sellers as part of investigation without legal authorization
- Screenshots of listings should be captured promptly as classified ads are frequently deleted
- Craigslist does not retain deleted postings; archive immediately with `archives-cache` tools
- Image metadata (EXIF) in listing photos may reveal location and device information
