# Dark Web Breach Sentinel — New Ransomware & Leak Alerts (`0xgollum/dark-web-breach-sentinel`) Actor

Watch a list of company names/domains and get alerted the moment one is disclosed as a ransomware or data-breach victim - built on the open ransomware.live threat-intel feed, with a per-client watchlist and alert-only-on-new-disclosure logic that generic breach lookup tools don't offer.

## Pricing

$250.00 / 1,000 breach alerts

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Dark Web Breach Sentinel — New Ransomware & Leak Alerts

Watch a list of company names/domains and get alerted the moment one is disclosed as a
ransomware or data-breach victim. Run on a schedule; only genuinely new disclosures since the
last check are reported, never the same one twice, and never the full history dumped as
"alerts" on the very first run.

### How it actually works (read before assuming this browses .onion sites itself)

This does **not** crawl Tor/.onion sites directly. It consumes the free public API of
[ransomware.live](https://www.ransomware.live) - an actively-maintained, respected open
threat-intel project that already does that crawling - and adds the part they don't offer:
a per-client watchlist with alert-only-on-new-disclosure logic. Verified live against the
real API (`api.ransomware.live/v2/recentvictims`) before shipping.

Checked against the closest Apify competitors before building (08/08/2026): "OnionSentinel"
and "Ransomware & Dark Web Data Breach Monitor" both exist, but both are on-demand
query/filter tools with no diffing over time - this is the one differentiated angle neither
of them covers.

### Input

- **Keywords** (required) — company names or domains to watch, e.g. `acme.com`, `Acme Corp`.
  Matched case-insensitively as a substring against the victim name, domain, and description.
- **Request timeout**.

### Output

One row per newly disclosed match: `watched_keyword`, `victim`, `domain`,
`ransomware_group`, `country`, `sector`, `attack_date`, `source_url`, `checked_at`.

### Known constraints

- Source feed only covers ransomware-gang leak-site disclosures, not every kind of breach
  (credential dumps, stealer logs, forum posts are out of scope for this version).
- First-ever run for a keyword establishes a silent baseline (no rows) rather than dumping
  historical matches as if they just happened - alerts start from the second run onward.

# Actor input Schema

## `keywords` (type: `array`):

Company names or domains to match against recently disclosed ransomware/breach victims. Run this on a schedule (daily) - each run compares against the last one and reports only newly disclosed matches.

## `request_timeout_secs` (type: `integer`):

HTTP request timeout for the feed check.

## Actor input object example

```json
{
  "keywords": [
    "acme.com",
    "Acme Corp"
  ],
  "request_timeout_secs": 20
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "keywords": [
        "acme.com",
        "Acme Corp"
    ]
};

// Run the Actor and wait for it to finish
const run = await client.actor("0xgollum/dark-web-breach-sentinel").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "keywords": [
        "acme.com",
        "Acme Corp",
    ] }

# Run the Actor and wait for it to finish
run = client.actor("0xgollum/dark-web-breach-sentinel").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "keywords": [
    "acme.com",
    "Acme Corp"
  ]
}' |
apify call 0xgollum/dark-web-breach-sentinel --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,0xgollum/dark-web-breach-sentinel"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
