# Elasticsearch Recon Ingestion Scripts (ERIS)
|
|
> A utility for ingesting various large scale reconnaissance data logs into Elasticsearch
|
|
|
|
The is a suite of tools to aid in the ingestion of recon data from various sources *(httpx, masscan, zonefiles, etc)* into an [Elasticsearch](https://www.elastic.co/elasticsearch) cluster. The entire codebase is designed with asynconous processing, aswell as load balancing ingestion across all of the nodes in your cluster. Additionally, live data ingestion is supported from many of the sources supported. This means data can be directly processed and ingested into your Elasticsearch cluster instantly. The structure allows for the developement of "modules" or "plugins" if you will, to quickly create custom ingestion helpers for anything!
|
|
|
|
## Prerequisites
|
|
- [python](https://www.python.org/)
|
|
- [elasticsearch](https://pypi.org/project/elasticsearch/) *(`pip install elasticsearch`)*
|
|
- [aiofiles](https://pypi.org/project/aiofiles) *(`pip install aiofiles`)*
|
|
- [aiohttp](https://pypi.org/projects/aiohttp) *(`pip install aiohttp`)*
|
|
- [websockets](https://pypi.org/project/websockets/) *(`pip install websockets`) (only required for `--certs` ingestion)*
|
|
|
|
## Usage
|
|
```shell
|
|
python eris.py [options] <input>
|
|
```
|
|
**Note:** The `<input>` can be a file or a directory of files, depending on the ingestion script.

|
|
| `--httpx` | Index HTTPX records |
|

|
|
|
|
~~This ingestion suite will use the built in node sniffer, so by connecting to a single node, you can load balance across the entire cluster.~~
|
|
|
|
**Note:** The sniffer has been disabled for now due an [issue](https://github.com/elastic/elasticsearch-py/issues/2005#issuecomment-1645641960) with the 8.x elasticsearch client. The auth headers are not properly sent when enabling the sniffer. A working [patch](https://github.com/elastic/elasticsearch-py/issues/2005#issuecomment-1645641960) was shared and has been *mostly* converted in [helpers/sniff_patch.py](./helpers/sniff_patch.py) for the async client.
|
|
|
|
## Roadmap
|
|
- Create a module for RIR database ingestion *(WHOIS, delegations, transfer, ASN mapping, peering, etc)*
|
|
- Dynamically update the batch metrics when the sniffer adds or removes nodes.
|
|
- Fix issue with leftover FIFO files *(catch SIGTERM / SIGINT signals)*
|
|
- Create a working patch for the async client to properly send auth headers.
