Introduction

Two months ago, one of my DigitalOcean instances started attacking another host with massive amounts of bogus traffic. I was notified by the abuse team at DO that my VPS was participating in a DDoS attack. I managed to track down that the attackers leveraged an RCE vulnerability in Elasticsearch to automatically download and run malware.

After re-building the box from scratch (with many improvements!), I created a honeypot called Elastichoney to measure how much this vulnerability is being exploited in the wild. Since then, I’ve had multiple sensors silently logging all attempts to exploit this vulnerability.

Here are the results.

Introduction

I recently wrote about an Elasticsearch RCE vulnerability that is being heavily exploited in the wild. To see what kind of attacks are taking place, I decided to write a simple honeypot designed to mimic a vulnerable Elasticsearch (ES) instance. Say hello to elastichoney!
