介绍

# Log4Shell Honeypot

## Detection Rule

The container responds with a plain login form.

Any request will be inspected for `${` (headers and body).

This triggers a critical-level log with the entire request (as a dict with tuples, which is JSON-ish).

## Event log

The event log will look like this (but as a single line):

```yaml
CRITICAL:<HONEYPOT_NAME>:{
  'honeypot': '<HONEYPOT_NAME>', 
  'source': '172.17.0.1',
  'headers': EnvironHeaders([
    ('Host', 'localhost:8080'),
    ('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:96.0) Gecko/20100101 Firefox/96.0'),
    ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8'),

```
