Script to help make sense of log output from popular SSH honeypot [Cowrie](https://github.com/cowrie/cowrie/). I think I got carried away with the specialized filtering settings. Only tested on my setup. Untested with Telnet. YMMV
# Usage
```
cowrieder.py <args> filepath
```
Options:
```
-h, --help show this help message and exit
-v, --verbose Make the output more verbose (print abridged logs for all logins where commands are run, not just the interesting ones)
-vv, --verboser Make the output even more verbose (print timestamp, event id, and message (if applicable) for all events)
-vvv, --verbosest Make the output even more verboserer (just group the input log by session id and dump it to pretty-printed JSON)
-P, --pings Print only "empty pings"
-F, --fails Print only failed logins
-L, --logins Print only "login pings"
-C, --commands Print only "command pings"
-S, --sessions Print only the cool interesting sessions that aren't any of that other stuff.
-r, --redact-ip Redact IP addresses by converting them to 16-character hashes
-i, --filter-ip FILTER_IP
Filter data to a specific IP or censored hash thereof
```
# Terminology
- "Empty ping": Client connected and made no attempt to log in
- "Login ping": Client logged in successfully and did nothing
- "Command ping": Client logged in successfully and only ran `uname`, `nproc`, and/or `echo`. In my experience "command pings" comprise most insances of a client successfully logging in and then bothering to run any commands
