Bellingcat website launch contest notes

So Bellingcat held a contest as part of their new website launch where you had to find a hidden symbol on the site in order to find the new website, and the first 25 people to do so could claim a prize (a limited edition Bellingcat hoodie).

I was curious to participate, and lucky/quick enough to be one of the 25 (after a false start I got there in a bit under 40 minutes), however I wasn't having a bar of doing it properly so I used ahem alternative methods. The rationale is that I wanted to see if I could attack it in a methodical way, reduce reliance on chance and my dumb brain, while still being competitve in terms of speed.

Wat

The Garmin Etrex 10 is an entry level hand-held GPS receiver with limited features, however with a bit of extra work it can be pretty bloody good for Geocaching (the notes here are possibly useful for other purposes too). While the unit has limited storage available, and doesn't officially support custom or even detailed mapping, it is possible to load your own maps (detailed maps will only cover smallish areas however).

Why

For all it's limitations, the Garmin Etrex 10 is really suitable for new cachers / recreational GPS users looking to get their first device. Aside from the very basic features you'd expect in an entry level hiking GPS, it has built-in support for Geocaching, it's relatively cheap (as of 2020 it's less than 1/2 the price of the Etrex 20), it's small + light, it's probably a bit better than your phone GPS outside of urban areas, and you can load custom maps with a bit of effort.

I find that I need to update my maps maybe once per year or so, and this gist is available mainly s

# Masscan - common ports are 80, 81, 8000, 8080, 8081, 8090, 8888, 9000, 9001
# I do it like this: 
# sudo masscan --banners --source-ip <IP not in use on your network> --rate <how fast you can scan>\ 
# -iL <list of CIDR to scan> -p <that list of ports above> -oJ <output file.json>

Doing a big big big masscan and grabbing headers, currently have targets in mind for a project but wanted to find a way to explore the other stuff active on the same ports. Used this deeply terrible one-liner to split up the HTTP banners into tokens and then count token frequency.

fgrep -i http masscan.json | sed 's/[,]$//'\
 | jq -s ".[].ports[].service.banner" | sed 's/[";:,<>()]//g'\
 | sed "s/[']//g" | sed -E 's/([\\]r|[\\]n)+/ /g'\
 | sed 's/[\/=]/ /g' | awk '{ for (i=1; i<=NF; i++) { print $i}}'\
 | tr '[:upper:]' '[:lower:]' | grep -E '^.{4,}$'\

# Basic scraper to pull IP CIDRs from the RIPE API. Currently hardcoded to grab
# all public Australian AS Numbers, could be quickly modified to scrape based on
# on other criteria. Only currently does IPV4, again quick to modify for v6.

# Runs on 8 threads because that's the max allowed concurrent requests for the

#  Simple HTTP server that  supports file upload  for moving data around

#  as I've tried  (badly) to port it to Python 3, code golf it, and make
#  It a  little more  robust. I was also able to  strip out a lot of the
