Bash script to find Apache Misfits

There are bad web robots (or crawlers) that scan for vulnerable wordpress admin panels, phpMyAdmin, or other popular scripts.

If you've been affected by these bad robots, spiders, or crawlers your Apache error logs will look something like this:

grep -Hni phpmyadmin /var/log/apache2/error.log

Here's a section of Apache's error.log from a single attacker:

Have you ever wondered what country these bad robots were connecting from?

Wonder no more!

I wrote a bash script that will geo locate all Apache Misfits in a jiffy*. Unlike many of these ugly solutions at commandlinefu, my script doesn't require you to scrape geoip-lookup websites, so it runs much faster.

Presenting: misfits.sh

You will first need to install geoip-bin from the Debian repositories.

apt-get update && apt-get install geoip-bin

Grab my code:

cd git clone https://gist.github.com/d77bd25be45c1865ad3b.git cd d77bd25be45c1865ad3b chmod +x misfits.sh

Note: You can run this script without being root but you'll need to make a copy of your apache error.log.

To run:

Print a long unformatted list from geoiplookup: (pretty useless, imho) ./misfits.sh

Example output:

GeoIP Country Edition: JP, Japan GeoIP Country Edition: CN, China GeoIP Country Edition: CN, China GeoIP Country Edition: CN, China GeoIP Country Edition: CN, China ...

Print a simplified list of stats: ./misfits.sh stats

Example output:

... 7 IN, India 6 TH, Thailand 6 KR, Korea, Republic of 6 HK, Hong Kong 5 ES, Spain 5 CZ, Czech Republic 4 RO, Romania 4 AU, Australia 3 PE, Peru ...

Print the Top Ten Offending Countries: ./misfits.sh top10

327 US, United States 191 CN, China 62 IP Address not found 47 RU, Russian Federation 37 NL, Netherlands 28 FR, France 22 UA, Ukraine 21 DE, Germany 11 GB, United Kingdom 9 CA, Canada

Enjoy!

* actual running time varies, of course, depending on the size of error.log. Here's my running time:
