Step 4 : Attacking and Preventing first Attack

For demonstration purposes we are creating a docker container with vulnerable application and running it with our already downloaded K2 Ruby language agent.

docker run -v /opt/k2-ic:/opt/k2-ic -e K2_OPTS="/opt/k2-ic/k2-ruby-agent.gem" -itd -p 3000:3000 --name demo-app k2cyber/ic-test-application:ruby-demo

‌SQL Injection Attack

curl 'http://localhost:3000/sqli-attackcase?input=abc%27+or+%271%27%3D%271' -H 'Connection: keep-alive' -H 'Upgrade-Insecure-Requests: 1' -H 'DNT: 1' -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.105 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9' -H 'Referer: http://localhost:3000/sqli/sqlinjectionattackcase' -H 'Accept-Language: en-US,en;q=0.9,hi;q=0.8' --compressed --insecure

Now you can go to Attacks section in K2 Manager and see there will be one attack captured by K2 Manager or Alternatively go to Attacks | K2 Portal.

Congratulations you've successfully prevented SQL injection attack.
