Arachne is a webshell payload for Windows (aspx) and Linux (php). When run alone, the arachne container reaches out to the specified URL to issue tasking. When an agent links via P2P to an arachne agent, then that agent will remotely reach out to the specified URL to issue tasking.
This version currently supports Mythic 2.3.+ and will update as necessary. It will not work with Mythic 2.2 and lower.
When it's time for you to test out your install or for another user to install your agent, it's pretty simple. Within Mythic you can run the mythic-cli
binary to install this in one of three ways:
sudo ./mythic-cli install github https://github.com/user/repo
to install the main branchsudo ./mythic-cli install github https://github.com/user/repo -b branchname
to install a specific branch of that reposudo ./mythic-cli install folder /path/to/local/folder/cloned/from/github
to install from an already cloned down version of an agent repoNow, you might be wondering when should you or a user do this to properly add your agent to their Mythic instance. There's no wrong answer here, just depends on your preference. The three options are:
sudo ./mythic-cli payload start agentName
and if that agent has its own special C2 containers, you'll need to start them too via sudo ./mythic-cli c2 start c2profileName
).sudo ./mythic-cli mythic start
. That script will first stop all of your containers, then start everything back up again. This will also bring in the new agent you just installed.sudo ./mythic-cli mythic start
. The agent icon for Arachne is from flaticon and created by jemastock.
