Mythic 2.2 -> 2.3 Updates
If you want to look into all the new features available to you as a payload developer from an agent perspective, check out Agents 2.2 -> 2.3. The rest of this page is for higher-level updates and UI changes. Either way, to leverage these updates and to upgrade your Mythic instance, you will need to delete your current database
sudo ./mythic-cli database resetand then pull in the updates and
sudo ./mythic-cli mythic startagain.
Tasking agents from the web interface has changed slightly. When you start typing, there is no more automatic autocomplete dialog that pops up to help you out. Instead, as you're typing a command (or before you've typed any letters) you can press
Tabto cycle through available commands. For example, the
apfellagent has a
shell_elevatedcommand. If you start typing
sheland hit tab, you'll first get
shell_elevated, then back to
Once you have a command and you type a space, you can start tab-completing the command's parameters. The
shellcommand takes one parameter, a
command. If you type
shelland hit tab, the web interface will start providing the command parameters for you. In this case, you'd get
shell -command. At this point, without hitting
spaceagain, if you continue hitting tab, and if the
shellcommand had more parameters, the
Tabbutton would cycle through the available parameters until you hit
spaceand start typing out the values.
At any time, if a command has parameters, you can hit
shift+enterand cause the tasking modal to pop up.
To provide a form of conditional parameters for commands, Mythic now supports
parameter groups. This isn't a new concept - Microsoft's PowerShell does a similar thing. For a single command, you define which parameters are "grouped" together. This allows you to say that two parameters can't be used together, or that you can provide parameterA or parameterB depending on if parameterC is provided. The hard part was how to display this sort of meta information to the user.
When you're just typing out parameters on the command line and using the tab complete capabilities described in the previous section, then Mythic will automatically know which parameter group you're using. If you satisfy the requires for multiple parameter groups while using tab-complete, Mythic will just keep giving you options from all matching groups. Once you've supplied enough parameters to match only a single group, then Mythic will only give you parameter recommendations from that group. However, if you're using the popup modal, then Mythic will have a new dropdown menu at the top for selecting which parameter group you want to use. If you've started typing out parameters on the command line and hit
shift+enterto cause the modal to appear, if Mythic can determine which parameter group you're using, then that one will automatically populate the modal.
With the changes to how tasking is working, the old user interface will be decommissioned and you will have to use the new interface.
