novahot

novahot is a webshell framework for penetration testers. It implements a JSON-based API that can communicate with trojans written in any language. By default, it ships with trojans written in PHP, ruby, and python.

Beyond executing system commands, novahot is able to emulate interactive terminals, including mysql, sqlite3, and psql. It additionally implements "virtual commands" that make it possible to upload, download, edit, and view remote files locallly using your preferred applications.

Installation

Install the executable directly from npm:

[sudo] npm install -g novahot

Then seed a config file:

novahot config > ~/.novahotrc

Usage

  1. View the available trojans with novahot trojan list.

  2. Select a trojan in a language that is appropriate for your target, then copy its source to a new file. (Ex: novahot trojan view basic.php > ~/my-trojan.php)

  3. Change the control password in the newly-created trojan.

  4. Upload the trojan to a web-accessible location on the target.

  5. Configure target information in the targets property in ~/.novahotrc.

  6. Run novahot shell <target> to open a shell.

Shell Modes

Internally, novahot uses "modes" and "adapters" to emulate various interactive clients, currently including the mysql, psql (postgres), and sqlite3 clients.

To change novahot's mode, issue the appropriate "dot command":

.mysql { "username" : "mysql-user", "password" : "the-password", "database" : "the-database" }

(Connection parameters may be specified as JSON while changing modes, or alternatively saved as target configuration data in ~/.novahotrc.)

For example, the mysql mode makes it possible to directly run queries like the following:

mysql> SELECT ID, user_login, user_email, user_pass FROM wp_users;

There additionally exists a payload mode that can be used to POST arbitrary data to the trojan. See the wiki for more information.

Virtual Commands

novahot implements four "virtual commands" that utilize payloads built in to the trojans to extend the functionality of the shell:

download

download <remote-filename> [<local-filename>]

Downloads <remote-filename> to --download-dir, and optionally renames it to <local-filename> if specified.

upload

upload <local-filename> [<remote-filename>]

Uploads <local-filename> to the shell's cwd, and optionally renames <local-filename> to <remote-filename> if specified.

view

view <remote-filename> [<local-filename>]

Downloads <remote-filename> to --download-dir, and optionally renames it to <local-filename> After downloading, the file will be opened by the "viewer" application specified in the configs.

edit

edit <remote-filename>

Downloads <remote-filename> to a temporary file, and then opens that file for editing using the "editor" specified in the configs. Afterward, if changes to the file are saved locally, the file will be re-uploaded to the server automatically.
