** Plugin UIs are still being updated so this will remain a pre-release until then

New UI

We are re-imagining the way end users interact with CALDERA. This includes large updates to the UI.
Included is a new abilities screen to easily manage your extensive library.

API v2

Calling all builders! For all those who build on the CALDERA platform we have a whole new API with full documentation. Currently docs are available once you start up the server. Look for a link at the bottom of the navigation menu "api docs"

C2 Channels

We've introduced some new C2 channels, including:

• Slack
• SSH tunneling
• FTP

Agent Updates

• Sandcat agent support for new C2 channels (Slack, FTP, SSH tunneling)
• New “proc” executor for Sandcat that will directly spawn processes using a provided executable path and arguments, rather than calling via PowerShell, sh, or cmd.
• Sandcat agents can remove executors or update executor binary paths
• Manx agents can properly run commands of longer durations.

Knowledge Service

New service created to better manage facts and information during an operation or when performing analysis

File upload/download encoding

Supports basic file encoding (plaintext and base64) for payload downloads and file uploads. To encode a downloaded payload or uploaded file, set the “x-file-encoding" HTTP header accordingly when making the download/upload request. Available data encoders are defined as Python modules in app/data_encoders. Currently supported encoders are “plain-text” and “base64”

Auth service

Add support for custom login handlers, as well as a new SAML authentication plugin.

Other Changes

• Dropped python 3.6 support and now testing for 3.7, 3.8, and 3.9
• We now support all browsers, Google Chrome is no longer the only supported browser
