Sliver
======
Sliver is an open source cross-platform adversary emulation/red team framework, it can be used by organizations of all sizes to perform security testing. Sliver's implants support C2 over Mutual TLS (mTLS), WireGuard, HTTP(S), and DNS and are dynamically compiled with per-binary asymmetric encryption keys.
Sliver is an open source cross-platform adversary emulation/red team framework, it can be used by organizations of all sizes to perform security testing. Sliver's implants support C2 over Mutual TLS (mTLS), WireGuard, HTTP(S), and DNS. Implants are dynamically compiled with unique X.509 certificates signed by a per-instance certificate authority generated when you first run the binary.
The server and client support MacOS, Windows, and Linux. Implants are supported on MacOS, Windows, and Linux (and possibly every Golang compiler target but we've not tested them all).

Extensions
===========
Allows to load and execute 3rd party extensions.
Extensions directory structures can be arbitrary, however in the root of the directory or .tar.gz there
must be a `extension.json` or a `alias.json` file. All paths are relative to the manifest/root directory,
parent directories are not allowed. Only files listed in the manifest are copied, any other files will
be ignored.
```shell
/path/to/extension/folder/
├── extension.json
└── windows
│ └── extension.x86.dll
│ └── extension.x64.dll
└── linux
│ └── extension.x86.so
│ └── extension.x64.so
└── darwin
└── extension.x86.dylib
└── extension.x64.dylib
```
Here's an example manifest (i.e., the `extension.json` or a `alias.json`):
```json
{
"name": "foo",
"version": "1.0.0",
"extension_author": "ac1d-burn",
"original_author": "zer0-cool",
"repo_url": "https://github.com/foo/bar",
"help": "Help for foo command",
"entrypoint": "RunFoo",
"init" :"NimMain",
"depends_on": "bar",
"files": [
{
"os": "windows",
"arch": "amd64",
"path": "extension.x64.o",
}
],
"arguments": [
{"name": "pid", "type": "int", "desc": "pid", "optional": false},
]
}
```
The structure is the following one:
- `name`: name of the extension, which will also be the name of the command in the sliver client
- `help`: the documentation for the new command
- `entrypoint`: the name of the exported function to call
- `files`: a list of object pointing to the extensions files to load for each architectures and operating systems
- `init`: the initialization function name (if relevant, can be omitted)
- `arguments`: an optional list of objects (for DLLs), but mandatory for BOFs
- `depends_on`: the name of an extension required by the current extension (won't load if the dependency is not loaded)
The `type` of an argument can be one of the following:
- `string`: regular ASCII string
- `wstring`: string that will be UTF16 encoded
- `int`: will be parsed as a 32 bit unsigned integer
- `short`: will be parsed as a 16 bit unsigned integer
- `file`: a string to a file path on the client side which content will be passed to the BOF
Wraps external DLLs/tool in Sliver console commands.
