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.

[[.Bold]][[.Underline]]Sorting[[.Normal]]
Directory and file listings are sorted by name in ascending order by default. Listings can also be sorted by size (-s) and modified time (-m). All sorts can be reversed with -r.
[[.Bold]][[.Underline]]Filters[[.Normal]]
Filters are a way to limit search results to directory and file names matching given criteria.
Filters are specified after the path. A blank path will filter on names in the current directory. For example:
/etc/passwd will display the listing for /etc/passwd. "/etc/" is the path, and "passwd" is the filter.
Directory and file listings can be filtered using the following patterns:
'*': Wildcard, matches any sequence of non-path separators (slashes)
Example: n*.txt will match all file and directory names starting with n and ending with .txt
'?': Single character wildcard, matches a single non-path separator (slashes)
Example: s?iver will match all file and directory names starting with s followed by any non-separator character and ending with iver.
'[{range}]': Match a range of characters. Ranges are specified with '-'. This is usually combined with other patterns. Ranges can be negated with '^'.
Example: [a-c] will match the characters a, b, and c. [a-c]* will match all directory and file names that start with a, b, or c.
^[r-u] will match all characters except r, s, t, and u.
If you need to match a special character (*, ?, '-', '[', ']', '\\'), place '\\' in front of it (example: \\?).
On Windows, escaping is disabled. Instead, '\\' is treated as path separator.
