# Repository Guidelines
## Project Structure & Module Organization
- `client/` holds the CLI client and interactive commands.
- `server/` contains the server runtime, C2 logic, configs, and web assets.
- `implant/` is the implant runtime and transport implementations.
- `protobuf/` stores protobuf definitions and generated Go types.
- `util/` is shared helpers (crypto, encoders, minisign, etc.).
- `docs/sliver-docs/` is the Next.js documentation site and prebuild scripts.
- `vendor/` is the vendored Go dependency tree used by builds.
- Build outputs land in the repo root as `sliver-client*` and `sliver-server*`.
## Build, Test, and Development Commands
- `make` builds server + client using vendored modules and runs `go-assets.sh`.
- `make client` builds a CGO-free client; `make debug` keeps symbols.
- `make pb` regenerates protobuf stubs from `protobuf/`.
- `./go-tests.sh` runs the curated Go test suite with build tags.
- Docs site: `cd docs/sliver-docs && npm install && npm run dev` for local dev; `npm run build` for a static build.
- Go toolchain: the Makefile enforces Go >= 1.24.
## Coding Style & Naming Conventions
- Run `gofmt` on all Go code; keep package names lowercase and idiomatic.
- Avoid `CGO` and empty interfaces; prefer explicit types and interfaces.
- Do not import `server` packages from `client`.
- If `math/rand` is required, import it as `insecureRand` and avoid security use.
## Testing Guidelines
- Go tests follow standard `_test.go` naming within each package.
- Prefer `docker build --target test --build-arg GO_TESTS_FLAGS=--skip-generate .`
- Add or update tests when behavior changes; some server packages run longer tests.
## Commit & Pull Request Guidelines
- Commits must be signed for PRs to `master`; work in a feature branch.
- Commit subjects are short and imperative (e.g., "Fix ...", "Add ...", "Update ...", "Bump ...").
- Changes to `vendor/` should be in a distinct commit.
- PRs should link the tracking issue, note tests run, and confirm `gofmt` plus unit tests as applicable.
## Security Notes
- Default to secure configuration; fail closed rather than open.
- Avoid insecure algorithms (MD5/SHA1/AES-ECB); prefer AES-GCM and modern curves.
- Treat user input as untrusted: canonicalize paths and use restrictive file permissions.

# Sliver
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).

# client
Client
=======
## Overview
This directory contains the client implementation, pretty much all of this code is also used by the server console.
Main command-line client for interacting with and administering Sliver servers. Provides the Cobra entrypoint and aggregates console, command, and transport subsystems.
__Important:__ No code in this directory can import any code from `server/`.
## Go Files
- `main.go` – Entry point that initializes the CLI, processes flags, and launches the interactive console.
## Sub-packages
- `assets/` – Manages embedded client asset manifests such as operator profiles, settings, and armory catalogs. Handles serialization, bundling, and lookup of static client metadata.
- `cli/` – Defines the Cobra root command and CLI initialization for the Sliver client binary. Sets up persistent flags, environment bootstrapping, and command wiring.
- `command/` – Shared registration glue, scaffolding, and helpers for Sliver client console command groups. Hosts common utilities for binding Cobra commands to RPC-backed actions.
- `console/` – Renders the interactive console UI, logging, and terminal helpers for the client. Coordinates readline behavior, prompt styling, and message formatting.
- `constants/` – Centralizes constants shared across the client runtime and command packages. Captures strings, flag names, and feature toggles used throughout the CLI.
- `core/` – Maintains client application state, background workers, and RPC coordination. Orchestrates session tracking, event streams, and health checks.
- `credentials/` – Credential management utilities including sniffers and import helpers for operators. Provides parsers, storage helpers, and output formatting for recovered secrets.
- `licenses/` – Holds embedded license metadata bundled with the client distribution. Supplies license retrieval utilities used for attribution commands.
- `overlord/` – Supervises long-running client jobs, scheduling, and task orchestration. Tracks job lifecycle events and exposes status updates to the console.
- `packages/` – Deals with packaged extensions and module discovery for the client. Scans, validates, and caches extension manifests and assets.
- `spin/` – Lightweight terminal spinner utilities used for progress feedback. Wraps spinner styles and timing helpers shared across commands.
- `tcpproxy/` – Implements the local TCP proxy used for port forwarding from the client side. Manages listener lifecycles, connection pumps, and cleanup hooks.
- `transport/` – Client-side transports and RPC wiring to communicate with Sliver servers. Builds authenticated gRPC clients, TLS dialers, and reconnect logic.
- `version/` – Build-time version and semantic metadata for the client binary. Exposes git information, release channels, and helper formatters.
* `assets/` - Static asset files and management code (e.g. client configs)
* `cli/` - Command line interface implementation
* `command/` - Console command implementations
* `constants/` - Various shared constant values
* `core/` - Client state management
* `licenses/` - Open source licenses
* `spin/` - Console spinner library
* `tcpproxy/` - Local TCP proxy listener code
* `transport/` - Wires the client to the server
* `version/` - Version information
* `main.go` - Entrypoint

# client/assets
Assets
======
## Overview
Manages embedded client asset manifests such as operator profiles, settings, and armory catalogs. Handles serialization, bundling, and lookup of static client metadata. Core logic addresses aliases, armories, C2 profiles, and extensions within the assets package.
## Go Files
- `aliases.go` – Provides helpers for discovering, installing, and reading alias manifests shipped with the client.
- `armories.go` – Loads configured armory definitions and persists operator customizations.
- `assets.go` – Central entry point that exposes asset directories, lazy initialization, and filesystem utilities.
- `c2profiles.go` – Embeds default HTTP C2 profile templates and exposes lookup utilities.
- `config.go` – Tracks client configuration paths and manages persistence of runtime options.
- `extensions.go` – Handles embedded extension manifests and supports lookup by command name.
- `settings.go` – Stores default console settings and manages serialization to disk.

# client/cli
CLI
===
## Overview
Defines the Cobra root command and CLI initialization for the Sliver client binary. Sets up persistent flags, environment bootstrapping, and command wiring. Core logic addresses console, implant, import, and version within the cli package.
## Go Files
- `cli.go` – Builds the root Cobra command, wires global flags, and starts the console UI.
- `config.go` – Parses CLI configuration files and environment variables used during startup.
- `console.go` – Launches the interactive console mode and handles profile selection.
- `implant.go` – Implements CLI entry points for implant-specific operations without launching the console.
- `import.go` – Provides import routines for bringing external state into the client (e.g., implants or loot).
- `version.go` – Prints version/build information for the CLI binary.
This package implements the Sliver client cli.

# client/command
Command
=======
## Overview
This package contains all of the client command implementations that are shared between the client and the server console.
Shared registration glue, scaffolding, and helpers for Sliver client console command groups. Hosts common utilities for binding Cobra commands to RPC-backed actions. Core logic addresses sliver within the command package.
### Developers
## Go Files
- `command.go` – Provides helpers for binding Cobra commands, flag sets, and visibility filters into the client command tree.
- `server.go` – Defines the server menu composition, wiring each server-side command group onto the root console structure at runtime.
- `main.go` – Builds the implant/Sliver menu, attaching per-target command groups and loading alias/extension manifests before exposure.
## Sub-packages
- `alias/` – Implements the 'alias' command group for the Sliver client console.
- `armory/` – Implements the 'armory' command group for the Sliver client console.
- `backdoor/` – Implements the 'backdoor' command group for the Sliver client console.
- `beacons/` – Implements the 'beacons' command group for the Sliver client console.

- `crack/` – Implements the 'crack' command group for the Sliver client console.
- `creds/` – Implements the 'creds' command group for the Sliver client console.
- `cursed/` – Implements the 'cursed' command group for the Sliver client console.
- `dllhijack/` – Implements the 'dllhijack' command group for the Sliver client console.
- `environment/` – Implements the 'environment' command group for the Sliver client console.
- `exec/` – Implements the 'exec' command group for the Sliver client console.
- `exit/` – Implements the 'exit' command group for the Sliver client console.
- `extensions/` – Implements the 'extensions' command group for the Sliver client console.
- `filesystem/` – Implements the 'filesystem' command group for the Sliver client console.
- `flags/` – Implements the 'flags' command group for the Sliver client console.
- `generate/` – Implements the 'generate' command group for the Sliver client console.
- `help/` – Implements the 'help' command group for the Sliver client console.
- `hosts/` – Implements the 'hosts' command group for the Sliver client console.
- `info/` – Implements the 'info' command group for the Sliver client console.
- `jobs/` – Implements the 'jobs' command group for the Sliver client console.
- `kill/` – Implements the 'kill' command group for the Sliver client console.
- `licenses/` – Implements the 'licenses' command group for the Sliver client console.
- `loot/` – Implements the 'loot' command group for the Sliver client console.

- `websites/` – Implements the 'websites' command group for the Sliver client console.
- `wireguard/` – Implements the 'wireguard' command group for the Sliver client console.
General guidance on the structure of this package:
* One command per file and the name of the file should reflect the command it implements (or there about, trivial commands can go into the same file). This makes it easy to find where a command implementation lives within a package or to search by file name if it is not clear which package implements a given command.
* The root command, and reused code should go into the file named after the command
* For example, code shared between the `generate` and the `regenerate` command should go in `generate.go`, and any `regenerate` specific code should go in `regenerate.go`
* Command entrypoint functions should have the suffix `Cmd` e.g., `GenerateCmd` is the entrypoint for `generate`
* Command entrypoints should always a function signature of `func (ctx *grumble.Context, con *console.SliverConsoleClient)`
* Functions that are only ever exported for other commands to use should go in a `helpers.go`, if the function is used internally and exported follow the guidance above on shared code.

# client/command/aka
## Overview
Implements the 'aka' command group for the Sliver client console. "Aka"s are
command aliases (like 'alias' in 'bash') that allow operators to specify
shorthand commands and default arguments for commonly used commands.
### Examples:
- `aka create bg background`: Allows an operator to run `bg` from the implant
menu to quickly move back to the server menu
- `aka create execw execute -o "C:\Windows\System32\cmd.exe" /c`: Shorthand for
executing binaries on Windows targets like: `execw arp -a`
## Go Files
- `commands.go` – Wires Cobra commands for listing, creating, and deleting command aliases in the client console.
- `create.go` – Handles creating command aliases to use by the client.
- `delete.go` – Removes command aliases currently tracked by the client.
- `hook.go` – The main hooking logic to intercept commands ran by the client console. The hook will intercept processing before hitting the Cobra tree to transform the command alias to a full command with default arguments from the command alias and user-provided arguments to the alias.
- `list.go` - Lists the current command aliases tracked by the client.
- `storage.go` - Supports the saving of aliases to disk to keep between runs of the client.

# client/command/alias
## Overview
Implements the 'alias' command group for the Sliver client console. Handlers map Cobra invocations to alias workflows such as install, load, and remove.
## Go Files
- `alias.go` – Implements runtime alias management, printing installed aliases and exposing tab-completion helpers.
- `alias_test.go` *(tests)* – Exercises manifest parsing logic to ensure alias metadata is interpreted correctly.
- `commands.go` – Wires Cobra commands for listing, installing, loading, and removing aliases into the client console.
- `install.go` – Handles installing alias bundles from directories or archives, writing manifests and payload artifacts to disk.
- `load.go` – Loads alias manifests, validates target compatibility, and registers commands against the active console.
- `remove.go` – Removes installed aliases, prompting for confirmation and deleting associated on-disk assets.

# client/command/armory
## Overview
Implements the 'armory' command group for the Sliver client console. Handlers map Cobra invocations to armory workflows such as install, manage, parsers, and search.
## Go Files
- `armory.go` – Maintains the armory cache lifecycle, fetching package metadata, verifying signatures, and presenting bundle listings.
- `armory_test.go` *(tests)* – Placeholder for armory command tests; currently used to keep the package's test harness wired up.
- `commands.go` – Declares the Cobra command hierarchy for armory actions and binds shared flag/completion plumbing.
- `install.go` – Resolves dependencies and installs aliases or extensions from cached metadata, prompting when overwriting existing packages.
- `manage.go` – Implements management helpers for viewing, adding, verifying, and persisting armory configurations.
- `parsers.go` – Provides parsers and HTTP helpers for retrieving armory indexes and packages, including Minisign verification.
- `search.go` – Implements the regex-driven search command that filters cached armory packages.
- `update.go` – Calculates available package updates, presents options to the user, and orchestrates update installation.

# client/command/beacons
Beacons
========
## Overview
Implements the 'beacons' command group for the Sliver client console. Handlers map Cobra invocations to beacons workflows such as prune, RM, and watch.
## Go Files
- `beacons.go` – Retrieves beacon inventories and renders them in tabular form with optional filtering.
- `commands.go` – Declares the beacons command set, binds flags/completions, and wires subcommands like prune, rm, and watch.
- `helpers.go` – Provides helper RPC wrappers for selecting, fetching, and listing beacons.
- `prune.go` – Implements the prune routine that removes stale beacon entries via the backend API.
- `rm.go` – Removes a specific beacon by ID, coordinating confirmation and RPC teardown.
- `watch.go` – Streams beacon events in a watch loop, handling cancellation and console interaction.
This package implements the beacons command, which can be used to list and interact with beacons.

# client/command/creds
## Overview
Implements the 'creds' command group for the Sliver client console. Handlers map Cobra invocations to creds workflows such as ADD, hash types, RM, and select.
## Go Files
- `add.go` – Adds credentials to the client store via interactive or flag-based input.
- `commands.go` – Registers credential management commands and subcommands.
- `creds.go` – Lists stored credentials and formats them for display.
- `hash-types.go` – Enumerates supported hash types and their identifiers.
- `rm.go` – Removes credentials by ID or filter from the store.
- `select.go` – Selects credentials for use in other workflows, updating defaults.

# client/command/cursed
## Overview
Implements the 'cursed' command group for the Sliver client console. Handlers map Cobra invocations to cursed workflows such as cursed chrome, cursed console, cursed cookies, and cursed edge.
## Go Files
- `commands.go` – Exposes the cursed command suite and binds individual subcommands for supported targets.
- `cursed-chrome.go` – Launches or hijacks Chrome debugging sessions, locating executables and wiring remote control.
- `cursed-console.go` – Provides the interactive cursed console experience atop Chrome DevTools sessions.
- `cursed-cookies.go` – Fetches and displays browser cookies from an active cursed session.
- `cursed-edge.go` – Mirrors the Chrome workflow for Microsoft Edge, including process discovery logic.
- `cursed-electron.go` – Drives cursed interactions with arbitrary Electron apps, validating binaries and starting injected sessions.
- `cursed-rm.go` – Removes cursed sessions from the client cache and tears down associated resources.
- `cursed-screenshot.go` – Captures screenshots from a cursed browser context via DevTools APIs.
- `cursed.go` – Manages the cursed process registry, selection helpers, and remote debugger configuration defaults.
