VirusTotal CLI

Welcome to the VirusTotal CLI, a tool designed for those who love both VirusTotal and command-line interfaces. With this tool you can do everything you'd normally do using the VirusTotal's web page, including:

Retrieve information about a file, URL, domain name, IP address, etc.
Search for files and URLs using VirusTotal Intelligence query syntax.
Download files.
Manage your LiveHunt YARA rules.
Launch Retrohunt jobs and get their results.

And much more...

Getting started

As this tool use the VirusTotal API under the hood, you will need a VirusTotal API key. By signing-up with VirusTotal you will receive a free API key, however free API keys have a limited amount of requests per minute, and they don't have access to some premium features like searches and file downloads. If you are interested in using those premium features please contact us.

Installing the tool

For installing the tool you can download one the pre-compiled binaries we offer for Windows, Linux and Mac OS X, or alternatively you can compile it yourself from source code. To compile the program you'll need Go 1.14.x or higher installed in your system and type the following commands:

$ git clone https://github.com/VirusTotal/vt-cli
$ cd vt-cli
$ make install

NOTE: in order to use the vt binary, make sure the GOBIN is part of your PATH env variable:

$ export GOBIN=`go env GOPATH`/bin
$ export PATH=$PATH:$GOBIN

Mac OS

For Mac OS users, there's a brew formula available. Please note this is not maintained by VirusTotal.

$ brew install virustotal-cli

Windows

For Windows uses, there's a Winget manifest available. Please note this is not maintained by VirusTotal.

winget install VirusTotal.vt-cli

A note on Window's console

If you plan to use vt-cli in Windows on a regular basis we highly recommend you to avoid the standard Windows's console and use Cygwin instead. The Windows's console is very slow when printing large amounts of text (as vt-cli usually does) while Cygwin performs much better. Additionally, you can benefit of Cygwin's support for command auto-completion, a handy feature that Window's console doesn't offer. In order to take advantage of auto-completion make sure to include the bash-completion package while installing Cygwin.

Configuring your API key

Once you have installed the vt-cli tool you may want to configure it with your API key. This is not strictly necessary, as you can provide your API key every time you invoke the tool by using the --apikey option (-k in short form), but that's a bit of a hassle if you are going to use the tool frequently (and we bet you'll do!). For configuring your API key just type:

$ vt init

This command will ask for your API key, and save it to a config file in your home directory (~/.vt.toml). You can also specify your API key using the VTCLI_APIKEY environment variable. If you specify your API key in multiple ways, the --apikey option will have the highest precedence, followed by the VTCLI_APIKEY environment variable, the API key in the configuration file will be used as the last resort.

Use with a proxy

If you are behind a HTTP proxy you can tell vt-cli which is the address of your proxy server by multiple ways. One is using the --proxy option, like in:

$ vt --proxy http://myproxy.com:1234 <command>

You can also use the VTCLI_PROXY environment variable, or add the following line to the config file:

proxy="http://myproxy.com:1234"

Setup Bash completion

If you are going to use this tool frequently you may want to have command auto-completion. It saves both precious time and keystrokes. Notice however that you must configure your API as described in the previous section before following the steps listed below. The API is necessary for determining the commands that you will have access to.

Linux:

$ vt completion bash > /etc/bash_completion.d/vt

Mac OS X:

$ brew install bash-completion
$ vt completion bash > $(brew --prefix)/etc/bash_completion.d/vt

Add the following lines to ~/.bash_profile

if [ -f $(brew --prefix)/etc/bash_completion ]; then
. $(brew --prefix)/etc/bash_completion
fi

Cygwin:

Make sure the bash-completion package is installed (Cygwin doesn't installed it by default) and type:
```
$ vt completion bash > /usr/share/bash-completion/completions/vt
```

❗ You may need to restart your shell in order for autocompletion to start working.

Setup ZSH completion

The output script from vt completion zsh needs to be put somewhere under the $fpath directory. For example, .oh-my-zsh/completions directory:

$ mkdir /Users/$USERNAME/.oh-my-zsh/completions
$ vt completion zsh > /Users/$USERNAME/.oh-my-zsh/completions/_vt

Restart the shell.

Getting only what you want

When you ask for information about a file, URL, domain, IP address or any other object in VirusTotal, you get a lot of data (by default in YAML format) that is usually more than what you need. You can narrow down the information shown by the vt-cli tool by using the --include and --exclude command-line options (-i and -x in short form).

These options accept patterns that are matched against the fields composing the data, and allow you to include only a subset of them, or exclude any field that is not interesting for you. Let's see how it works using the data we have about http://www.virustotal.com as an example:

$ vt url http://www.virustotal.com

Notice that the returned data usually follows a hierarchical structure, with some top-level fields that may contain subfields which in turn can contain their own subfields. In the example above last_http_response_headers has subfields age, cache-control, content-length and so on, while total_votes has harmless and malicious. For refering to a particular field within the hierarchy we can use a path, similarly to how we identify a file in our computers, but in this case we are going to use a dot character (.) as the separator for path components, instead of the slashes (or backslashes) used by most file systems. The following ones are valid paths for our example structure:

last_http_response_headers.age
total_votes.harmless
last_analysis_results.ADMINUSLabs.category
last_analysis_results.ADMINUSLabs.engine_name

The filters accepted by both --include and --exclude are paths in which we can use * and ** as placeholders for one and many path elements respectively. For example foo.* matches foo.bar but not foo.bar.baz, while foo.** matches foo.bar, foo.bar.baz and foo.bar.baz.qux. In the other hand, foo.*.qux matches foo.bar.qux and foo.baz.qux but not foo.bar.baz.qux, while foo.**.qux matches foo.bar.baz.qux and any other path starting with foo and ending with qux.

For cherry-picking only the fields you want, you should use --include followed by a path pattern as explained above. You can also include more than one pattern either by using the --include argument multiple times, or by using it with a comma-separated list of patterns. The following two options are equivalent:

$ vt url http://www.virustotal.com --include=reputation --include=total_votes.*
$ vt url http://www.virustotal.com --include=reputation,total_votes.*

Here you have different examples with their outputs (assuming that vt url http://www.virustotal.com returns the structure shown above):

$ vt url http://www.virustotal.com --include=last_http_response_headers.server
- last_http_response_headers:
    server: "Google Frontend"

$ vt url http://www.virustotal.com --include=last_http_response_headers.*
- last_http_response_headers:
    age: "26"
    cache-control: "public, max-age=60"
    content-length: "7216"
    content-type: "text/html"
    date: "Tue, 24 Jul 2018 14:30:24 GMT"
    etag: "\"bGPKJQ\""
    expires: "Tue, 24 Jul 2018 14:31:24 GMT"
    server: "Google Frontend"
    x-cloud-trace-context: "131ac6cb5e2cdb7970d54ee42fd5ce4a"
    x-frame-options: "DENY"

$ vt url http://www.virustotal.com --include=last_analysis_results.**
- last_analysis_results:
    ADMINUSLabs:
      category: "harmless"
      engine_name: "ADMINUSLabs"
      result: "clean"
    AegisLab WebGuard:
      category: "harmless"
      engine_name: "AegisLab WebGuard"
      result: "clean"
    AlienVault:
      category: "harmless"
      engine_name: "AlienVault"
      result: "clean"

$ vt url http://www.virustotal.com --include=last_analysis_results.*.result
- last_analysis_results:
    ADMINUSLabs:
      result: "clean"
    AegisLab WebGuard:
      result: "clean"
    AlienVault:
      result: "clean"

$ vt url http://www.virustotal.com --include=**.result
- last_analysis_results:
    ADMINUSLabs:
      result: "clean"
    AegisLab WebGuard:
      result: "clean"
    AlienVault:
      result: "clean"

Also notice that _id and _type are also field names and therefore you can use them in your filters:

$ vt url http://www.virustotal.com --include=_id,_type,**.result
- _id: "1db0ad7dbcec0676710ea0eaacd35d5e471d3e11944d53bcbd31f0cbd11bce31"
  _type: "file"
  last_analysis_results:
    ADMINUSLabs:
      result: "clean"
    AegisLab WebGuard:
      result: "clean"
    AlienVault:
      result: "clean"

The --exclude option works similarly to --include but instead of including the matching fields in the output, it includes everything except the matching fields. You can use this option when you want to keep most of the fields, but leave out a few of them that are not interesting. If you use --include and --exclude simultaneously --include enters in action first, including only the fields that match the --include patterns, while --exclude comes in after that, removing any remaining field that matches the --exclude patterns.
