vaas

An SDK to easily utilize G DATA VaaS.

Verdict-as-a-Service (VaaS) is a service that provides a platform for scanning files for malware and other threats. It allows easy integration in your application. With a few lines of code, you can start scanning files for malware.

What does the SDK do?

It gives you as a developer a functions to talk to G DATA VaaS. It wraps away the complexity of the API into 3 basic functions.

for_sha256

If you calculate the sha256 for a file, you can request that sha256 against G DATA VaaS. It's the fastest way to get a verdict from our service.

for_url

If you want to request if a file behind a URL is safe, you can specify the URL as well. Depending on the file size, the duration for the analysis can vary.

for_file

You can also ask for a file itself. You will still get the benefit of a fast verdict via Sha256 because the SDK will do that for you first. But additionally, if we don't know the file, the file will get uploaded and (automatically) analyzed by us.

How to use

Installation

This gem works only on a Linux distribution!

gem install vaas

Require

require 'async'
require 'vaas/client_credentials_grant_authenticator'
require 'vaas/vaas_main'

Request a verdict

Authentication & Initializing:

authenticator = VAAS::ClientCredentialsGrantAuthenticator.new(
  CLIENT_ID,
  CLIENT_SECRET,
  TOKEN_URL,
  SSL_VERIFICATION
)
vaas = VAAS::VaasMain.new
token = authenticator.get_token

Verdict Request for SHA256:

Async do
  vaas.connect(token)
  sha256 = "275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f"
  verdict = vaas.for_sha256(sha256) # starts a task
  puts verdict.wait.verdict # await task
  vaas.close
end

Verdict Request for a file:

Async do
  vaas.connect(token)
  path = "/path/to/file"
  verdict = vaas.for_file(path) # starts a task
  puts verdict.wait.verdict # await task
  vaas.close
end

Verdict Request for a URL:

Async do
  vaas.connect(token)
  url = "https://www.gdatasoftware.com/oem/verdict-as-a-service"
  verdict = vaas.for_url(url) # starts a task
  puts verdict.wait.verdict # await task
  vaas.close
end

Verdict Object:

# A verdict object has a sha256, verdict and guid
sha256 = verdict.sha256
detection = verdict.verdict
guid = verdict.guid
