VirusTotalをコマンドラインから利用する

VirusTotalというオンラインスキャナがあります．不安なファイルなどをここでスキャンするとたくさん(現在は54)のエンジンでスキャンしてその結果を確認できます． 複数のエンジンを利用するのでチェック漏れが少ないので安心感があります．（絶対ではない）

このVirusTotalにはAPIやデスクトップアプリケーション(Win/Mac/Linux)があります．これを利用してコマンドラインからスキャナにファイルを投げたり結果を確認したりしてみます．

※利用するときデータをVirusTotalのサーバにアップロードする必要がありますが，アップロードされたデータはVirusTotalとの契約者が利用できるようになっているので人に見られたら困るものや仕事のファイルなどには利用しないほうがいいでしょう．もしそういうものをたくさんのエンジンでスキャンしたい場合はMetadefender Coreという製品などを検討するといいかもです．

導入

必要パッケージの導入

ビルドに必要なパッケージを導入します．Debian/Ubuntuでは以下のものが必要です．

$ sudo apt install build-essential automake autoconf libtool libjansson-dev libcurl4-openssl-dev git

build

sourceを入手してbuildします．

$ git clone https://github.com/VirusTotal/c-vtapi.git
$ cd c-vtapi
$ ./conigure --prefix=$HOME/usr/local
$ make
$ make install

続いてexampleをbuildします．(この中に簡易的なコマンドがあるのでこれを利用します．)

$ autoreconf -fi
$ ./configure --enable-examples
$ make

API Keyの入手

VirusTotalのコミニュティにサインアップして，API Keyを入手しておきます．

たまに使うのでですがブラウザがなくても利用できて便利そうです :)
ちなみにGUIもあるのでGUIで利用したい人はそちらもBUILDすると幸せになれるかもしれません．
