こんにちは。たかやまです。

こちらはNetApp Cloud Insights – Cloud Secureを使ってみた(導入編)のつづきになります。
今回は実際にCloud Secureをランサムウェア攻撃をおこない検知してみたいと思います。

実際の検知画面

実際にCloudSecureが攻撃を検知した際の画面です。
こちらの画面から攻撃内容、攻撃者情報などを確認することができ、ユーザのアクセス制御やONTAP Snapshotの取得も行うことができます。

では、実際にランサムウェア攻撃を行いイベントを検知する流れを行っていきたいと思います。

やってみる

公式手順にある方法を使って、Linuxインスタンスがウイルス検知された場合の動作を確認してみたいと思います。

参考 : Cloud Secure: Simulating an Attack

事前準備

1.データコレクターの停止

すでにデータコレクターが動作している場合には、一旦停止します。

間違ったパスワードを入力し、接続を失敗させます。

ステータスがエラーになっていればOKです。

2.マウント

FSx for NetAppのボリュームをマウントをします。
今回はCloudSecure Agentに付属しているスクリプトで検知を行っていくので、マウントするサーバはCloudSecure Agentサーバを利用します。

NetAppの監視機能Fpolicyが必要なため、マウントの際はFpolicyがサポートするnfsバージョン4.0を指定してください。

Do not mount NFS version 4.1; it is not supported by Fpolicy.

Prepare the system

mkdir /fsx
mount -t nfs -o vers=4.0 <svm名>:<path> /fsx
実行ログ(展開)
$ sudo su -

# mkdir /fsx
# mount -t nfs svm-00490bef764612ee2.fs-06b3d2e945d454c19.fsx.ap-northeast-1.amazonaws.com:/taka_vol1 /fsx


3.事前ファイル作成

次に暗号化するダミーファイルを作成します。

cd /fsx
vi createfiles.sh
# 以下のスクリプトを記述
for i in {000..1000}
do
   echo hello > "File${i}.txt"
done
echo 3 > /proc/sys/vm/drop_caches ; sync

スクリプトを実行してファイルを作成します。
FSx for NetAppのボリュームに1000個ダミーファイルができると思います。

chmod 777 ./createfiles.sh
./createfiles.sh
実行ログ(展開)

# cd /fsx
# vi createfiles.sh
# chmod 777 ./createfiles.sh
# ./createfiles.sh
# ls
createfiles.sh  File0083.txt  File0167.txt  File0251.txt  File0335.txt  File0419.txt  File0503.txt  File0587.txt  File0671.txt  File0755.txt  File0839.txt  File0923.txt

CloudSecure確認

Cloud Secure確認 - All Activity -

ランサムウェア実行後、CloudSecureコンソールを確認してみます。

まずは、アクティビティを確認してみます。
左ペインのFORENSICS -> Activity Forensicsからアクティビティを確認できます。

今回の実行されたランサムウェアのアクティビティが確認できます。

①フィルター
項目ごとにフィルターをかけることができます。 今回はDeviceでフィルターをかけています。

②期間
表示する期間を指定できます。 カスタム期間で細かい日にち/時間指定も可能です。

③アクティビティタイプ
以下のアクティビティに対応しています。

アクティビティ 内容
Change Group Ownership ファイルやフォルダーのグループ所有権の変更
Change Owner ファイルまたはフォルダの所有者が別のユーザーに変更
Change Permission ファイルまたはフォルダの権限の変更
Create ファイルまたはフォルダーの作成
Delete ファイルまたはフォルダーの削除
Read ファイル読み込み
Read Metadata フォルダー監視オプションを有効にした場合
・Windowsでフォルダを開く
・Linuxでlsを実行
Rename ファイルまたはフォルダの名前変更
Write ファイルへのデータ書き込み
Write Metadata 権限が変更など、ファイルのメタデータ書き込み
Other Change 上記以外のイベント

④エンティティタイプ
ファイルの拡張子が表示されます。


Cloud Secure確認 - ALERTS -

次に実際に検知されたアラートを確認します。
左ペインのALERTSからアラート状況を確認できます。

①Potential Attacks
ここにはランサムウェアやサボタージュ攻撃と思われるイベントが出力されます。

②Warnings
こちらはユーザの動作に異常(ファイルアクセスの異常な増加など)が見られた場合に出力されます。


では実際に検知されたRansomware Attackのイベント詳細を見てみます。
AlertID/Potential Attacksのリンクをクリックすると詳細に飛ぶことができます。

詳細に飛ぶと、攻撃内容/関連ユーザ/攻撃対象ボリュームの情報が表示されます。
こちらが冒頭でご紹介した画面になります。

①攻撃内容
ここでは以下の情報を読み取ることができます。

  • 影響を受けるボリュームとファイルの数
  • 検出の概要
  • 攻撃中のファイルアクティビティを示すグラフ

他に以下の操作をこちらで行うことが可能です。

  • Manage Access/Restore Access : 関連ユーザのアクセスを制御
  • Re-Take Snapshots : ONTAPのSnapshot取得

②関連ユーザ
ここには攻撃者と見られる関連ユーザが表示されれます。
今回はCloudSecure側で自動的にユーザアクセスをBlockしていることがわかります。

実際にフォルダにアクセスしようとすると、FSx for NetAppからブロックされていることが確認できます。

③攻撃対象ボリューム
攻撃対象となっているボリュームの情報が表示されます。

Encrypted Filesのリンクをクリックすることで、実際にどのファイルが暗号化されているか確認することもできます。

ファイルリストア

ランサムウェア攻撃から検知までの一連の流れを確認できたので最後にファイルをリストアしたいと思います。

今回はONTAPのスナップショットを利用して、ファイルをリストアしたいと思います。
ONTAPではファイルシステム上に.snapshotという名前のサブディレクトリでsnapshotを管理しています。

ls -l /fsx/.snapshot
total 2280
drwxr-xr-x. 2 root root 774144 May 25 08:40 backup-0a6ace9bc41358822
drwxr-xr-x. 2 root root 774144 May 26 01:39 cloudsecure_attack_auto_1653529240504
drwxr-xr-x. 2 root root 774144 May 26 01:39 cloudsecure_manual_1653538840435

攻撃前のsnapshotが保管されている場合はこちらからファイルをコピーすることで復旧することができます。

ls /fsx
createfiles.sh.crypt  File0000.txt.crypt  ... File1000.txt.crypt #.cryptがついてるものは暗号化されている

ls /fsx/.snapshot/backup-0a6ace9bc41358822
createfiles.sh  File0000.txt  ... File1000.txt #.cryptがついていない暗号化前のファイルがあることがわかる

cp -p /fsx/.snapshot/backup-0a6ace9bc41358822/createfiles.sh /fsx
ls -l /fsx/createfiles*
-rwxrwxrwx. 1 root root 101 May 25 08:37 /fsx/createfiles.sh
-rw-r--r--. 1 root root 128 May 26 01:39 /fsx/createfiles.sh.crypt

参考 : NFS クライアントまたは SMB クライアント上の Snapshot コピーからファイルをリストアします

まとめ

CloudSecureの検知いかがだったでしょうか?

攻撃を検知して、自動でユーザアクセス制御/snapshotの取得をしてくれるなど非常に助かる機能だったかと思います。

ファイルリストアもサーバ管理者の対応なしでクライアント側から復旧できるのは楽でいいですね!

今回はLinuxの検知を試しましたが、Windowsやユーザの異常操作での検知などCloudSecureの機能を紹介しきれていないので、またブログにできたらと思います。

以上、たかやまでした。
