貨物窃盗のデジタルトランスフォーメーション
サイバー犯罪グループは、遠隔監視管理(RMM)ツールを送り込み、システムを制御することで、運送および物流企業を侵害し、偽の貨物を掲載し、配送の入札を行い、物理的な貨物を盗んで金銭的利益を得ています。
調査
この脅威クラスターは、少なくとも2025年6月以来活動しており、ScreenConnect、SimpleHelp、PDQ Connect、Fleetdeck、N‑able、LogMeIn ResolveといったRMM製品を使用しています。初期のアクセスは侵害された荷物掲示板アカウントやフィッシングメールによって行われ、役者はネットワークの偵察を行い、WebBrowserPassViewのような資格情報収集ツールを展開します。その後、業界のワークフローを悪用して詐欺的な貨物を投稿し、盗難を調整します。このキャンペーンは、署名された正当なRMMインストーラーを利用して検出を回避しており、以前のNetSupportなどの情報窃取ツールの配信活動と関連付けられています。
緩和
組織は、承認されていないRMMソフトウェアのインストールを制限し、既知のRMMドメインとシグネチャーに関するネットワーク検出ルールを実装し、外部送信者からのメールで提供された実行可能ファイルとMSIファイルをブロックし、荷物掲示板とメールアカウントに多要素認証を強制し、フィッシングの試みを認識するためのユーザートレーニングを提供する必要があります。
対応
侵害が検出された場合、影響を受けたエンドポイントを隔離し、侵害された資格情報を無効にし、不正なRMMエージェントを削除し、C2インフラストラクチャを特定するためのフォレンジック分析を実施し、法執行機関と保険会社に通知します。荷物掲示板アカウントのセキュリティを確認し、強化し、不正な貨物投稿を監視します。
