スマート冷蔵庫になりすまし、CTVのトラフィックを改ざんする詐欺グループ

DVフラウドラボは最近、不正行為を隠すためにスマート冷蔵庫やスマートウォッチなどのIoT（Internet of Things）デバイスになりすましたスキーム「LeoTerra」の新しい変種を発見しました。DVは、LeoTerraの最新亜種により、保護されていない広告主が2022年上半期に最大1000万ドルの損失を被ったと推定しています。この詐欺スキームの仕組み、DVがそれを検知できた理由、そしてDVが長年にわたってこのスキームや類似のスキームからどのようにクライアントを保護してきたかについて、詳しくはこちらをご覧ください。
