谷歌昨日從 Chrome 網上應用店中刪除了 32 個惡意擴展程序，這些擴展程序可能會改變搜索結果並推送垃圾郵件或不需要的廣告。總的來說，它們的下載量為 7500 萬。

這些擴展具有合法功能，可以讓用戶不知道混淆代碼中用於傳遞有效負載的惡意行為。

網路安全研究員 Wladimir Palant 分析了 Chrome 網上應用店提供的 PDF 工具箱擴展（200 萬次下載），發現它包含偽裝成合法擴展 API 包裝器的代碼。

安裝量最大的幾個惡意插件：

• Youtube 的 Autoskip------900 萬活躍用戶

• Soundboost------690 萬活躍用戶

• Crystal Ad block------680萬活躍用戶

• Brisk VPN -- 560 萬活躍用戶

• 剪貼板助手------350 萬活躍用戶

• Maxi Refresher------350 萬活躍用戶

• 其他帶後面的瀏覽器插件的ID
