    Abstract: A method includes capturing first data associated with a first packet flow originating from a first host using a first capture agent deployed at the first host to yield first flow data, capturing second data associated with a second packet flow originating from the first host from a second capture agent deployed on a second host to yield second flow data and comparing the first flow data and the second flow data to yield a difference. When the difference is above a threshold value, the method includes determining that the second packet flow was transmitted by a component that bypassed an operating stack of the first host or a packet capture agent at the device to yield a determination, detecting that hidden network traffic exists, and predicting a malware issue with the first host based on the determination.

    Abstract translation: 一种方法包括使用部署在第一主机处的第一捕获代理捕获与来自第一主机的第一分组流相关联的第一数据,以产生第一流数据,从第二主捕获与第一主机起源的第二分组流相关联的第二数据 部署在第二主机上的捕获代理产生第二流数据并比较第一流数据和第二流数据以产生差异。 当所述差异高于阈值时,所述方法包括确定所述第二分组流由绕过所述设备的所述第一主机或分组捕获代理的操作堆栈的组件发送以产生确定,检测所述隐藏网络流量 存在并且基于该确定来预测与第一主机的恶意软件问题。
