Is there any way to tell what NSURLSESSIOND is doing?

NSURLSESSIOND has become the primary means that all applications use for network communications. The problem with that is there isn't a way to track down which applications are transferring data. I see multiple MB/sec of upload occurring when I haven't requested any uploading. Not only is it tearing through my bandwidth (not everyone has unlimited transfer), but I'm VERY concerned for security reasons.

I'm monitoring and seeing upwards of 5 MB/sec literally all night....hundreds of gigabytes of data being uploaded.
