What are these logs? Was I hacked?
Well it is probably a microsoft OneDrive/SkyDrive log due the log has some upload/download options and the name often appears.

for example:
  com.microsoft.authorization.x cached valid token available for    service::ssl.live.com

You maybe logged in that network once and your smartphone rememberd.
Where did you find it?

But hackers usually dont leave logs because that would make the target distrustful.
