Do you think it was a man-in-the-middle attack, or could it be simply bad configuration of computers?

Hi,

Having Norton Security for Mac and for Windows on the partitions of my Mac, I can nowadays think that the Mac version has no SONAR (including heuristic mode), but its firewall seems to be more accurate.

Connecting legally my computer to the Wi-Fi of an office, I got about 300 warnings in 2 minutes on the Mac partition (although the Windows version of Norton Internet Security did not see anything). (See attachement.)

I kept only this message - not other historical event - but it is the main.

-Do you think it was a man-in-the-middle attack or spy?

(The labels are in french, knowing: when, from, attack's name, application.)
