SPIT (user) on my MacBook Air

Can someone explain this...showed up in my logs, MacBook AIr (Yosemite). No one else uses this computer, however, I think someone did on Sept. 2. Is this normal or is someone with user name SPIT

hacking? Never saw this before Sept 3 and all log files for Sept. 2 were gone when I checked for them on Sept. 4. PLEASE HELP
