hey, i couldn't find an appropriate answer on the web so i thought i would ask ya'll. a few days ago i did a finger on my solaris 7 box and found something that puzzled me

jobrien ???
cdemoss Craig R. Demoss *pts/6 3:13 Mon 16:40 12.105.102.231

my question is do any of ya'll know why user jobrien has the question marks for real name and nothing for pts, date, or location. also jobrien is not a valid user name. have i been hacked or can this sort of thing happen? i checked my syslogs and messages files to see if there was any unusual activity, and there wasn't. any help would be appreciated

thanks,
