as a 23andMe user with a high percentage of Ashkenazi genes I expected my data to be in the leak but it wasn't so it's probably not all of the Ashkenazi data
(as to how I verified: the file is still available on the leak site)
These are the headers:
profile_id; account_id; first_name; last_name; sex; birth_year; has_health; ydna; mdna; current_location; regions; subregions; population_ids
First entry is Elon;Musk;Male;1971;...But yes, for EM it said "Ashkenazi;Balkan;British Irish" - no percentages in there - and I believe 23andme has confirmed the authenticity of the data.
