This horse probably knew something about bases, do you think she knew base64.... cause I certainly don't. Note the attachment directly decodes to the flag, nothing extra

Where did all my pixels go 😦 anyways go find the name of the horse circled in red and the most recent common ancestor of the 2 horses in the 2 images, submit the flag as all lowercase with words separated by underscore, for example if you think the horse circled in red is T.M. Opera O and the most recent common ancestor is Northern Dancer submit ictf{t.m._opera_o_northern_dancer}

The horse gatcha has infected the ictf board, can you find out who this horse is? to get the flag combine the name of the horse, the date on which they achieved their first win, the date of their final race, and the winner of their final race, and enclose that in the ictf format. The flag will be all lowercase, separate words and components by underscore, use the day-month-year format, for example if you believe the horse is gold ship, submit

ictf{gold_ship_09-07-2011_27-12-2015_gold_actor}
