Uc app hacked

Today I recieved an email saying changes were mad to my uc app. Does this mean I got hacked? I am so scared what should I do? Can the UCs find the hacker that hacked my account or will I just be rejected from all schools? :(((

Contact the UC’s by phone, immediately.

They will ask you personal information about you that only you would know. They may have you submit some items by email.
If you reside near a UC, you may want to walk into admissions and let them know. They will put you in contact with their IT department.

Do you think they will find the hacker?

Lol.
