Modern 'witches' are called 'extrasenses' or 'mediums' and so on. 'Бабка' is "old-fashioned" term, but modern 'telepaths' can 'improve' credibility by claming that they are 'ведуньи в третьем поколении" and so on.
Also there is proverb 'к бабке не ходи' literally 'you do not need to go to the witch' meaning you do not need the help of foreteller to see the future.
