Continually subject to malicious attacks (6)

I believe the answer is:

harass

(Other definitions for harass that I've seen before include "Trouble and annoy continually" , "Vex - persecute" , "Molest, annoy" , "Annoy persistently, persecute" , "Continually torment" .)

I've seen this clue in The Times.
