Re: Hackers v crackers v DDoSers
These uses of "cracker" do not seem to be noted in either the OED or Merriam-Webster - they say a "cracker" is A contemptuous name given in southern States of N. America to the ‘poor whites’; whence, familiarly, to the native whites of Georgia and Florida. Quotations claim various etymologies: "a name they have got from being great boasters", or "supposed to have been suggested by their cracking whips over oxen or mules in taking their cotton to the market."
