An aggrieved sender of unsolicited email -- that is to say spam -- is reportedly behind a widespread cyberattack that's going on even now. Internet users around the world have been noticing sluggish responses from even sophisticated computer systems such as Netflix.

It all started when Spamhaus, a company that fights email spam, blocked Cyberbunker, a company that reportedly makes money from spamming. Now Cyberbunker is fighting back. The spammer believes that the blocking of its servers is an abuse of authority by Spamhaus.

Alex Cox, a lead security researcher at the firm RSA, joins Marketplace Tech host David Brancaccio to discuss the extent of the attack and when it will likely come to an end.
