When you know who someone is, have followed their patterns, and know who their friends are, you can get them to respond to phishing messages.
At least, that was the theory when DFO lured an orca away from the harbour where he had taken up residence. (And now someone is going to take issue with "residence," since he was not from one of the resident pods, but was a transient.)
(And, yes, I know that orcas are delphinidae and therefore not true whales ...)
(Oh, you want even more links to security? Well, there is life safety, since transients feed on mammals, and that's what we are ...)
