He refused, was let go, and started a site of his own.
Now he has an international reputation. In some cases, cybercriminals—usually based in Eastern Europe—offer him the inside scoop on their competitors. Other times, they target him for some fairly serious "pranks." One day, a SWAT team appeared outside his house; police had received a fake report of a murder. In another case, heroin was sent to Krebs' house; again, someone reported the false crime to police.
