Late last year, hackers breached Target’s data security and stole information from millions of credit cards. Brian Krebs, who writes about cybercrime and computer security for his blog, Krebs on Security, broke the story. A few days later, he broke the story of a credit card breach at Neiman Marcus.
Krebs spends time in the dark areas of the Internet, where hackers steal data off credit cards and sell the information in online underground stores.
“There are some very bad people and I think it’s never a good idea to dismiss your personal security and safety and that of your family — particularly when you’re dealing with what I would consider sociopaths,” Krebs tells Fresh Air’s Terry Gross.
To do his work, Krebs has learned computer code, the Russian language and how to get onto black market websites and cybercrime networks. And cybercriminals who don’t appreciate his work have found creative and frightening ways to harass him, including calling in a fake hostage situation.
