Brian Krebs’s widely read cybersecurity blog, Krebs on Security, covers a particularly dark corner of the Internet: profit-seeking cybercriminals who make billions off pharmaceutical sales, malware, spam, frauds, and heists like the recent ones that Krebs was first to uncover at Adobe, Target, and Neiman Marcus.
Krebs — a former reporter at The Washington Post, he taught himself to read Russian and blogs with a shotgun by his side — is so entrenched in the digital underground that he is on a first-name basis with major Russian cybercriminals. Many call him regularly, leak him documents about their rivals, and try to bribe and threaten him to keep their names and dealings off his blog. But few have done more to shed light on the digital underground than Krebs.
