Krebs on Security

Krebs on Security is Brian Krebs's investigative reporting on cybercrime, data breaches, and digital risk, written by a former Washington Post reporter who has spent years tracking the criminal underground behind ransomware gangs and carding forums. It's one of the most cited sources in security journalism, frequently breaking news on breaches before companies disclose them publicly.

Posts read like investigative journalism rather than vendor blog content: sourced, detailed, often uncomfortable for the companies involved. It's read heavily by security professionals, journalists, and anyone who wants to understand the human networks behind major breaches, not just the technical vulnerabilities.
