21 CyberSecurity Twitter Accounts You Should Be Following
Whether it’s general cybersecurity news that you’re after, malware research, outbreaks, pentesting or reverse engineering, you’ll find a gamut of experts on Twitter sharing their own and others latest insights. Of the many thousands of accounts that you could follow, we’ve hand-picked 21 that between them will not only cover the full spectrum of cybersecurity issues but also, thanks to the wonders of retweeting, curate the most important tweets of those they follow. Our list has some well-established “celebrities” in the field, but you’ll also discover some new, interesting and influential people here, too.
1. @briankrebs | Brian Krebs
Surprisingly, renowned investigative cybercrime journalist Brian Krebs doesn’t have a technical background in computer security, but turned his attention to the field after his own home network was infected by the Lion worm back in 2001. If you’re looking for in-depth and breaking news on cybercrime and cybersecurity, @briankrebs should be top of your list.
2. @DanielMiessler | Daniel Miessler
