It seems like we hear about corporate (not to mention consumer) hacks in the news every week. Is this something new, or just a continuation of old patterns and we just happen to be hearing about it more now? In this segment of the a16z Podcast, longtime security investigative reporter Kim Zetter of Wired -- who also wrote Countdown to Zero Day, the definitive account of Stuxnet, the first digital virus that wrought physical destruction (on a nuclear facility) -- breaks down how hacks happen. What's old (like phishing), what's new (like spear-phishing and ransomware)? How are players around the world -- whether for government or economic espionage -- becoming ever more sophisticated, coordinated, and organized? And what can companies do? Zetter shares her observations on how security models have changed -- for example, from defensive to offensive -- to how she susses out the truth when different players communicate about or claim hacks. (Which is one of the reasons that Zetter questions North Korea's role in the Sony hack...)

The potential to turn messaging into a platform is driving much of the excitement in mobile, says a16z’s Benedict Evans. It's a platform through which other apps flow (and where all the users get aggregated). Take for example Facebook's recent announcements, which put it right where it wants to be on the mobile phone -- in control. So what’s next in messaging? And what will Apple, Google, and other players like WeChat have to say about it? The views expressed here are those of the individual AH Capital Management, L.L.C.
