Black Hat and Def Con came and went as quickly as it ever does. The week-long pair of back-to-back conferences, referred to as “hacker summer camp,” draws in the security crowd from across the world onto Las Vegas, where startups tout their technologies as hackers and researchers reveal their findings.

This year we saw ordinary-looking charging cables that can hack your computer, we found out that cloud backups are easily exposed, robocall blocking apps aren’t as privacy-focused as you might think, and your corporate VPN and office printer are targets for hackers (and if they fail there they’ll just ship a hardware exploit to your mailroom.) Even students can easily hack their own school systems.
