From Motherboard: As is so often the case, the easiest way into a secure system is by asking someone for the key. This is the same tactic that a teen hacker claims to have used to gain access to CIA chief John Brennan’s personal email. And it’s fairly similar to “spearphising” attacks, where emails with links to download malicious software are sent to specific people inside a network, in the hopes that they’ll open the email, follow the link, and compromise the system. This is reportedly how Russian hackers got into a Pentagon email server, Ukrainian power stations, and even less conspicious targets, like a German steel mill. Even as the Director of National Intelligence warns that the Internet of Things is a major threat, it appears IRL networks of people are at least as vulnerable. Fortunately for companies that want to find the vulnerabilities in their human networks, there’s an app for that.
