VIDEO: What the Katy Perry hack teaches us about computer security

Katy Perry’s Twitter account was hacked.

Which is a problem, because almost 90 million people follow Katy Perry on Twitter, making the pop singer the most followed person in the world.

How do we know Katy was hacked?

She said something nice about Taylor Swift.

It could have been worse. Imagine if the hacker had tweeted a malicious link instead of a juvenile message to Perry’s arch-rival.

Watch my video about the lesson all Twitter users should learn from Katy’s account being compromised, and enable Login Verification if you haven’t already done so.

Stay safe folks!
