"The race that stops the nation" is just around the corner in Melbourne as spring carnival hit its peak this cup weekend.

In the U.S. last week, a massive apparent DDoS virtually stopped the nation, taking down site after site. It's just a taste of things to come.

In a statement, the company whose weak default passwords in its devices contributed to the attack, said, "Security issues are a problem facing all mankind." It's enough to sober even the luckiest of punters.

There is no easy solution. We are all in this together. Our actions online are so interconnected that we are only as strong as our weakest link. How do we incentivise organisations and individuals to take ownership of the security? New cybersecurity groups and organisations are being launched almost daily as governments and the private sector attempt to respond.

These are just some of the topics covered in this week's Digest, along with our reliance on mobile technology, the massive data breach in India involving debit cards, the use of CCTV in Hong Kong taxis, AI and much more.
