Good afternoon, and welcome to the end of another week in Infosec.

This week saw a brief respite from the cold, harsh Queensland winter.
In the AUSCERT office we’re definitely looking forward to the warmer months!

Thanks to our members who were able to attend our Melbourne Member meet-up
earlier this week, and anyone who stopped by our booth at the 2018 Security
Exhibition & Conference. We appreciate all the feedback we’ve gotten!

Here are some of the significant news stories from this week:

through. With the launch of Chrome 68, Google now will call out sites with
unencrypted connections as “Not Secure” in the URL bar.”
