I'm a world-wide security evangelist, meaning I write and speak about hackers, cryptography, fraud, malware and all that interesting stuff.

I write a bi-weekly column at SecurityWeek, and have had the good fortune to write for DarkReading and SC Magazine and Network World.

I'm a fly-fisherman, a baseball fan and a craft beer enthusiast.

Spring 2018 Password Attacks

This is basically me channelling a series of emails with Marc LeBeau. He gave me permission to submit it as an article and I really like the way it came out. BTW can you guess the racy password that my editors didn't want me to write about?

Australian CyberSecurity Magazine - IoT, DDoS and Threat Modeling

Here's an audio interview I did at the Australian CyberSecurity Conference at Canberra in April of 2018. About 10 minutes. A little background noise, because we just did it in a quietish corner of the conference.

44% of Telnet Scans come from China

IT Pro wrote an article based on our media briefing in HK. I don't actually know what it says, but I think it's something like "44% of Telnet scans (or attacks) coming from China". Google Translate doesn't work for cantonese?
