#11 - Hacking Hackers and their Hacks

#11 - Hacking Hackers and their Hacks

May 23, 2018

Is it cast aside teenage wunderkinds who can seemingly dissect all things computer with the crack of a laptop to create designer chaos?  They are portrayed smoking cigarettes, roller blading and always have media savvy branding!  Too cool!

Any time a major breach is announced, the media conjures up their classic image of this hooded jedi-like figure in a dimly lit room with 0s and 1s swirling about. Film and TV has done a superb job of portraying our favourite computer hacker as the stereotyped quirky yet heavily crafted indie kid who wields the required dexterity to power-type at a moments notice, anywhere on the planet and inject themselves straight into anything from corporate servers, to traffic light control systems to Dinosaur based fun parks. It usually involves some superb visualisations of neon landscapes and swirling equations.

In the episode I unpack hacking and what it really is, with a few notable examples from the past few years.   

Warning! I may debunk Hollywood's sexy portrayal and expose hacking for what it really is... good ol' fashioned elbow grease.

The shownotes for the episode are here.

#10 - Machine Learning ( Real World Applications )

#10 - Machine Learning ( Real World Applications )

May 9, 2018

Machine Learning

I’ve heard the phrase Machine Learning banging around the media more intensely over the past few years and you know what that means… I’m not happy until I know what is really means.

TO THE BAT-MOWER!

My first conjured image is of course a lawn mower in a classroom trying to fumble its way through the shakespearean sonnet.

It seems I wasn’t far off! Ok I was pretty far off. But there is a smart lawn mower that learns how to cut you lawn which is in fact machine learning. It’s the word machine which I find distracting. We’re not accustomed to speaking of computers as machines or machines as computers although the latter is quickly becoming so and hence the phrase.

A few podcasts ago we discussed Self-Driving Cars and machine learning is definitely at the core of their success. We have all driven cars and would unanimously agree that no two routes are the same even if you’re driving the same route every day. There is always some element of surprise. These cars would not exist if not for some very clever learning algorithms which prioritise success paths over failures in order to adapt their reactions and even their default behaviour to new situations. Just like us human learners.

What about other non-driving based applications? The mower is essentially a tiny little self-driving car that works out your lawns shape and the best route while having the luxury of not having to contend with human driven lawn mowers, drinking and just mowing all over the place.

Machine learning and AI (Artifical Intelligence) are peanut butter and chocolate, ham and cheese, bacon and…. everything. What’s the point of learning if you aren’t going to use what you have learned? I could dive deep into the inner workings of machine learning algorithms but that would be a serious snoozer to the non-enthusiast and as complex and fasinating as it is, it’s more fun to try to derive the gist of what it all means by looking at the applications because without application there is no learning.

Are we surrounded by learning machines who will eventually take over the world? Yes!
But how? Let’s have a crack at a top 5! 

Check out the podcast for the list.

#7 - Part 1 - Browse This!  (Browser Security)

#7 - Part 1 - Browse This! (Browser Security)

March 7, 2018

Let me go back to the beginning. 1990!

Shortly after the earth cooled and life began,  Sir Tim Berners-Lee just decided to invent the world wide web.  This was approximately 1990 give or take any prior research and general acceptance of the idea. He also put together the first browser confusingly and yet inspirationally called "WorldWideWeb".

Well now you know how that all started and why it's called what it is. For those of you who were toddlers or perhaps not even born yet a world without the web sounds like a time when everything was in black and white, lit by open flame, the notion of evolution was exciting and new and tablets were made from stone.

Since then things have evolved. The browser which began as a simple visual interpretation of a "markup" language used to create a textual representation of visual elements is now a dangerously functional run-time environment potentially comparable to our host operating system, more than you might expect.

#2 - The Ransomware Show (2017)

#2 - The Ransomware Show (2017)

November 14, 2017

This is one of those subjects that has struck everyone from the techno security guru to the average person who might simply be trying to do their job.  Ransomware brands such as Goldeneye, Petya (and its counterpart NotPetya), Cryptolocker, CryptoWall, Locky, WannaCry and very recently, Bad Rabbit (to name only a few) have been making headlines across the globe.

I’ll start by taking a quick step back and just define Ransomware before I discuss how it tricks us into letting it in the door. I'll then take you through the stages of it's existence and finally what we can do to be better in the face of quickly advancing and mutating Ransomware attacks.

2017 was the year of the Ransomware... or is it?  2018 is just around the corner so only time will tell.

Check out the full blog article based on this podcast on the Codifyre website.
