The success of crypto inspired dozens of other cryptocurrencies like Ethereum, Tether, and Dogecoin. Today, people worldwide use cryptocurrencies to buy things, sell things, and make investments. One thing is certain; digital currencies are here to stay, no matter how many times you have to explain what a bitcoin is. Unfortunately, it also created the world of cryptojacking, a form of cybercrime t...

Ransomware attacks have never been so successful. The returns from these attacks are soaring and only becoming easier to conduct. In chapter two of the Microsoft Digital Defense Report, the growing threat of cybercrime is covered in great detail.

Everything is exciting and new when you're a kid, and curiosity inspires many of us to branch out and try new things. For some, that means drawing from our imagination or trying all kinds of sports. And for others it means spending days at the library, checking out books on modem communications, and eventually hacking into the local dial-up community service. That's just a random example, of cours...

Disinformation refers to the calculated use of false information to influence others and has been a steadily growing form of information warfare. Unfortunately, disinformation is everywhere these days, often hidden in plain sight. Criminals will also adapt and take advantage of technologies, such as AI and deepfakes, to increase the effectiveness of disinformation campaigns. Of course, there are w...

We are back, covering more of the 2021 Microsoft Digital Defense Report, and this time we’re taking a deep dive into chapter five on Hybrid Workforce Security and Zero Trust. Zero Trust means precisely what it sounds like, never assuming any device or identity is secure; it's like having major trust issues, but in a professional way. With most businesses moving to remote work because of the pandem...

The way most people operate online these days, what would you even consider private anymore? We are so quick to share details about our job, home, friends, and family without even thinking about how much personal info we're giving away. Privacy and user agreements are a part of almost everyone's life at this point, and what do you know about them? For the most part, we often see a user agreement p...

The newfound popularity of the internet in the nineties spurned an obsession with hacking. Unfortunately, most movies believed that it wasn't possible to show real hacking and still be entertaining; hence all the awkward video game graphics and characters living in sketchy basements regularly yelling out, "We're in!" while pounding on their keyboards. I'd also like to address their outfit choices...

We've read the report front to back and have decided to cover some of it today on the podcast, but you'll still need to read all 134 pages yourself if you truly want...

What would you say is the most personal possession that you own? Most would say their cell phone... unless you still have a few journals from high school. And if you do, this is your reminder that it might be time to let those go. It's become increasingly apparent lately how much info our phones collect from us, from the first app you check in the morning after waking up, recent calendar entries,...

You're back home celebrating the holidays with friends and family, sharing stories, catching up, and discussing your plans for the year ahead.

Oh yeah, he's also going to cut you in on a sweet deal he has going on...

Do you have a data science or engineering background? If so, you're in luck. If not, you're also in luck because today's guest found a way to make a few complex subjects understandable for everyone. The first of many topics... Fuzzy hashing. It might sound like an adorable, adventurous Muppet character, but I promise you the reason behind it is not cute at all. The short explanation is "fighting c...

Unfortunately, it's a robot that somehow knows your name and is asking for your social securit...
