Cryptojacking, and Farewell for Now!

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 that remains completely hidden from the target and can infect millions of computers with cryptojacking

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 course... Either way, curiosity can be a powerful tool, even at a young age. To the point that it may help

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.

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.

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 but now is not the appropriate time. The point is, hackers have been portrayed as the same character

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, and your actual heart rate by 9 am.
