Interested as well, smashing security is one i have not heard of, adding it to my list!
Hacking
This is the community for all things hacking and cybersecurity, try keeping it legal. That said I don't take any responsibility for anything that happens/comes from this group but I will try being the best mod that I can to prevent anything from happening.
It's pretty great. It's a discussion style podcast and the hosts and guests are pretty funny and have great banter. They each usually have a different perspective on the topic too so you get some good views on the topic.
Here are some of the podcast I listen ... Cyberwire daily, Hacking Humans, Naked Security, Day0, The Social Engineer Podcast, The Application Security Podcast, Critical Thinking, Hacker Public Radio, Spycast, Enterprise Linux Security
Modem Mischief popped up on my feed recently when I was looking for a podcast about Stuxnet. It's pretty decent, its dramatizations can be a bit much at times, but it seems thoroughly researched and it has a lot of cool stories about early 90s civilian hacking, which are my favorite. The pentest stories from Darknet Diaries got pretty old.
I recommend the opensource security podcast.
