Myself and Steve Townsley have been working on a podcast where we talk about fun security topics from both an offensive and defensive perspective: purpleteamdialogues.podbean.… We've already done a couple of episodes talking about the Crowdstrike 2024 report and Phineas Phisher. Enjoy!

CTI in a nutshell.
every time i am forced to take a mandatory security training, i am being reminded of how @thegrugq was right about how people give names to concepts they do not understand tricking themselves into thinking they do. youtu.be/wP2J9aYM6Oo

At the risk of sounding overly philosophical, the more someone has already made their mind up about themselves, other people and the world around them, the worse they will be at security.

Kicking it old school! Great story...
Christmas Lecturer John Ambrose Fleming (#BOTD in 1849) was involved in the first public display of hacking, which took place here at the Ri as early as 1903. Read the story of how his demonstration of long-range wireless communications was taken over. rigb.org/blog/2014/november/…

A lot of you might be too young to remember this, but back in the day memory corruption was this big security problem with quite a lot of our software. Anyway we learned to program more carefully and it sorted itself out

My students @maxzks and Tushar Jois spent most of the summer going through every piece of public documentation, forensics report, and legal document we could find to figure out how police were “breaking phone encryption”. 1/

If you work in, or are interested in, offense, I highly recommend reading this article!

A lot of this "expert analysis" has been of the form: "Many locks can be easily picked. If someone picks the lock on your house, they could break in and murder you and your entire family in the middle of the night. Therefore, you and your entire family have been murdered."
