TIL about Chersterton's Fence fs.blog/chestertons-... - it puts a nice label to an intuition that I find very useful to apply in practice - from refactoring code, through process engineering. Understand first why the mess exists, in that form, before attempting to clean it up and revolutionize.
Chesterton’s Fence: A Lesson in Thinking
A core component of making great decisions is understanding previous decisions. If we don’t understand how we got “here,” we run the risk of making things much worse.

I don't often post about my work but bughunters.google.com/blog/6355265... is actually super cool thing my team is doing. These short term redteams focused on just stealing our passwords were always amazing to highlight how severely broken complex systems are. The internal writeups are so, so fun!

The Leaving Tradition in Google's security team, which could be described as a type of small-scale offensive security exercise, is a great (and fun) example of team culture. Curious? See this blog pos...

There's no such thing as a "9.2" or "9.8" vulnerability. There's more science in Pitchfork's 0.0-10.0 album rating scale than in CVSS. I am completely serious. Pitchfork reviewers actually put their reviews in context with previous reviews by the artist. That's how bad CVSS is: worse than Pitchfork.

Not sure how I missed that, but we now actually have Ken Thompson's C compiler backdoor code from the classic "Reflections on Trusting Trust". An excellent writeup by @swtch.com - research.swtch.com/nih.

Custom lists are super cool! I enjoy reading social posts, but want to make sure I never miss a quality writeup or technique. To achieve this, I'm building a 'high signal web security' list of topic-focused accounts, which you can pin next to 'Following' if you want :)

This hit close to home.
As we incident responders creep into the holidays and wait for our annual December surprise, I can't help thinking about burnout - always a relevant topic! Like most ops topics, I have a lot of thoughts on the matter.
