Just when you think CVEs cannot get more ridiculous... 🤣

Interesting. I wonder what's the motivation for projects to opt-in to this, and how many did already. Sounds like it would incur prohibitive costs on the company and the bug hunter (explaining technical security bugs to lawyers is orders of magnitude more involved than to security engineers).

I would like this comic I drew in 2017 to stop being relevant pleeeaaaaase
I wake up in the morning.
I sit at my computer.
The internet screams at me that the world is on fire.
I am overwhelmed by the deluge of bad news and faceplant in front of the computer.

Is Telegram really an encrypted messaging app?
This blog is reserved for more serious things, and ordinarily I wouldn’t spend time on questions like the above. But much as I’d like to spend my time writing about exciting topics, som…

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.

To this day I think my demise will be through some npm shenanigans. And it's fair, I deserve it. It should Javascript->RCE.

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!

Pro tip for if you have XSS but you can only use upper case: aem1k.com/transliterat... transliterate.js by @aemkei.bsky.social works great!

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.

Interesting choice! Most, myself included, prefer Blindsight. Both are really good though, still waiting for the grand finale that will likely never come :)

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 :) bsky.app/profile/jame...

Maybe, but that metric is not likely even correlated to 'most commonly exploited'.
