Hi! This was posted from the Mastodon X11 app on IRIX, SiliconGraphics Octane2!

UPDATE TOO: Storage was saved! (for now)
Thank you everyone!!!!

Thank you so so very much!!!!!!!!!

🚨 🚨 🚨
UPDATE: Cat 🐈‍⬛🛰️ @catbailey went to pay the storage bill to keep it from being auctioned off and they tacked on more money for a total of about $1200 and if that is not paid immediately then the auction will proceed tomorrow.

So Cat needs at least $325 more. Today, before close of business. That is about 45 minutes from now, or 5pm EST, 22:00UTC

It has to be paid today. The manager will be out with the auctioneer early tomorrow morning, out of contact until after the auction.

⚠️⚠️⚠️Cat urgently needs $847.60 to pay for her kid's father's estate in storage before it is auctioned off in two days.

Please help!

It’s not the most technical CISO that survives, but the CISO who’s most adaptable to change.

Randall Munroe's #XKCD comic has the power to make you laugh, to make you think ... and sometimes to make you cry. For the right reasons.

Wishing another fifteen (and many more) to Randall Munroe, his wife (name unknown but it's not Megan), and everyone else. #FuckCancer

I've been playing with Google's Antigravity AI IDE, and have enjoyed it. But it also led to me typing a line that really struck me: "I wonder if I can vibe code a BBS-style door game as a Slackbot".

I think I can, and 1990's me is pretty tickled about the idea.

This is pretty wild. Checkout.com got hacked by a group that claims to be Shiny Hunters again. Checkout said in blog post that it would not be extorted by criminals.

"We will not pay this ransom.

Instead, we are turning this attack into an investment in security for our entire industry. We will be donating the ransom amount to Carnegie Mellon University and the University of Oxford Cyber Security Center to support their research in the fight against cybercrime."

Far too many victim firms just pay up, to get back to business as usual asap. Imagine if a fraction of those victims instead paid into a fund for research that actively disrupts these groups.

“Secure by design” is shifting from vision to standard. I note progress: >50% of apps now pass OWASP Top 10 checks (up from <33% in 2020) and exploitable flaws dropped from 3.6% to 2.6%. But 70% of apps still have major flaws—true success means making security part of every build, not an afterthought. https://www.forbes.com/councils/forbestechcouncil/2025/11/10/advancing-secure-by-design-from-ambition-to-industry-standard/
Advancing Secure By Design From Ambition To Industry Standard

Real victory will come when secure by design isn’t a special initiative but the standard starting point for every project.

I saw social media posts about the new Apple "iPhone Pocket" and just presumed it was a parody post. It's not, and I can't decide if I'm amused, or just feeling old.

This is fantastic research from Wenyi Morty Zhang, Annie Dai, @keeganryan, Dave Levin, @nadiah, and Aaron Schulman:

They created their own $800 satellite receiver, pointed it at the sky, and recovered calls and text messages on T-Mobile’s cellular network, data from airline passengers’ in-flight Wi-Fi browsing, communications to and from critical infrastructure, and US and Mexican military and law enforcement communications—all unencrypted.

Great reporting, too, from @agreenberg and @mattburgess of @WIRED

Satellites Are Leaking the World’s Secrets: Calls, Texts, Military and Corporate Data

With just $800 in basic equipment, researchers found a stunning variety of data—including thousands of T-Mobile users’ calls and texts and even US military communications—sent by satellites unencrypted.
