📣THREAD: It’s surprising to me that so many people were surprised to learn that Signal runs partly on AWS (something we can do because we use encryption to make sure no one but you–not AWS, not Signal, not anyone–can access your comms).

It’s also concerning. 1/
PSA: we're aware that Signal is down for some people. This appears to be related to a major AWS outage. Stand by.

I am doing a survey of supply chain attacks, and it's annoying how 95% of the analysis is on payloads vs. compromise vectors.

Yes, you are a very smart reverser and that's a very clever payload. Yes, rolling out phishing-resistant auth is a slog. No, this is not how we make progress.

This is a very important article and @evacide.bsky.social brings up a very great point. Many relationships are one sided when it comes to technical knowledge.

Who set up the home thermostat? the wifi? the IOT garage door?

Show me an IOT thing, I can come up with how it can be a vector for abuse.
I talked to 404 Media about devices for tracking and spying on your partner being sold on TikTok. This is not stalkerware, but these are devices for tech-enabled abuse and I think we should be talking about tech-enabled abuse more broadly.

You really should read this article on how criminal groups routinely bypass EDR. This isn’t state stuff. I see it all the time, and have for a while. The sad truth is EDR is one rung in defense in depth and it surviving tampering is a perpetual cat mouse game. www.theregister.com/2025/08/14/e...

Dolly Parton has sent my daughter a new book every month for years as she does for thousands of children. She help fund the development of the Covid vaccine. She’s not a billionaire. I think as non wealthy people it’s hard to even imagine how much billionaires *could* be doing with their money.

I’m playing a CTF with my bestie, as one does, and she pointed out that challenges that use generative AI violate the cardinal rule of CTFs, which is that everything that is in there is there because someone put it there on purpose

As a longtime player and author, that is genuinely really upsetting

If you send me a 3000 word essay based on a 20 word prompt you are transferring information in an incredibly inefficient way. I'm going to have no idea what you actually wanted to convey. Just send me the prompt. I promise the outcome will be better.
