PSA: tips to protect yourself from scams on Signal.

Every major comms platform has to contend w phishing, impersonation, & scams. Sadly.

Signal is major, and as we've grown we've heard about more of these attacks--scammy people pretending to be something or someone to trick and abuse others. 1/

Great expose on the status of attack capabilities at Cellebrite, the defense company used by homeland security agents to crack your phones both at the U.S. border, airports, and interior.👇
New from 404 Media: someone managed to get into a Microsoft Teams call with phone hackers Cellebrite, who then detailed some of the company's hacking capabilities against Google Pixel phones. Also its capabilities against GrapheneOS, security-focused devices www.404media.co/someone-snuc...

When @wired.com made FOIA-based stories free, subscriptions went up.

When @404media.co published public records reporting without a paywall, new sources came forward.

We spoke to both about why dropping paywalls like this is good for journalism — and for business.
Wired and 404 Media make FOIA reporting free. Other news outlets should too
We spoke to Katie Drummond of Wired, Joseph Cox of 404 Media, and Lauren Harper of Freedom of the Press Foundation about the case for unpaywalling public records-based reporting

This thread does a better job of capturing why the cloud isn’t merely “renting a bunch of servers” than anything else I’ve seen recently.
📣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.

Good thread from @signal.org CEO, @meredithmeredith.bsky.social underscoring our critical dependencies on a few key orgs, and an increasing challenge in organizational and national resilience. We have a lot of work to do. cc @gate15.bsky.social
In short, the problem here is not that Signal ‘chose’ to run on AWS. The problem is the concentration of power in the infrastructure space that means there isn’t really another choice: the entire stack, practically speaking, is owned by 3-4 players. 11/

Excellent thread that I kinda had been waiting for.

The question isn’t "why does Signal use AWS?" It’s to look at the infrastructural requirements of any global, real-time, mass comms platform and ask how it is that we got to a place where there’s no realistic alternative to AWS and the other hyperscalers. 3/

Pray, Mr. Altman, if you put into the machine correct figures, will the right answers come out?

I wish more people knew that there’s virtually no way to prove media or text is AI-generated unless you created it yourself. “AI detectors” aren’t proof. Among other glaring issues, this makes it more difficult for journalists to report on media being AI-generated even when it seems obvious

I'm the president of Signal. I love dance music in the mornings, night yoga, and acting like a tourist — here's a day in my life.
