There's a "Signal deanonymized" thing going around:
gist.github.com/hackermondev/4

Stay calm. Deep breaths.

👉 while this is a real consideration, the only thing the attacker gets from this is a very rough (kilometers or tens of kilometers radius) location

👉 other communication platforms that use any kind of caching CDN to deliver attachments are just as affected

👉 you almost certainly should continue to use Signal, unless you specifically know that this is a big problem for you.

@rysiek If you're using a VPN, does Cloudflare still serve you content from a node you're physically closest to, or does it do it based on where your VPN is?

@rysiek Thanks Michal. Obviously, this is not great, but I suspect that if your activities are sensitive enough that being placed in an area that large poses a security risk, then I really hope you're already behind a strong vpn. Hopefully Signal and Discord decide it's actually an issue they should deal with, as it sounds like Cloudflare has decided it's not theirs.
