Attack of the week: Airdrop tracing
blog.cryptographyengineering.com
It’s been a while since I wrote an “attack of the week” post, and the fault for this is entirely mine. I’ve been much too busy writing boring posts about Schnorr signatures!…

The news was already posted here last week, but I found this great technical explanation of the flaw. Long story short: Apple is using bad cryptography. They got alerted by researchers back in 2019 but didn’t fix it.
