For 19 years, GPS satellites have secretly broadcast a “numbers station” in their public signals. We decoded 12M messages: a 2011 flash where 31 of 32 satellites flipped in hours, “ghost” substrings repeating years apart, and a “TEXT” prefix spreading now. https://lsc-pagepro.mydigitalpublication.com/publication/?i=865273&p=62&view=issueViewer

@elithebearded Sorry, it's basically a print publication, and the online format represents that.

@sjmurdoch very interesting article. But what's the security benefit of rekeying via public broadcast channel? A single key compromise enables the attacker to keep receiving new keys at home directly, doesn't it?
