This is highly impressive if this was just simply a hack to be able to remotely have pagers blow up. I can't wrap my head around that.
I think it's most likely Israel had intelligence for awhile and sold pagers to Hamas that already had explosives. Also if that's the case, that means they been reading all their messages anyway. They probably knew even more stuff about Oct 7th then initially reported.
Either way this is some wild shyt. Hope this is worth it for them as they just exposed the type of intelligence/technical capabilities they have to the world.
