Hackers are stealing data today so quantum computers can crack it in a decade

What a tasteful reference on HN. Love that book.

That said it is slightly harder now most email isnt flying around in clear text just waiting to be scopped up.

Others could be more traditional, like a dragnet that infiltrates common applications or exploits, then hunts for IAM credentials or a DB server.

Users checking tokens with public endpoints into repositories is also very common.

Also, the term is post-quantum cryptography. I don't think it can be declared quantum-safe or quantum-proof just yet.

They're probably targeting communications, like those diplomatic cables Manning leaked. I'd assume top secret "design secrets" aren't transmitted. My understanding of spying is it's typically focused on gleaning information from sources a laymen would consider boring and/or useless. For instance, the NSA worked until 1980 to decrypt certain Soviet messages sent between 1942 and 1945 that re-used one-time pad pages:

Huh? Didn't DES use NSA-provided unexplained magic numbers that many people were highly skeptical of, but actually made it more secure against an attack that was not publicly known?

For attack: custody is never provable in crypto, as in you can prove you own an account but you cant prove nobody else does. so a hacker can use that to their advantage. They can also delay rotation by carefully picking their targets and amounts, as all the victims will be victim blamed and not believed for a very long time so a quantum computer hack could exist for a long time unless a large theft was done. Its tricky because many power users will report unexpected thefts and the rumors will start quickly.
