It would be super useful to have Claude ingest a paper and try to reproduce (some of) the results. I tried it once and it completely failed to get the point.

We found a new vulnerability in TLS. It's a variant of the ALPACA attack that bypasses current countermeasures. Relativly low impact - but great insight! Check it out: opossum-attack.com
