Can you provide some details on your binary rewriter to add shadow stack support? Was this a pure software approach, or was it designed to take advantage of the support in new intel microprocessors? Do you have a write up of or can you give a quick overview of your methodology? Is the source code published somewhere?
- jnwatson 6y agoNo, it was proprietary code, and it wasn't for an Intel processor. It was a pure software approach, but the particular (embedded) environment made it harder to attack the shadow stack itself. I had a pretty cool optimization that I don't think anyone's figured out yet. Oh well. That's the downside of software-as-trade-secrets.
