Memory isn't being exposed, just the fact that something is touching memory in a certain place. That ssh login keystrokes leak via side channels is a long standing flaw in ssh. Memory access patterns can already be inferred from network response latency on any processor, nothing about that is new or surprising.
- cma 7y agoThis doesn't give more timing precision than previous techniques?
- angry_octet 7y agoIt is a super accurate way of timing packet receipt. For keystrokes sent across a WAN that wouldn't normally help you. But this really isn't about ssh, which is just used as a cute demo of the power of traffic analysis and side channels; this is about remote access to local side channels in the memory system.
