I presented “NICraft: Malicious NIC Firmware-based Cache Side-channel Attack” at ESORICS 2025.
We show a cache side-channel launched from the NIC itself. We devised new signal amplification (Aging + Domino) to turn small evictions into a clear timing gap. The attack requires no RDMA/DDIO, no kernel/driver mods.
Thank you for attending and for the great discussion!

Hey the new AMD/Xilinx Alveo U45N site is up.
https://xilinx.com/products/boards-and-kits/alveo/u45n.html
No price info yet.

It seems (very) similar to the SN1000 https://xilinx.com/products/boards-and-kits/alveo/sn1000.html.

* 16x 2 GHz ARM Cortex A72.
* XCU26 1M LUT FPGA
* 2xQSFP28 = 2x100G

It supports Vitis Net P4 and open-nic https://github.com/Xilinx/open-nic.

BTW there is a helpful, candid FAQ on open-nic. https://github.com/Xilinx/open-nic/blob/main/FAQ.md
