Intel chipset can be exploited to sniff SSH passwords as they’re typed over the network. In 2011, Intel introduced a feature called Data-Direct I/O (DDIO) its server processors that allowed network cards and other peripherals to connect directly to a CPU’s last-level cache, increasing input/output bandwidth and reducing latency and power consumption.
