Successful Hack of Time-Triggered Ethernet
Time-triggered Ethernet (TTE) is used in spacecraft, basically to use the same hardware to process traffic with different timing and criticality. Researchers have defeated it:
On Tuesday, researchers published findings that, for the first time, break TTE’s isolation guarantees. The result is PCspooF, an attack that allows a single non-critical device connected to a single plane to disrupt synchronization and communication between TTE devices on all planes. The attack works by exploiting a vulnerability in the TTE protocol. The work was completed by researchers at the University of Michigan, the University of Pennsylvania, and NASA’s Johnson Space Center…
