Wouldn't moving away from copper (or at least using shielded wiring) also provide significant protection? The attack relies on electromagnetic interference being able to obfuscate a packet header.
- sohkamyung 4y agoYes, that's one of the mitigations mentioned in the article: > Kasikci: We identified several different mitigations that are effective against our attack. In general, they fit into two basic categories. The first category is to block a device from conducting electromagnetic interference into your TTE switch. [...] Another option is to make it so that, even if the attacker does inject electromagnetic interference into the switch and causes this malicious protocol control frame (PCF) to go out, the system won’t be affected by it. You can do this by altering the topology of your network, so that the spoofed PCFs never follow the same path as legitimate PCFs.
