DMA attacks go back a long way and affect a lot of connection types. From wikipedia: FireWire, CardBus, ExpressCard, Thunderbolt, PCI, and PCI Express.

The good part is that it requires physical access of some sort. The bad part is that it’s now comparatively easy to hide everything, including wi-fi data egress, in a normal looking cable.

A good rule of thumb is to not buy or use odd brand cables or cards, or to buy from places like amazon that are careless about mixing counterfeits in with genuine stuff.
