that's the slowest method of exfiltration (as mentioned in your quote). I looked at USBee (one of the other methods mentioned by the article) and found [0] which says:
> USBee transmits data at about 80 bytes per second, fast enough to pilfer a 4096-bit decryption key in less than 10 seconds.
These methods are only going to be deployed for very high value data, so it's likely you would want a method of flagging a certain machine as infected (which something like AiR-ViBeR would be very suitable for) so you can use something more high frequency (but maybe more likely to be detected) to get larger amounts of data off the drive.
