So if the phone compromised the air-gapped machine on the other side of the room (which the article concludes is unlikely) the attacker has 1/6 of the key.
Do you have any evidence, even circumstantial, that the other 5 stations were compromised? Or do you have some other reason to believe the entirety of Zcash is "likely compromised"?
Is prudence not prudent in matters such as these?
