Cyberwarfare ended up quite low on the escalation ladder, but I think that's partly because the most extreme cases (i.e. where you're actually trying to destroy or incapacitate) like U.S./Israel attacks on Iranian nuclear infrastructure or Russian attacks on Eastern Europe only happen between countries that at borderline hostility anyway. Most cyberattacks are just espionage but with computers, which happens even at peacetime between allies.
