"Cyberattack" is too broad a terms to form a reasoned opinion about this. If the attack was an attempt to take over armed drones, or disable the Iron dome, or something of that sort, then it really should be thought of as an attempt at a kinetic attack. If it was a more "traditional" cyber attack then this would be a disproportionate escalation that sets the stage for cyber conflicts to escalate to real wars with real bombs. Of course, in this particular case, it is hard to call Isreal's attack much of an escalation, as they are already lobbing bombs at each other. I would much more concerned if Isreal bombed, say, Iran for a cyber attack, as that would represent a very real kinetic escalation.
