At least from CNN's story, it seems unclear whether this was an attack by a known pro-Iran group, with an "in retaliation for killing schoolgirls" tagline. Or an attack by some unknown group(s), with such a tagline.
Given how many hacking groups don't like the US, the latter would tell us almost nothing about the attackers' actual identities and objectives.
