Amid a massive exchange of rocket fire and airstrikes between Israel and both Hamas and Islamic Jihad this weekend, Hamas attempted a cyber operation against an unspecified civilian target in Israel. The operation failed, and in its aftermath the Israel Defense Forces carried out an airstrike that destroyed the building housing Hamas’s cyber capability. Some observers are citing the incident as an important—and perhaps dangerous—precedent. Others are questioning the legality of the strike itself. Robert Chesney writes in Lawfare that both these views are misplaced.
