Cyber Privateers: The Return of the Hack-Back Debate

This piece surveys the renewed debate over offensive cyber "hack back," citing reports of Google Threat Intelligence Group forming a "disruption unit" and a U.S. bill (H.R. 4988) invoking letters of marque to authorize private-sector retaliation, alongside policy analyses warning about legality, attribution, escalation, and collateral damage. It includes mixed industry reactions and argues that while U.S. government agencies already conduct authorized offensive operations, broad private-sector hack back is inadvisable and should, if pursued at all, be restricted to a small number of highly trained, approved companies.
