The G7 Cyber Expert Group's 2026 Cross-Border Coordination Exercise concluded on or before 31 July, according to a GOV.UK update1. The group brings member states' authorities together to coordinate response to cyber incidents that cross national borders, and the exercise is its rehearsal of that coordination. No participant list, no scenario description and no findings have been published.
Silence of this kind is ordinary practice for exercises of this type, since the scenario often models attacks on named sectors and publishing it advertises what the participants believe they cannot yet handle. It does leave the record thin. Cross-border work of the operational kind produces visible results when it lands, as Europol-backed Operation Saffron did in May by pulling 33 servers out of First VPN, an anonymisation service ransomware crews used. An operator in one of the sectors a cross-border scenario would cover has no way to learn which coordination failures the exercise surfaced, or whether the arrangements it depends on in a real incident were tested at all.
