Lloyd’s of London has published market bulletin Y5433 on state-backed cyber-attack wordings. This follows market bulletin Y5381, issued in August 2022, which aimed to support the Lloyd’s market in appropriately managing the systemic risk posed by state-backed cyber-attacks. Since then, the market has made considerable progress towards clarifying the coverage position in respect of state-backed cyber-attacks. Market bulletin Y5433 sets out Lloyd’s updated approach and expectations for the writing of this exposure.
