Coverage description

An Insurance Services Office (ISO) standard form. It pays the costs to find out whether a cyber incident has affected a scheduled owned private passenger auto, light truck or medium truck, and to investigate, restore its computer system and data, tow it and provide temporary transportation, up to an aggregate limit. Ransom payments can be added, and it provides no liability or physical damage coverage.

    • Coverage now responds to a cyber incident as defined in the coverage form, replacing the endorsement's own definition of an auto hacking incident (malicious code or a denial of service attack).

      “"Auto hacking incident" means any”

      09 27

  2. 01 24 edition

    Jan 2024, compared with 09 22
    • The incident must now occur to a covered auto located within the coverage territory and be discovered during the policy period or the 30 days after, instead of being discovered within the coverage territory.

      09 22

      “is "discovered" within the coverage territory”

      01 24
