    How to read a case

    • Each attack has one category, chosen by its main loss. Causes, actor and loss scenarios are tags that can be combined.
    • The attribution level separates what an authority or the victim has confirmed, what a group has claimed and what researchers or journalists only suspect.
    • The policy block describes how a standard market cyber policy would respond, not the victim's contract. When the actual cover is public, it is shown separately with its source.
    • Every fact comes from an open source. What is not known is written as not known.

    Which attacks enter the registry

    • An attack enters if the victim or an authority confirmed it, or if at least two reliable sources reported it.
    • It must have at least one material effect: an operational outage, data of at least 100,000 people, a declared cost of at least 1 million, a public or critical victim, or a mandatory disclosure such as an SEC filing.
    • Claims published by ransomware groups alone are not enough.
