Ransom Ledger only prints what is on the record: a victim’s own statement or filing, a court document, a government notice, or reporting by a named outlet that traced the money. Every line above links to where it came from, and a payment the victim never admitted is marked reported.
Attribution is the hard part. Groups rebrand, rent their software to affiliates and claim attacks they did not carry out. Where a link between an attack and a group rests on a claim, the entry says so.
