I came here looking for one too. All they offer is the CSV that powers a Neo4J graph, not a link to the 1.4TB of files (which is what I want to ingest)
>On November 5, 2017, ICIJ added data from some politicians featured in the Paradise Papers investigation. ICIJ will be releasing the full structured data connected to this investigation in the coming weeks.
If I remember correctly, none of the icij releases have ever been made public. Their assumption is that countries should change their laws if they want to access such files. (Also it is probably better like this to protect the sources)
