# xz-backdoor-github
History of commits related to the xz backdoor Discovered On March 29, 2024: CVE-2024-3094.
Currently GitHub has taken down the repos for ToS violations. The purpose of this is to
faciliate security research of how this backdoor was snuck in over the course of 2 years of active contributions
and to search for other possible issues.
For background see: https://www.openwall.com/lists/oss-security/2024/03/29/4

## Datasets
Using ClickHouse's database of all repo events across GitHub ever, I created three datasets
of github events: the suspect users contributions, and one of all events in their shared project repo
that actually hosted the compromised releases.

Datasets are CSV files with a header row and a data type row, following
ClickHouse's [CSVWithNamesAndTypes](https://clickhouse.com/docs/en/interfaces/formats#csvwithnamesandtypes)
Format.
