Official document

In re Yahoo! Inc. Customer Data Sec. Breach Litig. — U.S. District Court, Northern District of California, MDL No. 16-md-02752-LHK
March 8, 2018 (reported at 313 F. Supp. 3d 1113)

What the opinion does (high level)

The analysis is a key MDL reference for how courts evaluate risk of harm, mitigation costs, and related theories when large-scale account data is exposed.
