Rucknium1 has published all of the HackerOne2 and CCS (M1-M2)3 document and code submissions related to their Optimal Static Parametric Estimation of Arbitrary Distributions (OSPEAD)4 project, after 3+ years of research:

The OSPEAD documents and code are being publicly released now because there is now an implementable solution to the problems I raised in my original HackerOne submission. Public release will allow greater review and scrutiny of the proposed OSPEAD techniques. [..] The documents total well over 100 pages.

Preliminary estimates point at an average attack success probability of 23.5% since the August 2022 hard fork, which corresponds to an effective ring size of only 4.2:

The OSPEAD techniques suggest a new decoy distribution, which would reduce the average attack success probability to 7.6 percent, corresponding to an effective ring size of 13.2.

Visit the project’s repository on Github for the associated code, documents list and reading guide5.

This is an ongoing story and the report will be updated when new information is available.
