In more detail (from Wikipedia: https://en.wikipedia.org/wiki/Distributed_Denial_of_Secrets):

Distributed Denial of Secrets, abbreviated DDoSecrets, is a non-profit whistleblower site founded in 2018 for news leaks. The site is a frequent source for other news outlets and has worked on investigations including Cyprus Confidential with other media organizations. In December 2023, the organization said it had published over 100 million files from 59 countries.

Sometimes referred to as a successor to WikiLeaks, it came to international attention for its June 2020 publication of internal police documents, known as BlueLeaks. The group has also published data on Russian oligarchs, fascist groups, shell companies, tax havens and banking in the Cayman Islands, as well as data scraped from Parler in January 2021 and from the February 2021 Gab leak. The group is also known for publishing emails from military officials, City Hall in Chicago and the Washington D.C. Metropolitan Police Department.

The site's leaks have resulted in or contributed to multiple government investigations, including the second impeachment of President Donald J. Trump. During the Russo-Ukrainian War, they were considered one of the best public repositories of all the Russian files leaked since the invasion began.
