Methodology # How each record was verified Every record in this index was re-read against its own sources in a single audit pass, published as schema version 2.0-audit. The pass kept all 108 takedown and campaign records, opened the source behind each claim, recovered the exact address of the sources it could, corrected what the documents contradicted, and wrote down what it could not resolve. There is no tiered corpus any more. Each record carries the state the audit left it in, and that state is printed at the top of its page. Here is where the 108 records landed. Source linked 55 records Every claim in this entry traces to a source the audit opened and read. Nothing on the record needed changing. Corrected and source linked 44 records Every claim traces to a source the audit opened and read, and the audit changed something on this record. Each edit is listed with the reason for it. Source linked, supplements unresolved 8 records Every claim traces to a source the audit opened and read, but at least one supplementary source carried over from the earlier pass could not be recovered at its exact address. It is named rather than quietly dropped. Excluded after reverification 1 record Re-reading the sources led the audit to decide this does not meet the inclusion rule. It stays published so the decision can be checked, and it is left out of every count on this site. ### What the audit changed The pass made 138 recorded changes across 45 records. Every one of them names the field it touched, the value before, the value after, and the reason. Nothing was changed without a source behind it, and nothing was changed quietly. The whole log is published on the [corrections page](https://takedownindex.org/corrections), and each record links to its own entries in it. ### What the audit could not resolve Of the 176 sources in the corpus, 10 could not be recovered at an exact address. They are still cited, still carry publisher, title and date, and where a replacement document was found it is cited beside them. They were not deleted and no plausible URL was invented for them. Any record leaning on one is marked source linked with unresolved supplements, so you can see it before you cite it. - [Lumma Stealer operators register replacement domains within a day of seizure](https://takedownindex.org/sources/aggregated-security-reporting-lumma-stealer-operators-register-replacement-domai), Aggregated security reporting, May 22, 2025 - [Bundeskriminalamt statement on Operation Deep Sentinel](https://takedownindex.org/sources/bundeskriminalamt-bundeskriminalamt-statement-on-operation-deep-sentinel), Bundeskriminalamt, June 16, 2025 - [Europol statement on the NetWalker action](https://takedownindex.org/sources/europol-europol-statement-on-the-netwalker-action), Europol, January 27, 2021 - [ZeroAccess botnet disruption announcement](https://takedownindex.org/sources/europol-zeroaccess-botnet-disruption-announcement), Europol, December 5, 2013 - [Belgian Federal Prosecutor's Office statement on the Sky ECC action day](https://takedownindex.org/sources/federal-public-prosecutor-s-office-of-belgium-belgian-federal-prosecutor-s-offic), Federal Public Prosecutor's Office of Belgium, March 9, 2021 - [Contemporaneous reporting on Operation Onymous](https://takedownindex.org/sources/major-independent-news-organizations-contemporaneous-reporting-on-operation-onym), Major independent news organizations, November 7, 2014 - [NCA statement on Operation Tovar](https://takedownindex.org/sources/national-crime-agency-nca-statement-on-operation-tovar), National Crime Agency, June 2, 2014 - [NCA statement on the Webstresser takedown](https://takedownindex.org/sources/national-crime-agency-nca-statement-on-the-webstresser-takedown), National Crime Agency, April 25, 2018 - [NCA statement on the Welcome to Video investigation](https://takedownindex.org/sources/national-crime-agency-nca-statement-on-the-welcome-to-video-investigation), National Crime Agency, October 16, 2019 - [Secureworks analysis of the Gameover Zeus peer-to-peer network and its disruption](https://takedownindex.org/sources/secureworks-secureworks-analysis-of-the-gameover-zeus-peer-to-peer-network-and-i), Secureworks, July 1, 2014
