Anonymous published a cache of data taken from Epik in September 2021, and Epik confirmed an unauthorized intrusion into some of its domain-related systems. California’s breach-notification listing gives September 13, 2021 as the known breach date. The leak drew attention both as a security incident and because journalists and researchers examined the records for information about websites and their operators.

Anonymous said it had obtained and released Epik data. The Washington Post reported that the published cache exceeded 150 gigabytes. That figure describes the material Anonymous released, not an independently measured count of records proven authentic.

What data was reportedly exposed?
The Washington Post reported that the cache included customer identifiers and credentials, years of purchase records, internal company email, and records from Epik’s Anonymize privacy service. It described 843,000 transactions spanning more than 10 years, along with nearly a million invoices.
The Post also reported Epik’s notice that 110,000 people were affected by exposure of financial account and card numbers, passwords, and security codes. This is the affected-person count and data description attributed to the company notice by the newspaper; it is not an independently calculated count.

Why did the leak become a public-interest story?
The Washington Post characterized Epik as an internet-services company whose customers included far-right websites. Its reporting described researchers examining the cache to investigate who operated some extremist websites and how sites might be connected. The records also included ordinary domains, and the cache was large enough to require substantial analysis.
That investigative potential does not make every name or alleged affiliation in leaked records reliable. A record may suggest a lead, but attributing a site or account to a person requires independent verification. The presence of an entry in a data dump is not, by itself, proof of identity, ownership, or political affiliation. Reporting on the cache emphasized the need for extensive analysis and fact-checking.

What is confirmed, and what should be treated cautiously?
- State listing: California records Epik Holdings, Inc. and September 13, 2021 as the known breach date.
- Company notice: Epik confirmed an unauthorized intrusion into some domain-related systems in a notice reproduced on September 19, 2021.
- Press reporting: The Washington Post described the size and kinds of material in the cache and reported the company’s stated count of affected people.
- Claims requiring verification: Anonymous’s assertions and individual identities or affiliations inferred from leaked records should not be treated as established facts without corroboration.
The release of sensitive information does not justify republishing it. Credentials, payment details, private addresses, and unverified personal allegations are not necessary to understand the breach or its public significance.
