KomikoAI 2026 Data Breach

The external breach record supplies February 25, 2026, a measure of 1,060,191 unique emails, and four data classes. The entry was published March 2, and a public announcement that day states only that a breach occurred. The initial access method, the time the data was obtained, the company's discovery date, and its security response have not been publicly disclosed.

The current komiko.app site confirms that the service is an AI anime, character, and comic-generation platform; it does not publish an incident notice. The site is therefore used to establish company identity, not as first-party evidence for technical breach details.

The structured classes are email addresses, names, forum posts, and user-submitted prompts. The external record explicitly says individual AI prompts could be mapped to specific email addresses. It does not follow that every email occurred with a name and post, or that every prompt contained private or sensitive subject matter.

Passwords, session tokens, API keys, payment cards, subscription records, physical addresses, and phone numbers are not verified classes in the record. Broader field claims that lack a public first-party notice or an independent dataset analysis were not added to this entry.

The live catalogue has no KomikoAI import job, and the email, username, password, sensitive-data, and general breach-data collections contain zero local associations for this identity. The 1,060,191 figure is only the external unique-email measure and is not presented as locally searchable records. No second record matching the same company and event date was found.

Linkage between an email and a prompt can make contextual phishing or impersonation more convincing. A match alone does not prove who controlled the account, that all posts came from one person, or that a prompt concerned a private topic. People who know they used the service should verify unexpected login or password-reset messages by opening komiko.app directly and should not trust links or one-time-code requests delivered by email.
