Altenen Data Breach

Reported fields are cryptocurrency wallet addresses, emails, bcrypt password hashes, and usernames. This is not a breach of an exchange or wallet provider.

The local record measure is 1,273,854, which is 6,153 above the external unique-email measure. Neither figure means unique people, active forum members, wallet owners, or rows containing every field together. A wallet address may be public on a blockchain, but its linkage to a particular email or username is sensitive.

A row establishes only actual fields in the dataset. It does not establish identity, an Altenen account or participation in unlawful activity, wallet ownership, balance, or transactions, a private key, payment card, username or password ownership, field co-occurrence, account takeover, or misuse.

Forum, wallet, email, username, and credential associations require the strictest private handling. A bcrypt hash is not plaintext; if the password is authenticated and was reused elsewhere, it should be replaced. If actual harassment or threats occur, evidence should be preserved and trusted support appropriate to the circumstances should be used.
