Altenen Data Breach

What happened

In June 2022, the malicious "carding" (referring to credit card fraud) website Altenen suffered a data breach that was later redistributed as part of a larger corpus of data. The data included 1.3M unique email addresses, usernames, bcrypt password hashes and cryptocurrency wallet addresses.

Exposed data

Recommended actions

• Change your Altenen password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Altenen — attackers weaponise breach data quickly.
• Check whether your email address appears in this breach on haveibeenpwned.com.
