GateHub data breach

What happened

In October 2019, 1.4M accounts from the cryptocurrency wallet service GateHub were posted to a popular hacking forum. GateHub had previously acknowledged a data breach in June, albeit with a smaller number of impacted accounts. Data from the breach included email addresses, mnemonic phrases, encrypted master keys, encrypted recovery keys and passwords stored as bcrypt hashes.

What data leaked

• Email addresses
• Encrypted keys
• Mnemonic phrases
• Passwords

What to do if you had an account

1. Change the password. Change your password on this service. If you used the same password anywhere else, change it there too: attackers try leaked email and password pairs on other sites automatically. A password manager makes one unique password per site practical.
2. Turn on two-step sign-in. Enable two-factor authentication where the service offers it, preferably with an authenticator app or a passkey. A leaked password alone is then not enough to get in.
3. Expect targeted phishing. Leaked contact details are used to write convincing fake messages that mention the breached company or your real name. Do not click links in unexpected emails or texts about this account; go to the site by typing its address.
