What happened

In August 2018, the adult furry interactive game creator HTH Studios suffered a data breach impacting multiple repositories of customer data. Several months later, the data surfaced on a popular hacking forum and included 411k unique email addresses along with physical and IP addresses, names, orders, salted SHA-1 and salted MD5 hashes. HTH Studios is aware of the incident.

What to do if you had an account

  1. 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.
  2. 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.
  3. Watch for scam calls and SIM swaps. Be suspicious of calls and texts that claim to be from your bank or a courier. Ask your mobile operator for a port-out or SIM-change PIN if it offers one.
  4. Guard against identity fraud. Identity documents and dates of birth cannot be changed like a password. Consider a credit freeze or fraud alert where your country offers one, and be wary of anyone who 'verifies' you using those details.
