What happened
In January 2017, the free hidden service host Freedom Hosting II suffered a data breach. The attack allegedly took down 20% of dark web sites running behind Tor hidden services with the attacker claiming that of the 10,613 impacted sites, more than 50% of the content was child pornography. The hack led to the exposure of MySQL databases for the sites which included a vast amount of information on the hidden services Freedom Hosting II was managing. The impacted data classes far exceeds those listed for the breach and differ between the thousands of impacted sites.
What data leaked
- Email addresses
- Passwords
- Usernames
What to do if you had an account
- 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.
- 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.
- 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.
