Exploit.In data breach
593,427,119 accounts · breached October 13, 2016
Have I Been Pwned marks this breach as unverified: the data could not be confirmed as coming from the named service, although it contains real email addresses.
What happened
In late 2016, a huge list of email address and password pairs appeared in a "combo list" referred to as "Exploit.In". The list contained 593 million unique email addresses, many with multiple different passwords hacked from various online systems. The list was broadly circulated and used for "credential stuffing", that is attackers employ it in an attempt to identify other online systems where the account owner had reused their password. For detailed background on this incident, read Password reuse, credential stuffing and another billion records in Have I Been Pwned.
What data leaked
- Email addresses
- Passwords
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.
