Facebook Marketplace data breach

What happened

In February 2024, 200k Facebook Marketplace records allegedly obtained from a Meta contractor in October 2023 were posted to a popular hacking forum. The data contained 77k unique email addresses alongside names, phone numbers, Facebook profile IDs and geographic locations. The data also contained bcrypt password hashes, although there is no indication these belong to the corresponding Facebook accounts.

What data leaked

• Email addresses
• Geographic locations
• Names
• Passwords
• Phone numbers
• Social media profiles

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.
4. 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.
