Not Acxiom data breach
51,730,831 accounts · breached June 21, 2020
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 2020, a corpus of data containing almost a quarter of a billion records spanning over 400 different fields was misattributed to database marketing company Acxiom and subsequently circulated within the hacking community. On review, Acxiom concluded that "the claims are indeed false and that the data, which has been readily available across multiple environments, does not come from Acxiom and is in no way the subject of an Acxiom breach". The data contained almost 52M unique email addresses.
What data leaked
- Email addresses
- IP addresses
- Names
- Phone numbers
- Physical addresses
What to do if you had an account
- 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.
- 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.
