Executive Summary
In 2020, a corpus of nearly a quarter-billion records spanning over 400 fields was circulated within the hacking community and misattributed to Acxiom. It contained about 51.7 million unique email addresses along with names, phone numbers, physical addresses, and IP addresses. Acxiom stated the data does not originate from it and is not an Acxiom breach; HIBP lists the data as unverified.
ObscureIQ assessment: Because the data is aggregated marketing information of uncertain origin, presence does not indicate any specific company was breached; the exposure is of contact/identity attributes rather than credentials.
Breach Impact
The marketing-style identity and contact data supports spam, phishing, and profiling, but it should not be associated with Acxiom; the true source is unestablished.
About Not Acxiom
This record is a large marketing-style dataset that was falsely attributed to the database-marketing company Acxiom; it does not originate from Acxiom.
Why They Hold Your Data
Misattributed dataset involving marketing or consumer profile records that were circulated under an inaccurate association with Acxiom. The object of concern is the exposed data corpus rather than a reliably documented breach of the named entity.
Recent Developments
Acxiom reviewed the claims and concluded the data does not come from Acxiom and is not the result of any Acxiom breach.
