Major email marketing organization accidentally exposes over billion people's data

Synopsis

Described at the time it was disclosed (March 2017) as the largest single data breach in history, with 1.34 billion individual records compromised. The records largely consisted of email addresses, but some of the entries had additional details like IP addresses, names and physical addresses.

This data breach was discovered by the efforts of a security researcher and it was claimed was due to an error setting up a backup.

The company filed a lawsuit against the researcher in May 2017 alleging that the researcher "perpetrated a coordinated, months-long cyberattack against River City and its principals."
