Since April, a hacker with a history of selling stolen data has claimed a data breach of billions of records — impacting at least 300 million people — from a U.S. data broker, which would make it one of the largest alleged data breaches of the year.
The data, seen by TechCrunch, on its own appears partly legitimate — if imperfect. The stolen data, which was advertised on a known cybercrime forum, allegedly dates back years and includes U.S. citizens’ full names, their home address history and Social Security numbers — data that is widely available for sale by data brokers.
