USPS employee data has been found in a database recently leaked online, according to a report from ZDNet:
NEW YORK — Millions of records from a commercial corporate database have been leaked.
The database, about 52GB in size, contains just under 33.7 million unique email addresses and other contact information from employees of thousands of companies, representing a large portion of the US corporate population.
Dun & Bradstreet, a business services giant, confirmed that it owns the database, which it acquired as part of a 2015 deal to buy NetProspex for $125 million.
Troy Hunt, who runs breach notification site Have I Been Pwned, obtained the database and analyzed the records.
In a blog post Tuesday, Hunt said the breakdown was entirely US-focused. California was the most represented demographic, with over four million records, followed by New York with 2.7 million records and Texas with 2.6 million records.
Hunt’s analysis of the records showed that the leading organization by records is the Department of Defense, with 101,013 employee records, followed closely by the US Postal Service with 88,153 employee records.
