If you are a Verizon customer, you should be getting notification that the company has suffered a leak of personal details of 14 million customers.

The data was stored on an unprotected Amazon S3 cloud server was left open by a third party vendor. Security firm UpGuard discovered the data which included names, phone numbers, and account PINs (personal identification numbers) which could allow a hacker access to the customer’s account.

"The exposure of Verizon account PIN codes used to verify customers, listed alongside their associated phone numbers, is particularly concerning," explained UpGuard's Dan O'Sullivan in a blog post.

Chris Vickery, from UpGuard, has discovered other such lax security. Last month he discovered an unsecure Amazon S3 server owned by data analytics firm Deep Root Analytics (DRA) that had left exposed information of more than 198 million United States citizens.

In March, he discovered a cache of 60,000 documents from a US military project on a Amazon cloud server. The same month he discovered nearly 1.4 Billion user records on an unsecured and publicly exposed server linked to River City Media (RCM).

Worrisome is a discovery in 2015 of more than 191 million US voter records.
