Security experts are warning that millions of Verizon customer accounts could still be at risk after a data exposure by an Israeli company working for the phone giant.

Chris Vickery, director of cyber risk research at security firm UpGuard, found as many as 14 million customer records for the past six months on an exposed and unprotected Amazon S3 cloud server in late June.

This sensitive data includes millions of individual customer names, phone numbers, and their account PIN, which we confirmed is all that can be needed by an attacker to access a person's account. That can lead to phone number hijacking and account takeovers, which could allow hackers to break into a person's email and social media accounts protected even by two-factor authentication, according to security experts briefed on the exposure prior to publication.

Verizon said that an investigation determined that "no other external party accessed the data," but did not say how it came to that conclusion. The logic goes that if a security researcher found the data, there's no telling who else might have done.
