Abstract

Security firm finds millions of stolen credentials and email addresses on the black market.

360 million stolen credentials and 1.25 billion email addresses were found on the black market last month by security firm Hold Security.

The firm believes that the 360 million credentials come from multiple breaches that have not yet been publicly disclosed (and may not even be known about by the victims) – with a single breach accounting for 105 million of the stolen credentials. Many of the passwords paired with usernames were in plaintext.

The stolen email addresses are from all the popular email providers such as AOL, Gmail, Microsoft and Yahoo!, but also include addresses from a large number of the Fortune 500 companies and several nonprofit organizations.
