One of the hacker attacks stole over 105 million records making it the single largest data breach in cybercrime history.
The trove included credentials from more than 360 million accounts and around 1.25 billion email addresses.
The discovery was made by cybersecurity firm Hold Security. “These credentials can be stolen directly from your company but also from services in which you and your employees entrust data.
In October 2013, Hold Security identified the biggest ever public disclosure of 153 million stolen credentials from Adobe Systems. One month later we identified another large breach of 42 million credentials from Cupid Media,” the firm said.
They accumulated the data over the past three weeks. The company first tracked over 300 million abused credentials that were not disclosed publicly (that is over 450 million credentials if one counts the Adobe find).
