The scale of a phishing attack originally thought to be directed at Hotmail may be larger than previously thought.
BBC News has seen a list of more than 20,000 more names and passwords that have been posted online.
The list contains e-mail addresses and passwords from Hotmail, Yahoo, AOL, Gmail and others service providers.
The list was published on the same website as the original list of 10,000 Hotmail login details.
Some of the accounts appear to be old, unused or fake. However, BBC News has confirmed that many - including Gmail and Hotmail addresses - are genuine.
