**Google has confirmed to BBC News that it’s e-mail system - Gmail - has been targeted as part of an “industry-wide phishing scheme”.**The search giant said that it had taken immediate action to safeguard the affected accounts.
Phishing involves using fake websites to lure people into revealing data such as bank account details or login names.
BBC News has seen two lists that detail more than 30,000 names and passwords that have been posted online.
“We recently became aware of an industry-wide phishing scheme through which hackers gained user credentials for web-based mail accounts including Gmail accounts,” said a Google spokesperson.
“As soon as we learned of the attack, we forced password resets on the affected accounts. We will continue to force password resets on additional accounts when we become aware of them.”
The firm stressed that the scam was “not a breach of Gmail security” but rather “a scam to get users to give away their personal information to hackers”.
‘Industry problem’
The phishing scam was originally thought to just target Hotmail users.
It was brought to light when 10,000 Hotmail addresses were posted online at Pastebin, a website commonly used by developers to share code.
“I’d…recommend that people change the password on any other site where they use it”

Phishing attack targets Hotmail
The list was reported by technology blog Neowin.
However, a second list has since emerged containing e-mail addresses and passwords from Hotmail, Yahoo, AOL, Gmail and other service providers.
Some of the accounts appear to be old, unused or fake. However, BBC News confirmed that many - including Gmail and Hotmail addresses - were genuine.
Other addresses include Comcast and Earthlink accounts.
It is not clear whether the new list was part of the same phishing attack that collected the Hotmail addresses or a separate scam.
A spokesperson for Microsoft said phishing was an “industry-wide problem”.
“Our guidance to customers is to exercise extreme caution when opening unsolicited attachments and links from both known and unknown sources, and that they install and regularly update their anti-virus software.”
Both lists have since been removed.
However, security expert Graham Cluley of Sophos advised users to change their passwords as soon as possible.
“I’d also recommend that people change the password on any other site where they use it,” he said.
About 40% of people use the same password for every website they use, he added.
