The phishing scam claimed to come from Google Docs - a service that allows people to share and edit documents online.Users who clicked a link and followed instructions, risked giving the hackers access to their email accounts.
During the attack, users were sent a deceptive invitation to edit a Google Doc, with a subject line stating a contact "has shared a document on Google Docs with you".Victims of the scam were asked to let a seemingly real service called "Google Docs" access their account data.
Google said it had stopped the attack "within approximately one hour", including through "removing fake pages and applications".
