There is a fake ‘shared google docs’ email landing in inboxes everywhere. It will NOT share a document with you, but instead grants a hacker access to your gmail contacts list. DO NOT CLICK IT.
If you carefully mouse-over the link, you will see the code that shows it will share contacts with the hacker(s).
We are certain that Google will be working to close this loophole, but in the meanwhile, many thousands, if not millions of people are falling for this, and handing over their Gmail contacts to the hackers/scammers.
We also expect anti-malware providers to be updating the email protection modules with a definition to detect this type of scam.
