A 'phishing' email is currently being sent to many people in the Collaboration.
The message pretends to be from firstname.lastname@example.org, with the subject" Confidential Document". The email invites you to click a "Google Docs" link. DO NOT FOLLOW THE LINK IN THE EMAIL.
Simply receiving the email will not have put you at risk. We are investigating exactly how we were targteed for this, eg if a Cochrane contributor's email was hacked. We do not have any indication that central data (eg Archie) has been accessed.
