Google Docs Phishing campaign – May 3, 2017

Update May 4, 2017: We  would like to clarify that Zscaler customer data, logs, policy data as well as cloud infrastructure were not impacted by this phishing campaign and do not utilized any Google services or applications.

An aggressive phishing campaign went viral earlier today, which impacted multiple Google users including enterprise Google deployments. A few Zscaler employees also received these phishing e-mails. The campaign involved an unsuspecting user receiving an email with a Google Doc link from one of their known contacts. If the user clicks on the link and further grants access, their contacts would be leveraged to send the same phishing e-mail with a link from the impacted user account.

The attack involved squatted domains that were recently registered and hosting the malicious web app. Zscaler implemented blocks for multiple domains tied to this campaign cloud wide within minutes of initial reports. Google was quick to resolve this issue and has posted official response here.
