At Sendio, email security is our number one priority. On May 3, 2017, at approximately 18:30 UTC, we became aware of a massive phishing campaign that is being distributed by a fake invitation to a Google document. If your company has been hit with an unexpected email with the subject line “<Person> has shared a document on Google Docs with you”, do not click the link in the email — even if the email appears to be from someone you know.
While this is not a Sendio issue, these attacks are precisely what our suite of products protect against. If you’re organization has been affected by this phishing attack, contact our team to start protecting your enterprise email system right away.
