We received an email to our admin email: "taniwallach@gmail.com invited you to join the WW-security-announce group." The link appears to resolve to the URL groups.google.com/d/forum/ww-security-announce.
Is this a real thing? I've received too many "invitations" to Google groups that are anything but legit, to accept this one at face value. I'd appreciate if someone could let us know. If that needs to be by email, rather than this forum, please post an email address we should contact.
Thanks!
