First
of all thanks for attending Google Developer Day yesterday, we hope you
found it useful. Unfortunately, we need to let you know about an
incident which took place during the conference which you may need to
take precautionary action on.
We
identified unauthorised activity on the public wired Ethernet network
which was provided by the convention centre for conference attendees to
access the Internet. This
may have affected a limited number of attendees accessing websites and
online applications through the wired Ethernet connection. We have no
evidence so far to suggest that the wireless network also provided at
the event, and which was used by most attendees, was affected.
Due
to the unauthorised activity, there is a chance that if you used the
wired network, any user name and password entered to access a website
may have been put at risk. When trying to access a
secure website (a website using https), you may have received an alert
indicating that the page had an invalid security certificate. In any
case, we advise users as a precaution
to change the passwords for any websites or services they accessed
through the wired connection during the conference.
We're really sorry that this has happened but we believe that the vast majority of attendees won't have been affected by this incident. In the meantime, we look forward to seeing you at future events very soon.
