Talk API outage to mitigate spam attack
  • Resolved

    Resolved

    Talk is operating as expected; this incident is now resolved.

  • Monitoring

    Monitoring

    The fix is complete and we've restored Talk to working order. We will monitor Talk and the rest of the platform, but you should expect normal operations from this point forward. Please reach out to contact@zooniverse.org if you encounter any persistent issues.

    Update

    The Zooniverse software development team is completing coding and testing for the fix, and we expect Talk to be back up and running by end of day today (Wed Aug 19). Thank you for your patience!

    Identified

    The spam messages have been confirmed to be a phishing effort targeting Zooniverse volunteers. As stated in our recent email newsletter, this attacker impersonated the Zooniverse team by sending direct messages on Talk from accounts named ZooniverseTeam* with a trailing number (e.g., ZooniverseTeam8659). These messages were not sent by the Zooniverse platform and should be deleted. The Zooniverse platform will never request bank information, and any suspicious requests should be reported to security@zooniverse.org and/or contact@zooniverse.org -- as many of you from the Zooniverse community did!

    There is no indication the attacker had any access to Zooniverse user data, or that there are any ongoing issues or anomalies affecting Zooniverse user accounts (as the phishing message claimed). Please remain vigilant against phishing attempts.

    Our dev team is currently removing the spam messages and notifications and is implementing a fix to ensure this attack cannot be repeated. We expect Talk to remain down for at least 48 hours while these mitigations efforts are completed. We will update this thread again when we have a firm timeline for restoring Talk to working order -- likely late on Tuesday 18 August.

    Investigating

    We’ve become aware that a large number of spam messages have been sent to users of our Talk discussion forums. We have brought down Talk to investigate and determine what can be done to mitigate.
