Starting in late May, we observed a marked increase in volume and sophistication of spam submissions to public Smartsheet Forms \(forms available to the general public and not requiring a Smartsheet login\), even with the Captcha setting enabled. This resulted in some customers experiencing an increase in unwanted spam content, frequently containing cryptocurrency or phishing links, delivered into their sheets. The activity was generated by automated bots operating through anonymized networks and proxy services. This primarily impacted but was not limited to the US region. Once the abuse was identified, we evaluated, deployed, tested, and tuned a series of protective measures over the following weeks. Because automated abuse of this kind adapts over time, addressing it requires an iterative approach: we layered multiple protections in both forms, captcha service, and the underlying infrastructure, evaluated their effectiveness against live traffic, and refined them as we learned more,
This is now resolved. We are still actively monitoring spam levels as an ongoing and evolving strategy. We encourage all customers to submit support tickets for any residual spam coming through so we can continue to fine tune our solutions.
We have implemented measures to address the increased spam activity with Smartsheet public forms. We will continue monitoring and make further adjustments as needed. If you are continuing to see a high rate of spam submissions, please contact our support team so that we can investigate further.
We are aware that some customers are receiving an increased volume of unwanted spam submissions through public Smartsheet forms, even with reCAPTCHA enabled. Our teams have been actively investigating and deploying additional protections. We are observing a decrease in spam activity as we continue applying and evaluating further mitigations. Who is affected: Customers who use public forms that do not require login.
