How is Nest addressing the OpenSSL Heartbleed security issue?

Nest used a version of the OpenSSL library with the Heartbleed bug, which may have affected the Nest Thermostat and the Nest app. Nest Protect was not affected by the Heartbleed bug. We’ve already deployed a software update to fix the issue for the Nest Thermostat and apps. We also recommend that you change your Nest Account password.

We’re committed to protecting your security, and we believe that your personal information and data have not been compromised through the recent OpenSSL flaw.

The Heartbleed bug, a serious vulnerability in OpenSSL, was discovered on April 7, 2014. OpenSSL is a common security protocol that is used to keep your internet communications private. We want to update you about how this affects Nest, what we’re doing about it, and what you should do about it.

How has the Heartbleed bug affected Nest? Is there a fix in place?

While the Nest Learning Thermostat used a version of the OpenSSL library with the Heartbleed Bug, after careful review we do not believe that the vulnerability has affected Nest products. The Heartbleed patch has already been deployed for the Nest app and website.
