Security Update for Keeper Browser Extension

Security Update for Keeper Browser Extension

by Craig Lurey, CTO at Keeper Security, Inc. – August 26, 2016

Keeper holds the security of our customers and their data as our highest priority. To mitigate the possibility of an online clickjacking attack during a browser session, we have updated our Keeper Browser extension. We have made two security enhancements based on the analysis provided by Tavis Ormandy, a highly-respected security analyst at Google.

Yesterday, we received a report regarding this potential security risk. It related to a security threat that could potentially be exploited by a clickjacking attack using an on-page feature of the browser extension. In this scenario, a malicious website with intent to attack the extension could entice a user to click on the Keeper lock icon and take advantage of our “Search” feature with the goal of attempting to extract a credential from the vault.

We immediately addressed and resolved this potential vulnerability by removing the “Search” and “Add to Existing Record” features from the on-page browser extension user interface as seen below:
