TLS Certificate Updates
The current TLS certificates for www.cobaltstrike.com and verify.cobaltstrike.com both expire on November 16th 2026. The certificates will be updated on or before November 13th 2026. After the certificates are updated, you will need to download the latest Cobalt Strike updater if you want to update Cobalt Strike to the latest version. If you are already using Cobalt Strike 4.13 then you do not need to take any action.
The update program pins the TLS certificates for both www.cobaltstrike.com and verify.cobaltstrike.com and checks them during the update process. If the certificates do not match the ones that the update application is expecting, then you will see a warning message about the server being untrusted.
The latest version of the update application (20261109) is available now. Simply download and extract the distribution package for your platform to get the latest version.
