You don't need to do anything. There is no evidence that JetBrains products were affected.
Does this affect your IDEs and other tools?
Our IDEs are standalone tools and bear no relation to TeamCity, other
than the fact that we use our own installation of TeamCity to build
them. We have no evidence that indicates that any of our servers or
our standalone tools have been tampered with, and much like is the
case with TeamCity, we run regular security audits on our tools and
systems.
Am I safe in using JetBrains tools?
None of the articles published so
far, including those referencing investigations by the FBI, as well as
quotes from SolarWinds themselves, show any evidence that TeamCity has
any vulnerability or backdoor that would have allowed unauthorized
access to the build process.
As such we have no knowledge or evidence to believe that any of our
tools may have been compromised, and consequently do not believe that
you are at any risk in continuing to use our tools.
We hope that the investigation with SolarWinds is finalised as soon as
possible and clears up any misrepresentation of our tools and our
company. We’d also like to reiterate that we offer our full
cooperation with any governmental agencies and security researchers.
For over 20 years, one of our pillars has been to be transparent,
honest, and truthful with our customers, and nothing hurts us more
than seeing unfounded allegations that damage our reputation and
instil doubt on our customers.
We highly appreciate your support and will keep you updated on any
progress.
