The following response was provided by Robert Relyea:

    For most token users, nothing. The researchers have not extracted
    the RSA private key, they extracted a symmetric key that is
    encrypted to the private key on the token. In environments where the
    token does not support decrypt, and operate on FIPS level-3 or
    above, this is big news, but for deployments which use a basic
    "RSA-op" function, not even separate Sign/Decrypt functions, you can
    simply decrypt the blob and get the symmetric key.

    The paper is definitely worthy of attention, but for most
    deployments it will have little or now impact.
