I fail to see the security issue here, the Equifax certificate in question (thumbprint: d23209ad23d314232174e40d7f9d62139786633a) has been revoked (on Windows 10 at least) - it is in the system store to protect users by being marked as revoked and thereby marking all child certificates and signatures as invalid. I strongly suspect all the other listed certificates are also marked as revoked but I couldn't be bothered wasting my time checking.
