This is a significant wake up call for all organizations that rely on RSA's SecurID for strong authentication. RSA was hit by APT (Advanced Persistant Threats), meaning it is no coincedent that RSA was hacked - they were targeted with a specific intention behind the attack.
All SecurID users should seriously consider alternatives immediately.
