In case you have a Lenovo computer-don’t forget to carefully read further. Your ThinkPad, ThinkCentre, ThinkStation as well as all V-E-B-K series of computers have been found to have critical security flaws by researchers at IOActive. These flaws were notified to Lenovo-who immediately released an update patch in April 1’.
In case your system has not been updated, please check with your local dealer for more details as they would be automatically updated in system updates. Earlier, Lenovo systems were found to be pre-loaded with an adware program called Superfish-which was then removed by them. These three flaws were related to easily predictable security tokens, validation errors as well as a race condition giving hackers easy high level access permissions for your system.
