Due to the 'Heartbleed bug' – a serious vulnerability that affects many different internet services – you will need to change your CERN passwords before 13 May 2014. Failure to change your passwords may mean your accounts could be blocked.
Most CERN computing services were not vulnerable, but CERN takes computer security very seriously. As a preventive measure the computer security team are asking all owners of CERN computing accounts to now change their passwords.
Passwords can be changed on the CERN account management website. You will get a dedicated email message if you have not yet taken any action.
For all computer security matters please refer to cern.ch/security
