CCC Censored

The Chaos Computer Club recently announced that their website was being blocked by Vodefone as part of their participation in the “Great Firewall of Britain”. This is somewhat concerning as they don’t seem to match any of the criteria for blocking that have been announced. This also blocks access to information and tickets for their upcoming conference. Many people predicted (me, EFF, and many others)  that this censorship system would inevitable overreach when it was first announced. (more…)

Security researcher Emil Kvarnhammar of TrueSec announced the discovery of a new vulnerability in Mac OS X from 10.8.5 though the current 10.10.

The attack is against a unix utility called “sudo” which allows commands to run as the “root” user (which has absolute power on the system). Normally a user with admin privileges needs to type in their password and approve the running of these tasks, but this attack bypasses the user authentication step.

They have not released details on the vulnerability to give Apple time to issue a fix. In the mean time, it looks like you can protect yourself by making your your normal account is not an admin account. (more…)
