Using Computer Clock Skew to Crack Anonymity Networks

At the recent Chaos Communications Congress, Steven J. Murdoch, a researcher in the security group at the University of Cambridge, discussed how clock skew can be used to facilitate a digital attack against anonymity networks. Clock skew, the tendency for a computer’s clock to become less precise when heated, can reduce the efficacy of anonymizers, such as the Electronic Frontier Foundation’s Tor network.

The Internet Freeway May Become A Toll Road

There are no traffic cops on the internet. Until now, that is. If U.S. telecommunication companies have their way, we may have internet traffic cops, patrol cars, and a full police union. The traffic cops will direct the traffic, giving preferential treatment to a select few that are able to pay for the unimpeded toll lane. Those who are able to pay the toll will get faster service.

Reset Your Digital Watch, Saturday Night

The International Earth Rotation and Reference Systems Service
(IERRSS) will move time backward one second on December 31, 2005. An
extra second will be added at the end of the year to to account for
the slowing of the Earth’s rotation. The IERRSS recognizes that our
planet’s pace of rotation is unpredictable, and will institute the
first leap second in seven years. Normally the leap second is a
nearly annual event.

Cellphone Users Beware: We Know Where You Are

Do you carry a cellphone? Do you know that your cellular service provider knows where your phone is? By extension, if you carry your phone with you, your cellular service provider knows where you are. Cellular phones can be located, accurate to within about 300 yards, whenever they are turned on. Since most cellular phone users keep their phones on and with them most of the time, it is quite probable that their ongoing whereabouts are being automatically tracked.

Sony CD Security Fix Leaves Users Unsecured

Sony BMG Music Entertainment attempted to protect some of its music CDs from digital piracy by automatically installing copy protection software on the computers of users who attempted to play the music CDs on their computers.
