Side-Channel Attack Steals Crypto Key from Co-Located Virtual Machines

Side-channel attacks against cryptography keys have, until now, been limited to physical machines. Researchers have long made accurate determinations about crypto keys by studying anything from variations in power consumption to measuring how long it takes for a computation to complete.A team of researchers from the University of North Carolina, University of Wisconsin, and RSA Security has ramped up the stakes, having proved in controlled conditions that it’s possible to steal a crypto key from a virtual machine.

More VMware ESX Source Code Posted Online

For the third time this year, VMware ESX source code has been posted online.

Some XBOX Live users have violated the online gaming platform’s code of conduct by using a malicious application that allowed them to permanently kill off the characters of other players in the popular ‘Borderlands 2’ video game.

Although DDoS attacks have been a serious problem for more than a decade now and security staffs have a good handle on how they’re executed and how to handle them, attackers constantly adjust their tactics in order to defeat the best defenses available. One of the more recent tactics adopted by attackers is the use of open DNS resolvers to amplify their attacks, and this technique, while not novel, is beginning to cause serious problems for the organizations that come under these attacks.
