Researchers from Tel Aviv University have used "Acoustic Cryptanalysis" to acquire the encryption key to a 4096-bit RSA encrypted laptop. The method of attack involves recording the sounds generated by a system while it is accessing the sensitive information, the reason that this is possible is that the system generates unique low-frequency sounds during the decryption process. Originally when the researchers presented their findings in 2004, they had only noted that the systems generated this noise but it wasn't until now that they were able to prove that the encryption keys could be extracted in under an hour.
Lenovo has added two new Haswell-based ThinkPad laptops to their TopSeller line-up just in time for the holidays.
Our service techs have noticed a rash of system infections with a new threat. This new infection is not being caught by any antivirus software to date; it is a breed of computer virus known as "Ransomware". This type of virus will often encrypt vital system files and user data, rendering their computer unusable unless the user pays a ransom for the decryption key.
Unlike previous iterations of this type of virus this one is capable of affecting data on a network. If anyone even suspects a machine has been infected they need to disconnect that machine from the network ASAP and not put it back on until it has been certified as clean.
Contact your IT service provider immediately if a machine is infected.
As with other computer virus threats vigilance is key - be very careful when opening any links or attachments in email.
Yesterday Microsoft finally released the first "Service Pack" for their much maligned Windows 8 Operating system. The free upgrade for current Windows 8 users is available for download through the Windows Store application, as opposed to a downloadable installer or Windows Update that were the norm with previous major OS updates.
