Academics Devise New Way to Steal Data from Air-Gapped Computers
Stealing data from air-gapped computers is one of the great exercises in computer security: advanced attackers covet what’s stored on these isolated machines, while researchers try to figure out the novel ways adversaries could jump those gaps. The latest effort doesn’t involve USBs, heat,...
broken AMD FPU FIP/FDP/FOP leak workaround
ISSUE DESCRIPTION There is a workaround in Xen to deal with the fact that AMD CPUs don't load the x86 registers FIP and possibly FCS, FDP and possibly FDS, and FOP from memory via XRSTOR or FXRSTOR when there is no pending unmasked exception. See XSA-52. However, this workaround does not cover al...
Using Heat to Jump Air-Gapped Computers
When heat from one computer is emitted and detected by an adjacent computer, a channel can be opened that researchers are claiming can facilitate the spread of keys, passwords and even malware. According to researchers from the Cyber Security Research Center at Ben Gurion University in Israel, th...

Researchers Propose New Steganography System for Hiding Data
A group of researchers has developed a new application that can hide sensitive data on a hard drive without encrypting it or leaving any obvious signs that the data is present. The new steganography system relies on the old principle of hiding valuables in plain sight. Developed by a group of...
CVE-2008-3875: Undefined Security Weakness
The kernel in Sun Solaris 8 through 10 and OpenSolaris before snv90 allows local users to bypass chroot, zones, and the Solaris Trusted Extensions multi-level security policy, and establish a covert communication channel, via unspecified vectors involving system calls...
