    noway reacted to c.frio for an article, Apple issues a fix for ethernet disabled by a recent OS X update   
    Ethernet. Don’t be embarrassed if you have no idea what it is; after all, Apple doesn’t even include an ethernet port on its laptops anymore. For the uninitiated, it’s a network connection type that involves using an actual cable.
    On the desktop, though, Apple still includes an ethernet port. Recently, Apple issued a minor kernel extension update for OS X, but the update had a bug that disabled ethernet. Apple fixed the offending update, but if you installed the update and still see problems, Apple has a support article for troubleshooting and fixing your disabled ethernet.
    If you have an ethernet and Wi-Fi working at the same time, you may not have noticed your ethernet connection not working. So it’s worth a few minutes of your time to check your connection.
    See if the bad update was installed
    Follow these steps to see if the update was installed on your Mac.
    Launch the System Information app (Applications > Utilities or hold down the Option key and select Apple menu > System Information. In the left column, look for the Software header and expand it if needed. Select Installations. In the list in the top section of the main window, click the Software Nameheader to alphabetize the list. Scroll though the list and look for “Incompatible Kernel Extension Configuration Data” in the Software Name column. Then look at the version number. If the version is 3.28.1, you have the bad update and will need to get the latest version.
    Install the new update via Wi-Fi
    Wi-Fi still works, and you’ll use it to get the update. Get connected over Wi-Fi and follow these steps.
    Launch Terminal (Applications > Utilities). Enter the following:
    sudo softwareupdate —background This will update Incompatible Kernel Extension Configuration Data to version 3.28.2, which will correct the problem.
    How to fix without an Internet connection
    If you can’t use Wi-Fi, the fix is more complicated. It involves booting into Recovery Mode, using Disk Utility to mount your Mac’s internal drive, running Terminal, entering a command to fix ethernet, restarting, and then using an ethernet connection to get the fixed update. Apple has the complete instructions.

    noway got a reaction from Rene for an article, The Pita Bread Atack   
    The authors demonstrate the extraction of secret decryption keys from laptop computers, by nonintrusively measuring electromagnetic emanations for a few seconds from a distance of 50 cm. The attack can be executed using cheap and readily-available equipment: a consumer-grade radio receiver or a Software Defined Radio USB dongle. The setup is compact and can operate untethered; it can be easily concealed, e.g., inside pita bread. Common laptops, and popular implementations of RSA and ElGamal encryptions, are vulnerable to this attack, including those that implement the decryption using modern exponentiation algorithms such as sliding-window, or even its side-channel resistant variant, fixed-window (m-ary) exponentiation.

    Malware Persistence on OS X Yosemite.

    Patrick Wardle showed that Yosemite can be compromised with malware rather easily.
    Neither OSX?s built in features, nor the known antivirus apps are a cure seemingly.

    noway got a reaction from noname for an article, Lighteater   
    Because almost no one applies BIOS patches, almost every BIOS in the wild is affected by at least one vulnerability, and can be infected.
    The high amount of code reuse across UEFI BIOSes means that BIOS infection is automatable and reliable.
    Lighteater may infect almost any new or old hardware and hides in flash until it notices "promising" data to collect and send outbound.
    Wiping HDD/SSD aint no cure, only a flashing a trustworthy untouched UEFI may help - until next time.

    If you own one of these:

    Better replace it, as well as similar devices based on nRF24L01+ chipsets.
    The chipset is discussed here: http://travisgoodspeed.blogspot.co.uk/2011/02/promiscuity-is-nrf24l01s-duty.html
