  • Hackers Can Now Reverse Engineer Intel Updates Or Write Code

    Researchers have extracted the secret key that encrypts updates to an assortment of Intel CPU's, a feat that could have wide-ranging consequences for the way the chips are used and, possibly, the way they're secured.

    The key makes it possible to decrypt the microcode updates Intel provides to fix security vulnerabilities and other types of bugs.

    Having a decrypted copy of an update may allow hackers to reverse engineer it and learn precisely how to exploit the hole it's patching.

    The key may also allow parties other than Intel - say a malicious hacker or a hobbyist - to update chips with their own microcode, although that customized version wouldn't survive a reboot.
