first-0xd0-byesAuf dem 31c3 hab es einen interessanten Vortrag über die Sicherheit von UEFI gesehen – Attacks on UEFI security, inspired by Darth Venamis’s misery and Speed Racer, davon lies sich der Autor dieser interessante Dokumentation inspirieren, wie sich RootKits recht gut in UEFI-System einpflanzen lassen.

Cr4sh dokumentiert recht eindrucksvoll und ausführlich einen erfolgreichen Angriff gegen die UEFI-Sicherheitsmaßnahmen seines Intel DQ77KB.
Der Sourcecode für den Exploit findet sich bei GitHub

cachestructOn the European security conference OHM 2013 a security researcher has demonstrated an attack that would allow a hacker to access and modify the Flash Firmware on a hard drive and program it to protect his access.

Firmware is code stored on a special flash-able chip on the drive. The built in code tells the drive how to work, how to read and write data. It is flashable (it can be reprogrammed) so the manufacturer can release updates to the firmware. Most people never re-flash or update their hard drive firmware. Continue reading »

hdmi-loopAdam Laurie verdeutlichte in seinem Artikel HDCP is dead. Long live HDCP. A peek into the curious world of HDMI copy protection… , dass der HDCP-Kopierschutz schon lange gebrochen ist und wie er sich auch weitere Male mit sehr einfacher Hardware, etwas Geschick und ein paar Zeilen Code aushebeln lässt.

An easier way to update the firmware of your Raspberry Pi it to use rpi-update written by Hexxeh.

To install the tool, run the following command:

sudo wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && 
sudo chmod +x /usr/bin/rpi-update

If you get errors relating to certificates, then the problem is likely due to one of two things. Either the time is set incorrectly on your Raspberry Pi, which you can fix by simply setting the time using NTP. The other possible issue is that you might not have the ca-certificates package installed, and so GitHub’s SSL certificate isn’t trusted. If you’re on Debian, you can resolve this by typing:

sudo apt-get install ca-certificates

To then update your firmware, simply run the following command:

sudo rpi-update

To upgrade/downgrade to a specific firmware revision, specify it’s Git hash as follows:

rpi-update <git hash> 

If you’d like to set a different GPU/ARM memory split, then define gpu_mem in /boot/config.txt.
