YubiKey NEO is a dongle that supports both contact (USB) and contactless (NFC, MIFARE) communications to secure your Windows, Mac OS or Linux computers and/or Android/iOS smartphones using two factor authentication. It supports one-time password (OTP), smart card functionality (OpenGPG, PIV…), as well as FIDO Alliance’s Universal 2nd Factor (U2F) protocol. The key can be used in a variety of applications, such as logging into your computer, accessing gmail, github, dropbox, and other accounts, and disk encryption. It also works with password manager such as Lastpass or Dashlane. You’ll need to both enter your password, and connect the Yubikey to your computer to be able to login, and for NFC enabled smartphones, you’d need to tap the key on the device. In case you lose your key, online services usually have recovery mechanism in places, and some support registration of up multiple YubiKeys. The latter can probably be used for […]
Allwinner News – Root Exploit in Linux and Fake Pine A64 Boards
There’s been a lot of buzz about a root exploit in Linux 3.4 kernel for Allwinner H3/H83T SoCs found by linux-sunxi & armbian developers in the last few days. Since the kernel for H3 / H83T is stuck to 3.4, and not always updated on the vast majority of hardware platforms, it’s quite likely there are many ways to breach into such systems, and even the majority of Android devices are not secure, not only the ones powered by Allwinner. So I did not really pay attention at first, but it went viral with stories reporting a hidden backdoor, and hitting to ill-intent. But is that really the case? That’s the code from github, now removed from the master branch, but still in A83T branch. It’s now super easy to gain root access by simply running one command which works for any users:
1 |
echo "rootmydevice" > /proc/sunxi_debug/sunxi_debug |
That’s obviously pretty bad, but is […]
Mini Review of NextDrive Plug for Private Cloud Storage and Home Security
NextDrive Plug is an ARM based plug computer that’s used to store your photos or music, and/or as a security system using a webcam combined with Pixi motion sensor. They had a successful crowdfunding campaign, and now that they’ve sent rewards to backers, I’ve also received NextDrive Plug and Pixi for evaluation. The courier was not particularly gentle with the packages, but the devices themselves were not damaged. NextDrive Plus package included the box, a US plug, and a user’s manual in English. Pixi comes with two 3M stickers, and a user’s manual. There’s also a plastic film to avoid depleting the battery, that you’ll need to remove before using the sensor. The interfaces on the plug are minimal with a USB port for a USB mass storage device (HDD, flash drive…) and/or a UVC webcam, and the socket for the power plug adapter on the back.You can then plug […]

Embedded Systems Conference 2016 Schedule – April 13-14
The Embedded Systems Conference 2016 will take place in Boston on April 13-14, and the organizers have now released the schedule, minus some keynotes, which features four main tracks: Embedded Hardware, Embedded Software, Connected Devices and the Internet of Things (IoT), and the ESC Engineering Theatre. As usual, I’ve gone through the list of talks and composed my own little virtual schedule which ended up with sessions focusing on power management, IoT, and security, as well some optimization and drivers development talks among others, such as patents, and the origin of Gerber files. Wednesday 13 8:00 – 9:00 – Power Management in Embedded Systems by Colin Walls, Embedded Software Technologist, Mentor Graphics The importance of power management in today’s embedded designs has been steadily growing as an increasing number of battery powered devices are developed. In this session, we will discuss design considerations that should be made when starting a […]
