Lenovo Does It Again!


Lenovo has a bad track record, as they were found to be selling laptops pre-installed with Superfish malware a few months ago. Not just that, Lenovo got banned from supplying network equipment for defense services in various countries due to hacking and spying concerns.

Rootkit dubbed as "Lenovo Service Engine (LSE)"


According to Lenovo it is a piece of code inbuilt into the firmware on the computer's motherboard. During windows is installation process, the LSE automatically downloads and installs Lenovo's own software during boot time before the Microsoft operating system is launched, which overwrites Windows operating system files. It injects software that updates drivers, firmware, and other pre-installed apps onto Windows machine, even in case of a clean reinstall of OS. This causes the hidden LSE in the firmware will automatically bring them back as soon as the machine powered on or rebooted.

Impact Of The LSE Rootkit


It has varying destructive impacts for Desktops and Laptops. As per the company claims it sends some basic information like the system model, date, region, and system ID etc to a Lenovo server, just for one time, except any personal data. In case of Laptops it's a different story. LSE installs a software program called OneKey Optimizer (OKO), which according to the company enhances the computer performance by updating the firmware drivers,pre-installed apps, removes junk files and find ways to optimize system performance. But in reality the OneKey Optimizer falls under the category of "crapware" and both LSE as well as OKO appears to be insecure. Holy crap! Isn't it?

Who Are Affected?


According to official statements from Lenovo the new systems that were built since June don't have the BIOS firmware that causes the issue and it's no longer installing Lenovo Service Engine on new PCs. Many Flex and Yoga machines running operating systems including Windows 7, Windows 8, and Windows 8.1 are affected by this issue. Full list of affected notebooks and desktops can be seen on Lenovo's website.
