text: Lenovo Customer Feedback program At a third time in 2015, criticism arose that Lenovo might have installed software that looked suspicious on their commercial Think-PC lines. This was discovered by Computerworld writer Michael Horowitz, who had purchased several Think systems with the Customer Feedback program installed, which seemed to log usage data and metrics. Further analysis by Horowitz revealed however that this was mostly harmless, as it was only logging the usage of some pre-installed Lenovo programs, and not the usage in general, and only if the user allowed the data to be collected. Horowitz also criticized other media for quoting his original article and saying that Lenovo preinstalled spyware, as he himself never used that term in this case and he also said that he does not consider the software he found to be spyware.
  Lenovo Accelerator
  As of June 2016, a Duo Labs report stated that Lenovo was still installing bloatware, some of which leads to security vulnerabilities as soon as the user turns on their new PC. Lenovo advised users to remove the offending app, "Lenovo Accelerator". According to Lenovo, the app, designed to "speed up the loading" of Lenovo applications, created a man-in-the-middle security vulnerability.
  U.S. Marine network security breach
  In February 2021, Bloomberg Businessweek reported that U.S. investigators found in 2008 that military units in Iraq were using Lenovo laptops in which the hardware had been altered. According to a testimony from the case in 2010, "A large amount of Lenovo laptops were sold to the U.S. military that had a chip encrypted on the motherboard that would record all the data that was being inputted into that laptop and send it back to China". Lenovo was unaware of the testimony and the U.S. military did not inform the company of any security concerns. A Lenovo spokesperson stated that "we have no way to assess the allegations you cite or whether security concerns may have been triggered by third-party interference."
