Lenovo installed a piece of software that could arguably be called malware or spyware. Superfish, as this article indicates, installs a self-signed root certificate that is authoritative for everything. I wanted to be sure that this issue wasn’t present on any of our Lenovo systems, so I turned to PowerShell to help.
I found a copy of the certificate on Robert David Graham’s github here. I pulled the thumbprint from the cert which appears to be: c864484869d41d2b0d32319c5a62f9315aaf2cbd
