Evening, Forwarding this to this list as I am aware thinkpad is popular. Looks though like Lenovo is shipping a really dirty adware How can they have fallen for this?

While preloaded adware is bad enough, Superfish does something even worse: to allow itself to MITM SSL-/TLS-protected web traffic, it installs a CA into the Windows trusted root certificate store. This CA is apparently pre-generated and its corresponding private key comes with every installation of Superfish. Furthermore, uninstalling Superfish does not remove this CA, so all users running Lenovo's tainted Windows installation are affected, even if they took the time to uninstall Superfish. A user on Twitter has apparently forged a certificate for Bank of America's online banking system [4] and I expect that we will see more of these shenanigans to come to light over the next few days. According to a thread on Lenovo's customer support forum [1], they are no longer pushing this adware on customers and are asking the authoring company to push a fix for this ASAP. Mozilla also has an issue on their tracker to mark the offending cert as "untrusted" in NSS. [5] Thoughts? [1] https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Lenovo-Pre-instaling-ad...
