What is happening? Between September 2014 and February 2015, consumer-grade notebook computers by Lenovo were shipped with a pre-installed third-party piece of software called Superfish. This adware software installs an insecure self-signed root certificate in the local trusted certification authority (CA) store, effectively defeating the security provided by SSL/TLS and leaving the computer and the user vulnerable to Man-in-the-Middle attacks.

How does this impact me? If you own or use a consumer-grade Lenovo computer purchased during the above timeframe, you can visit https://filippo.io/Badfish/ to check whether your computer is affected.

My computer is affected, now what? Contact an IT Service Desk<https://connect.uwaterloo.ca/owa/UrlBlockedError.aspx> or your Faculty Service Desk<https://uwaterloo.ca/information-systems-technology/services/faculty-service-desks> for assistance removing the root certificate. If you feel confident doing this yourself, removal instructions can be found at  https://filippo.io/Badfish/removing.html.
