This thing Facebook did โ€” running an MITM on Snapchat and other competitorsโ€™ TLS connections via their Onavo VPN โ€” is so deeply messed up and evil that it completely changes my perspective on what that company is willing to do to its users.
@matthew_d_green How does that even work? They should get a certificate error when someone is trying to do a MITM.
@andytiedye VPN installed a new root cert

@smn @andytiedye Is this really how it worked? ๐Ÿคฆ

I have said 100 times and been ignored: device & browser vendors need to remove custom root CA support from their mainline products for consumers and only offer the antifeature in a $1000+ enterprise product.

@dalias @andytiedye that's what was initially reported but I've now also seen claims that snapchat started cert pinning prior to when this VPN thing went live so now I don't know. Maybe it was more sophisticated?
