Stripping SSL and Sniffing HTTPS using SSLstrip

Post by Dukeswharf »

Just came across this video. Is NoScript able to counteract this?:

Yes.
Manual HTTPS enforcement and HSTS are meant to protect against this kind of attack.

Note that HSTS is not able to protect against this attack when the very first request to a site is over a MITMed line.

Where "very first" here means "very first in the whole browser's lifetime", which is very unlikely, i.e.:
  1. You're connecting from a workstation which is not yours (equally dangerous, since it may be keylogged) or
  2. you're registering yourself for the very first time to a confidential service from a public or otherwise hostile network
