“Tricks for Defeating SSL in Practice - Moxie Marlinspike”

Recommended talk on defeating SSL in practice

Full comment

This guide is very hand-wavey. Tor alone is a poor operational security strategy; using nikto and unix-privesc-check does not a hacker make. This may be a decent place to begin one's inquiry, but don't let it end here too.

“Moxie has an entertaining talk”

Entertaining talk on certificate attacks

Full comment

We don't have humans in the loop for issuing certificate; this can and has been exploited for fun and profit, with fun attacks like getting a cert for "citibank.com\0.mydomain.com" which used to trick the C strcmp in most browser certificate checking routines. Moxie has an entertaining talk: this video Your problem would be getting people to "thecitibank.com." Chrome, Firefox, and GMail would all eventually figure out it was a phishing site and warn users about clicking through to it.

“Perhaps one of the techniques discussed here”

Possible techniques behind public WiFi attacks

Full comment

Perhaps one of the techniques discussed here: this video ? Or, as this was published a couple of days ago, it might have utilized POODLE, or even BEAST in unmitigated cases. But yeah, I'd also believe user error in some cases.

“was presented by Moxie Marlinspike at Black Hat in 2009”

Original sslstrip presentation at Black Hat

Full comment

If it helps, the attack you're describing is called sslstrip and was presented by Moxie Marlinspike at Black Hat in 2009: this video (code here: link ) As others have mentioned, the current best defence against this is HSTS (and, in particular, HSTS preloading). I think the best explanation of it is here: link

“The only effective way to get guaranteed security is with HSTS preloading.”

History of the stripping attack that HSTS preloading prevents

Full comment

History lesson incoming: this video The only effective way to get guaranteed security is with HSTS preloading. Anything short of that leaves you vulnerable to the linked attack, which dates way back to 2012.
