So, this is how any of us who are concerned about security operate. We don't put in a user name and password unless we see that green lock, click on it, and it says we're talking to who we think we're talking to. This is because of a hacker technique called DNS poisoning, where hackers can manage to convince your local name servers that their server, not the real Google.com's web server, is where you should go to get to https://www.google.com. They then intercept the user name and ID that you enter. Well, they can convince your DNS to give the wrong address, but they don't have Google's private key, so they can't impersonate Google. So you won't get that green lock. But they hope you won't notice. You should.
This attack is called phishing, and is used to filch your user name and password, which are then used in an automated fashion on other web sites. Usually after your DNS is poisoned, you get an email telling you to go to http://some.web.site.com because your password is expiring and your account will be deleted. So I got what looked like a phishing email from Fedex.com saying that my account was going to be deleted because I hadn't logged in for over a year, unless I logged in within the next two weeks. This actually would be normal for FedEx -- the only reason to ever log in to their web site is to set up your notification preferences that tell you that a package is on the way, has been delivered, and so forth. So with the possibility that it might actually be a valid email, I manually type https://www.fedex.com into my browser's URL bar (*never* click on a URL in email! Never!), hit the ENTER key... and immediately got kicked out to a non-encrypted site.
At which point my reaction was, "WTF? Have hackers hacked the FedEx web site and are grabbing user credentials?" But it appears that's not the case. Using the host and whois systems to resolve the IP address, it goes into Akamai's site acceleration service. Instead, it looks like pure rank incompetence. FedEx is deliberately putting their customers' user names and passwords at risk because... why? Well, because they're too stupid to know how to implement SSL in an Akamai-distributed architecture, apparently. Despite the fact that Akamai has explicitly supported SSL for years.
So anyhow, I use LastPass so my password was random gibberish in the first place, so after examining the source code of the web page to see if there were obvious problems, I logged in. At that point the web site did put me into a proper SSL-encrypted web page. But the point... the point... I should have never had to enter my user name and password into a plain text unencrypted web page in the first place. There's no -- zero -- way to authenticate that you are actually talking to the site you thought you were talking to, if you're talking to a web site that's not https. DNS poisoning attacks are ridiculously easy and could have sent me *anywhere*. The only reason I felt even halfway safe talking to this web site was because LastPass had generated me a random gibberish password for this web site a year ago, so if they *did* steal my FedEx credentials, at least they could only be used to hack my FedEx account, which would be no big deal (I don't have credit card information or billing information associated with the account, it's strictly an informational account). But still. Bad FedEx. Bad, bad FedEx. Bad DevOps team, no cookie, go to your room!
The takeaway from this:
- Check those green locks. They're important. It tells you a) whether you're talking to the web site you think you're talking to or not (if it's there, you know you are, if it's not, you don't know), and b) tells you that any user names and passwords that you enter will go to the web site via an encrypted connection.
- Any web site that your company provides should only ask for user names and passwords on an SSL-encrypted https page. If someone tries to go there with a plain http: url, it should immediately be forwarded to the SSL site.
- If you don't follow that last rule, you will be publicly shamed, if not by me, by someone. And a public shaming is never good for your brand.
- Furthermore, if you don't follow that last rule, there's many potential customers who will simply refuse to use your web site. This perhaps is not a big deal for FedEx, since most of their customers have no choice but to use their web site to schedule package pickups, but if you're providing a web service to the general public? Dude. You are leaving money on the table if you do something stupid like ask for a username and password on an unencrypted page.
