Ask Slashdot: Why Do Firms Leak Personal Details In Plain Text?
An anonymous reader writes "Having entered my personal details (full real name, home address) to websites with an 'https://' prefix in order to purchase goods, I am still being sent emails from companies (or their agents) which include, in plain text, those same details I have entered over a secure connection. These are often companies which are very keen to tell you how much they value your privacy and how they will not pass your details on to third parties. What recourse does one have to tell them to desist from such behaviour whilst still doing business with them if their products are otherwise desirable? I email the relevant IT team as a matter of course to tell them it's not appropriate (mostly to no avail), but is there any legislation — in any territory — which addresses this?"
The reason you get emails with your personal information has nothing to do with https (secure) v/s http (insecure), it has to do with the company you did business with sharing/selling your information with their 'business partners' and / or selling it to marketing companies, and the tracking cookies from other websites you've visited.
Linux is unix training wheels, while BSD *is* unix.
People are waaaaay too paranoid these days. There is nothing sacred about your name and address. No one can steal your identity with it. If the email had your SSN or DOB in it, that would be different. But your name and address? If you have a landline phone, it's probably in a phone book and on numerous telephone directory websites and has been for years. Public court records have your name and address too. Nobody cares.
I believe that his point was that the exact information that was sent encrypted is now being sent in plain-text over email. So, what's the point of using HTTPS to send private information if it's leaked right back through plain-text on port 25, and what can be done to tell companies to stop forwarding all those details through emails. Maybe they could email a link telling the user where to log-in to see his invoice instead of forwarding all his private information through email.
Why should they care?
There's no benefit to them keeping your information safe, it costs them time, money, and effort to do so, and there's no real consequences when they screw up. They will just put out a statement saying "all of our customer information was stolen, we recommend everyone change their password, and the hole is now patched - it can't happen again!".
Also, they can blame the thieves. "It wasn't our fault, it was that scoundrel who noticed that you can change the account number in the URL to get into someone else's account."
As to "we value your privacy", what does that actually mean? It means that companies have discovered that people trust companies that make that statement, and are more likely to purchase from such a company.
That's all it means, and no more. It doesn't mean that they care or that they abide by the statement, it means that they think they can get more business by using that phrase liberally in their public-facing documents.
You're living under the naive assumption that companies mean what they say and will do what they promise. They do what the consumer protection laws force them to do - any statement that reflects these laws is probably true, while the rest is simple puffing.
So, what's the point of using HTTPS to send private information if it's leaked right back through plain-text on port 25
A locked front door and an open back door is better than two open doors. Although yes, they should lock the back door. What we really need is industry-standard secure-ish email.
It's just like some fool sending you an encrypted archive with the password in the same email. It looks cool and they don't know how much of a useless waste of time it is. The actual gatekeepers only get the superficial cargo cult appearance of security from the people that should be the gatekeepers, but that's seen as OK since you'd need to employ somebody to do it all properly. Putting on a show is cheaper.
The question is, who are you worried will find this super secret sensitive information (Your name, address and fact you use the site)?
The government? They don't need to intercept the e-mail they have easier ways of knowing it?
Some criminal targeting you specifically who manged to intercept this e-mail? He already knows who you are all he learned is you use this site,
simply seeing the IP is enough?
Some random script kiddie on the internet? intercepting e-mails is not that easy, yes they are in plain text but they are not broadcast over the internet for everyone to see
you have to position yourself along the route it travels (and this route normally doesn't change much) and attack somewhere along it, not impossible but hardly effortless. and why would he?
Which only leaves corporate espionage targeted against the site you are visiting, which though more likely then any other vector still seems a bit far fetched, and in the end all they learn is your name&address.
There are plenty of serious threats out there on the internet, this doesn't seem like one of them.
focus your worrying else where.
Says "Anonymous Coward". :P
Generally speaking, retail sites (Ones who have the really important information, like credit card numbers and the like) also only store hashed passwords. So asking for a password will get you a temporary link e-mailed (usually requiring further security questions) to set a new password. Other personal information, your name and e-mail address, are not considered worth securing, as you automatically send them out with every message you send, and all your mail is invariably addressed to you with your full name by your other contacts.
Postal addresses are generally something of a grey area. On the whole, they're not particularly secured (Anyone who was determined to find out could find your address from the phone book, electoral roll, or other public list). Credit card numbers are typically secured by removing/obscuring all but the last 4 digits, and items ordered are again typically treated as "Better to include with a receipt, as a double-check, than to exclude".
There is, as always, a fine balance in the "Privacy is required" to "more information is better" debate, but leaving that aside, while SMTP is a plain-text transfer medium, it generally requires quite a lot of work to actually get someone's details. For instance, you have to:
This isn't easy, or practical. Sure, if you want to, you can do it, but what is the point? If you're stalking them, there's much easier methods (going through their trash, trawling public records, google searching their name). If you're selling to them, there's easier ways (Buying details lists from credit bureaus, mass mailing).
The problem of secure e-mail has been around for a long time, and many solutions have been proposed for the problem (S/MIME, PGP, Domainkeys), but it's largely a chicken-and-egg problem - Secure mail systems are not universally supported, so it's not used/Secure mail systems aren't used, so they're not supported. Solving this problem is left as an exercise for the reader. Obviously.
Or explained even easier. It's profitable.
Help stamp out iliturcy.
HTTPS means that you have a securely encrypted connection with the remote server. Not that the people who own the remote server are going to keep your privacy sacred.
But it does mean that nobody on the path can listen in on the connection. Which is defeated if then the same info is sent back over an unencrypted channel.
In those places, a $100 bill would work as well or better than a passport for getting through checkpoint guards. The idea that someone would bother with your passport number in trying to forge a passport to get through there is rather laughable, since they didn't even bother to check said number to see if it was legit.
At a border with better security? Not going to work. Passports have a lot more security to them than that, particularly now.
Basically if places have weak security, the have weak security. Someone isn't going to bother to try to get a legit name and number to forge a passport. If they have tight security, then it wouldn't do any good as they check the other features, which wouldn't match.
and his solution is to mail the IT department at the company, like the PHB there gives a fig (or possibly even understands the problem)
When he should do is mail the legal department instead, or failing that the CEO or CIO. They might not understand the situation either but they'll understand the words "privacy" and "violation" and sit up, then they'll pass the blame on to the IT PHB and he'll have to "just fix it" in some way. Which he will do by getting an underling to remove most if not all of the personally identifying information from all emails in a overly-broad way, until the Marketing department decides it needs to put your address on every email all over again.
