comment Why are web servers ubiquitously configured by blacklisting inaccessible files instead of whitelisting the accessible ones?
@Iszi harder than maintaining security-hole-free blacklists? As someone who has made and maintained both, I have to disagree.

comment Can I scratch off the magnetic strip off a debit card to only allow chip and PIN?
What @tylerl said, because otherwise you wouldn't be able to use the card online. Having said that, we really need to fix this, e.g. with 2FA (e.g. send a text message that requires a respone for card-not-present transactions).

comment What risks are introduced by the browser passing the “referer” to the next site visited from a link to another domain?
A privacy fix would not have to break this: the Referer header could still be supplied if the destination is on the same domain.

For the record, this is no longer the question I asked; it's been edited and became a different question.

So it's a privacy concern that's trivial to address, but isn't being addressed. Why is that? Do the users of the browsers want it? Or is this feature mainly there for the benefit of those who run websites?

comment How to encrypt entire HDD without any password prompts?
I'll be quite happy to store the key on the system drive, which isn't encrypted. My use case is apparently the top answer to "what are good use cases of disk encryption" - so how do they do it? I agree it seems unusual, but this use case was the top answer there...

comment How to encrypt entire HDD without any password prompts?
The broken drive is too broken. Click of death. Doesn't mount. The data I don't care about; it was a full mirror of another drive. The manufacturer explicitly recommends I wipe any data I don't want leaked before I send it for warranty replacement.

comment Why wasn't heartbleed fixed before?
Keep in mind that there exist programming environments in which this type of bug (unsafe & unchecked memory access) is essentially impossible, although they suffer a performance penalty (of various significance) as a result.

comment Should websites be allowed to disable autocomplete on forms or fields?
Nice to have someone I might call an "insider" here. Suppose Firefox were to unilaterally throw away this option "by popular user demand", ignoring the opinions of banks. Do you reckon Firefox risks being outright blocked by banks in this case based on, say, UserAgent? (obviously circumventable, but not by non-tech users).

comment Are secret URLs secure over HTTPS?
Do any known browsers send HTTPS URLs to third parties, ever? For example, Firefox crash reporter, or Chrome search-as-you-type, or IE's malware protection service?

comment Are secret URLs secure over HTTPS?
@Timwi nor is there anything in the HTTPS protocol preventing Chrome hosting a remote desktop server and uploading all your passwords to a third party; that's not the point :)

comment Are secret URLs secure over HTTPS?
Related: Can URLs be sniffed when using SSL - but different; that question is about the data contained in the request, not whether the browser leaks it through other channels.

comment What are the security implications of people downloading addons, wrongly thinking that they are safe?
@Piskvor Yeah, those UAE prompts totally train users to ignore them. Where's the "I trust this particular program; don't warn me again unless it changes" button?...

comment Is this phishing or the real PayPal?
I've also seen paypal.com redirect me to paypal-business.co.uk, which gave me quite a shock a few times. It's like they're trying to look like a fake...

comment Establish a secure channel with mutual authentication given pre-shared public keys
I was hoping that since Diffie-Hellman with pre-shared public keys is mentioned in at least one source, it's at least somewhat analyzed by experts, or maybe even implemented...

comment What prevents people getting charged over NFC in crowded places?
@SomethingSmithe It wouldn't be unlike banks to do this just for the show, whereby there's no real cryptography going on. (where the bank could verify that the user actually provided the pin to the reader).

comment Are there any nice info sites dedicated to explaining how and why to (not) store user passwords in the database?
I especially like the first one.

comment What can I do if my bank thinks my date of birth is “known only to me”?
@LucasKauffman Before I name one, I guess I should double-check that they would actually execute a money transfer over the phone with just DoB + postcode. They give out the balance and cancel cards with just this much, but that’s not as sensitive as withdrawals.

comment What can I do if my bank thinks my date of birth is “known only to me”?
I doubt that enough people will do it though; this requires someone with a huge social network and a lot of influence to do a move like that. Or someone with enough money to take out that the bank actually gives a damn... at least a few million, I reckon.

comment What can I do if my bank thinks my date of birth is “known only to me”?
@GeorgeBailey They’re replacing the 3D Secure system, which, in case you aren’t from a country that uses such a thing, is basically something that asks you for a password before authorizing an online card payment. This was already known to be very insecure (pdf) so the change isn’t that significant. Separately from that, my bank has always allowed me to "log in" over the phone with nothing but account number, date of birth and/or postcode.
