Subject: Ernst & Young audit overlooks Phorm's violation of its own privacy policy
Message-ID: <3GyeX7C1lwkIFAtf@highwayman.com>
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I've been looking at deep packet inspection / targeted advertising
company Phorm for the past couple of days and have found a clear and
simple case of Phorm violating its own privacy policy in
contradiction to Ernst & Young's audit of the company's systems.
etc...
I recommend reading the whole article :)
For some time I (and others) have been pointing out that the Phorm ID
can be obtained by any website that is visited (the Phorm system will
attempt to remove it, but cannot succeed if the cookie value is
transferred by https). This could lead to a trade (illegal under EU law
of course) in matching Phorm IDs with other data...
Hal Roberts has taken this further by pointing out that this explicitly
infringes Phorm's own privacy policy -- as audited by Ernst and Young !
He does ask "How did Ernst & Young not find this problem?" and discusses
the shortcomings of the audit process generally.
However, one of the reasons that occurs to me is that when Ernst & Young
audited the system it worked differently! We know that it used to use
HTTP Referrer fields (because they leaked data into logs all over the
Internet) ... but then Ernst & Young don't mention that failing either,
so maybe Hal's meta-analysis is all that really matters:
But the report is completely opaque, so all we have to rely on is
Ernst & Young's reputation. For that reputation to be valid, though,
there has to be a strong feedback mechanism that discredits Ernst &
Young when it produces a faulty report. In practice, what's that
pushback? Is there any history of such audits being disproved to the
disparagement of the auditing firm? In the face of only a vague
threat of some sort reputation loss, the strong, direct incentive to
produce positive reports to generate more business will win every
time.

Anti-terrorism, Crime and Security Act: Voluntary Retention of Data
The Earl of Northesk asked Her Majesty's Government:
How many grants they have given to telephone companies and internet
service providers to assist them in the voluntary retention of data
under Section 106 of the Anti-terrorism, Crime and Security Act 2001;
and what has been the total annual value of such grants in each year
since 2001. [HL4469]
The Parliamentary Under-Secretary of State, Home Office (Lord West of
Spithead):
Payments under Section 106 of the Anti-terrorism, Crime and Security
Act 2001 (ATCSA) commenced after the code of practice for the
retention of communications data was approved by Parliament in 2003,
the first payments being in financial year 2004. In October 2007, the
Data Retention (EC Directive) Regulations 2007 came into force and
many former ATCSA grants payments are now made under those
regulations.
- -=-=-=-=-=-
If you think this doesn't especially fully answer the question then
you'd be right!! Lord West (actually of course someone less senior)
dropped part of the answer between the his front door and the House.
Expect more soon :)

Message-ID:
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Despite suggestions that the Communications Data Bill is all about
implementing the Data Retention Directive (and not about black boxes in
ISPs, centralised storage of comms data and so on), it turns out that
the Home Office will be using a boring old statutory instrument to bring
the Directive into effect (just as they did with the telcos last year).
Expect a consultation Real Soon Now :) and the draft Bill to be
delayed...
However, Lord West seems to think that it will all be in force by the
1st April next year, which Brussels may be disappointed about, since
their deadline is the 15th March!

The Earl of Northesk asked Her Majesty's Government:
In light of the transposition of the data retention directive
(2006/24/EC), as applied to telephone networks, into United Kingdom
law by secondary legislation (SI 2007/2199), what plans they have to
make similar provision in respect of the directive's application to
the internet; and, if there are no plans for such implementation, how
they intend to give legal force to these elements of the directive.
[HL4464]
The Parliamentary Under-Secretary of State, Home Office (Lord West of
Spithead):
In October 2007, the Data Retention (EC Directive) Regulations 2007
came into force, completing the initial transposition of the European
data retention directive. We plan to consult publicly before
transposing the remainder of the directive to come into effect on 1
April 2009.

Thanks to Mary for the link, but not that big a contract, which is in

But I heard on the radio that 3 contracts have been let - anyone help

So each grant is of the order of 700 grand. It depends on if the
grants are capex one-off, capex on a depreciation basis or capex+opex,
but for half a million quid a year over three years you could buy and
operate a substantial fraction of a petabyte of disk in a MAID arrays,
and a few hundred terabytes of conventional RAID (the power would get
you).

Quite so. One of my personal bugbears is people who claim to be
compliant to a standard, but don't hold registration. If they're
compliant, it shouldn't be hard to get registered. If they can't get
registered, they aren't compliant.
Moreover, it's one thing to be compliant on a given day.
Registration carries with it an obligation to surveillance audit
(twice per year in our case) and part of that audit is in turn an
examination of the internal audit. People who claim unregistered
compliance simply don't have that.
We thought we were 27001 compliant. When the time came to actually do
the work, we found that there were a whole host of things that we
didn't do completely, that seemed trivial, but were actually hugely
beneficial. As an example, correctly functioning management
reporting. As another, robust measures of effectiveness.
My next task is 25999, and again I've got agreement that although the
driver is customers who want ``aligned to'', we're actually going to
do registration. Partly because registration means you're on the
front foot whenever the legitimacy of your management system is
questioned. But mostly because if you're not registered, you're just
making bold claims.
But we're on the same page: 27001 doesn't prove an organisation has
effective security, although it does prove that at least they're
making some effort. Absence of 27001 however pretty much proves they
don't care and can't be bothered.

In 2004 each grant was of the order of 16K... so what you're seeing is
MUCH larger entities obtaining money for data retention.
Note that this is in the run up to the time when the mobile companies
and telcos had to move to retaining data for a year; whereas one might
suspect that 2004 was all about tiny little ISPs ...
... since I have no inside information :) I can speculate along with
everyone else :)

capex one-off I believe -- again speaking from informed ignorance :) ...
I believe that the opex is supposed to be covered by the "per request"
that the authorities pay for making their 500K requests/annum.

we're now sending 1.5E9 text messages/week... if you need to record
time, date,
source number,
destination number,
geographic location of source and destination
and the byte-length
(but not of course the content!)
then that starts to mount up... and that's before counting phone calls,
both fixed and mobile

Whether they do, or have the capability to do so and whether they
actually do it to every single traveller are different questions. I
would guess they are certainly capable of copying the data, but making
a mirror image of a hard drive is a lengthy process (due to slow
platter to cache transfer speeds, remember that the interface speeds
that the manufacturers state are only disc cache to bus transfer
speeds). Having said that, you possibly won't be able to prevent them
from having a good browse and make copies of whatever they feel is
relevant, especially if they have nothing better to do with their
time.

Don't take your data with you, you can always pull whatever you need
from your corporate net when you're there (in the States) - treat the
data on the 'need to have now', instead of 'can have whenever', basis.

Probably about 4TB per year for the CDRs, 16TB per year if you wanted =20=
to store the messages as well (although they're not all 160 bytes and =20=
the text will compress). For voice and mobile, were I in the office =20
and it not 0045 I could get the volumes from our regulatory wonks, but =20=
as a rough guess let's size it for 100m subscribers each making 10 =20
calls per day, so 7E9 CDRs per week each of about the same size, so =20
perhaps 20TB/year. Can we agree to a total of 40TB/year to store all =20=
CDRs for voice plus the full text of every SMS plus 10% for luck?
The underlying cost of the storage is around $1000/TB (based on an EMC =20=
AX4 SATA array). None the less, if you gold plate, replicate, gold =20
plate again, plus government mark up, have twenty consultants dance =20
around the rack, you're not going to spend more than =A35000/TB capital, =
=20
and as you can put the a couple of hundred TB your operating costs =20
will be trivial once you've paid for the electricity (about 50W/TB, so =20=
say 1kWH/day/TB).
So you can buy 40TB usable (say 80TB raw if you're replicating) for, =20
at the absolute, ludicrously inflated, maximum of =A3200K (I bought 40TB =
=20
a couple of years ago, based around 500GB SATA spindles, plus some =20
exotic NAS heads and a load of replication software, and it cost less =20=
than half that, so my contention that =A35K/TB includes replication =20
seems reasonable), and it'll cost at the outside =A34K/year to power --- =
=20
that's assuming no spin-down, which is obvious nonsense. It'll fit =20=
in half a rack.
So why all the extra cash...?

AIUI they now reserve the right to take away your laptop
*indefinitely* and pass it onto *anyone*, so the fact that copying the
data is laborious is irrelevant. (Please correct me if I'm wrong

Travel with a freshly installed laptop. Upon arrival, plug into hotel
DSL and download the data you need over your VPN. Prior to departure,
wipe the data to your preferred standard (ranging from nothing, if you
trust your home customs people, through to physical destruction of the
disk, replacement of disk and re-installation from a DVD you
downloaded and burnt when you arrived) and return with a clear
conscience.
Or just take a thin client and access your company network via
Citrix / X / VNC / etc.

The phone companies love to make profits. They charge the cops
exorbitant sums for wee bits of data like a day's cellsite
tables. So I'd factor in very large greed multiplier, which may
confound a simple data assessment.
[This is based on experience, by the way. I've done many cellsite
analysis cases in the last five years, and a fair number of times the
amount of data acquired has been minimised not for human rights
reasons but because of the impact on the bottom line of police budgets.]

AFAIK it's genuine, and quite ironically the US is rumoured to have told US
businessmen to be aware that foreign powers, especially China, may copy
their data at border posts, according to The Register:
http://www.theregister.co.uk/2008/07/21/cyberspy_olympics/
"Last month the department of Homeland Security privately warned government
and key private-sector contacts of the cyber-security perils facing overseas
travelers from foreign governments. Spying techniques outlined in the
advisory, which wasn't made public, included copying the contents of laptop
hard disks at border crossing or in hotel rooms"

That may set the price that a telco might demand for discharging its
legal and regulatory obligations. It doesn't, however, set the price
that the government has to pay (which could, in fact, be zero). It
would be interesting to know how the eventual payment --- which should
just be cost recovery --- is arbitrated.

I think it's fairly safe to assume the grants are not just for storage.
This leaked BT network diagram on The Register (re: Phorm) shows Passive Tap
devices, which I assume would be used for legal wiretap of an IP steam and I
can't see the ISPs stumping up for the cost of this architecture themselves.

interception capability is paid for under s14 of RIP 2000 -- and I am
not aware of any published figures about that... or indeed whether the
conventions would allow a PQ on the topic
>http://regmedia.co.uk/2008/02/29/architecture.jpg
the impression has been given that Phorm is paying for the installation

By ``passive tap'' all it probably means is a mirror port on a
switch. Hardly high-cost.

But scaled up to handle 10m connections, with configuration, audit etc. The
mirror will only be for single authorised connections, which need to be
cross-referenced against the account holder to find the current dynamic IP
(if done at IP level).
The cost will come in the size, scalability and configuration of the
solution, not the cost of the raw equipment.

As one data point, I recently entered the US to go to a conference and
noone even asked whether I had a laptop (unlike arriving in Canada, when
they did). Mind you I may have confused the Americans by immigrating by
train!
There were quite a few delegates around the conference who had brought
'vanilla' laptops and were using one of the methods suggested by others
on this list. On the other hand I think those people/organisations were
always quite cautious about travelling with company data.
And presumably if a customs person at the border insists on having my
laptop as a condition of entry, I could always change my mind about
wanting to enter?

By air, I would have thought that such a decision wasn't
desirable/possible on the grounds that you can't catch a flight back on
your own without first going landside, and if they are going to have to
escort you staying airside (and getting a ticket/boarding pass etc)
that's sufficiently inconvenient for them that they could easily decide
they were going to search you anyway.
I doubt it would have a happier outcome by train or car.
This is unlikely to be a particularly USA thing.

It's all very well discussing the theoretical rights and wrongs of this
policy, but the fact is that AFAICS it's always been the case that if
you are crossing a border you and everything you are carrying are
subject to inspection by both customs and immigration. Arguing about
whether they have the right to examine your laptop seems to me about as
sensible as arguing about whether they have the right to grill you about
where you've been and where you're going. It may be unpleasant; it may
even be unconstitutional. But the reality is that the average tired,
stressed-out traveler faced with people with the authority to put him in
jail is going to feel threatened enough to comply whether or not the
policy is legal. As a *practical* matter I think one must assume that
*all* national customs officials have this power. And although I agree
that a laptop feels like an extension of your brain, it would be
illogical and unlikely for a customs officer to do a strip search and
then wait for a court order to check the contents of your laptop. If
they suspect you and want to examine you, ISTM that rightly or wrongly
you are at their mercy.
See also people whose cars have been taken apart at the Canadian border
by inspectors looking for drugs. They don't have to put it back together...
I'm not saying it isn't scary; obviously it is. (As is the US's
statement that it can impound your written notes, etc. - as someone who
makes a living from the contents of my brain as scrawled all around me
on pieces of paper, both physical and electronic, I find the prospect of
having it all removed extremely alarming.)

As far as I am aware, the authentication is actually done by your bank, the
transaction being proxied by the Verified by Visa architecture.
The architecture and mechanism is called 3D, and the issuing bank must
support a 3D Secure interface.
Google of 3D and Verified by Visa may yield more details.

The reflects my experience; but if the authentication fails to recognise
my password (or the required characters from it), it merely requires me
to reset it, and then accepts the use of the reset password. So not
very stringent.
(In fact I think this may reflect the corresponding Mastercard process,
rather than Visa; but same difference probably.)

They point to a webage that describes the scheme, which does give
"account management" options to change the VbV password (aka shared
secret), but it seems likely from their description that the two are
inextricably linked and changing one changes both. That's one reason
that perhaps the VbV system is "franchised" with the query being done in
realtime back to the bank every time I make a purchase.
Or is the *whole* Visa scheme just a franchise, with merchants having to
have a credit-authorising dialogue with the relevant bank rather than a
central Visa-branded clearing house?
With CC data theft headline news again today, I just feel I'd like to
know *where* my data is being held.
If the mechanism's suitably secure, then having the same password might
even be an advantage, as it's one fewer thing to have to remember.

Hmm. It's so long since I was directed to sign up for VfV that I can no
longer remember how it was done, but I *know* I chose my own password
for it.

Which would imply yes, that banks do it differently from each other.
Mine is on a Barclaycard, if that helps.

What frosts me is that adding VfV to the list of hoops you have to jump
through to put through a purchase doesn't make the bank any less likely
to decide the transaction is dubious and stop your card.

But the nail has been hit on the head! Luckily, my "memorable name" is

the scheme of sharing this password between different functions is a bit
odd.

There's also the advice to "never volunteer information" as it might get
you into an unintended scrape. Hence, apparently, the answer to a
question "do you have the right time" should be either "yes" or "no" and
not "ten minutes to two" because the latter might not be correct.

There's the other aspect which is that if the transaction is rejected as
"suspicious" (not because any of the passwords were wrong, just a
purchase outside what they say is your normal pattern) then they don't
tell the cardholder that their card *may* have been compromised. Which
is odd because surely the only plausible scenario that it's "not you"
making the purchase in such circumstances is that the card *has* been
compromised, and shouldn't you be warned?
> and stop your card.
IME they just refuse the charge, but don't do anything else, and
especially don't stop the card, or issue a new card proactively.

Whereas if you speak to the departments inside telcos doing the daily
work, they make a loss in terms of the profit-centre calculations that
are done. Scraping some numbers from a database "for intelligence
purposes" is one thing, but putting it all into a form that's acceptable
to a court as evidence may be another.

It's not a cookie issue - I've also tried it with a browser that accepts
cookies. Nor is it a log-in issue. I suspect their website's broken :(

I subscribed long ago to the corrresponding MasterCard scheme. It all
seems to me to be pretty secure - the only problem being that very few
merchants have yet agreed to implement it, so you still run the usual
risks when using such merchants.
The other oddity is that they (Natrwest/RBS in my case) have outsourced
the operation to a gang called CYCOTA somewhere in San Francisco, and it
is the CYCOTA certificate that you see when you make the secure website
connection. So I have to assume (and IMO it is a reasonable assumption)
that CYCOTA are running a properly secured outfit (i.e. at least as secure
as Natwest/RBS, and surely more secure than Amazon and the like).
The way it works is this. When you give your Card Number to the Merchant,
and they attempt to verify it through the usual channels, they get told
that the card is signed up to VbV (or rather the corresponding Mastercard
thing). They then transfer you to the CYCOTA site (whose certificate you
then see) and you negotiate with CYCOTA using your
password/secrets/whatever (quite convenient actually, because they exhibit
your secret to you, to prove that they know something that the merchant
does not know, but you know that they know; so you can choose the secret
in a way that reminds you which of your various passwords you need to give
them). When they are convinced you are who you say you are, then they
inform the merchant accordingly. Your passwprd, secret, etc never go
through the merchant's site, and you do not have to disclose the magic
number on the back of the card.

But to go back to my original question, presumably you *are* disclosing
it to CYOCOTA, and maybe they have a copy of everyone's secret so they
can check they match. Or does CYOCTA contact each cardholder's bank in
real time with a copy of the secret asking "does this match"? And
hopefully throwing away its copy of the shared secret afterwards.

Yes. CYOCTA and Verified by Visa are only the conduits for merchants. They
work out the issues using the first 4 digits from the card and proxy the
authentication.

As if by magic, a story published in The Register today:
Net shoppers bullied into being Verified by Visa
http://www.theregister.co.uk/2008/08/07/verified_by_visa_compulsion/
"When shoppers make purchases online with participating retailers they are
typically taken to a website run by the card-issuing bank, where they are
asked to submit a VbyV or SecureCode password to proceed with the purchase."

I think you have to trust CYCOTA to the same extent that you trust your
Bank.
I think (from what I remember) they hand you over to your Bank if you
claim to have forgotten your password, but I do not know whether they
interact directly with your Bank for each transaction. (Actually, a
sensible implementation would be to keep a cache of data for frequentlky
used cards, and to contact the Bank in other cases).

Yesterday's articles - start at:
http://www.timesonline.co.uk/tol/news/uk/crime/article4467106.ece
and there are two more articles linked to that - pointed out that there
are two stages to the protection, and only one has been broken.
The other stage involves a global public key server, so how long before
a bogus key pair is generated and the public key inserted into the server?

This isn't only recent, though. The Telegraph during its Connected

In my experience they call me and ask me whether the transaction was
originated by me. If I say no they stop the card and send me a new one
(with a different number, of course). If I say yes they don't stop the
card.
If they can't contact me quickly they go into a spin, trying to contact me
by all sorts of routes.

It's a franchise, but there are multiple providers. I'm not clear on

VbV can be integrated with other risk analysis tools. Whether or not
a given bank chooses to implement this level of sophistication will
depend on their mitigation strategy for fraud losses.

The phone companies love to make profits. They charge the cops
exorbitant sums for wee bits of data like a day's cellsite
tables. So I'd factor in very large greed multiplier, which may
confound a simple data assessment.
[This is based on experience, by the way. I've done many cellsite
analysis cases in the last five years, and a fair number of times the
amount of data acquired has been minimised not for human rights
reasons but because of the impact on the bottom line of police budgets.]

This is my experience with Barclaycard. However, *meantime* they block
any further transactions, and usually this happens before they've
contacted me, so I don't know what's going on.

I don't really follow the earlier assertion that the batch of stolen
passports was "worthless" (without the chip being properly programmed).
Who has a reader for them anyway?
The last return flight I went on, although my passport was checked by
immigration officials each end who might have, the airlines who are
supposed to check that the right people are getting on the plane [1]
failed at both ends. At the departing gate the girl didn't look at my
passport, coming back it wasn't even opened.
[1] Reporting details of passengers in advance is useless if different
people get on board.

That's interesting, because I hadn't found anyone with a *refused*
charge that had happened to. Sometimes with accepted but unusual
charges.

What worries me about this whole thing is that the card companies want
us to keep the secrets secret, and then invent ways that to a casual
observer might appear to be leaking the secret to third parties. So who
else might they think we are supposed to know to trust?

I have come across an interesting and potentially quite unpleasant
pair of features.
The RBS is one of the banks at which I maintain an account, and as
with my other banks I've been very careful not to set up a password
with them for phone and Internet banking, because of the liability
transfer that gets kicked off (see Bohm, Brown and Gladman).
Last week their credit card people wrote to me asking me to call them
at once to verify a suspicious transaction. I did so and the lady at
the call centre demanded my password. I explained that I had been
careful never to set one. She brusquely contradicted me, told me I'd
set one, said it might be my mother's maiden name, and told me 'its'
first and last letters - which were indeed the first and last letters
of my mother's maiden name. I protested and she said she would not
speak to me any more as I 'had refused the security questions'.
It looks like the RBS has decided to deal with the refuseniks and the
can't-be-bothered-niks by simply giving us all passwords, whether we
consented or not.
The second disfeature with the RBS is that when I attempted a few
weeks ago to use one of their cards to buy a ticket from Easyjet, the
Easyjet website insisted I pick a password for their equivalent of
VbV. I phoned their call centre and asked if I could get a card that
did not have this feature enabled. Not even the supervisor to whom I
eventually spoke seemed able to understand what I was on about, let
alone help. People who use their Coutts brand seem to have better
luck but speaking to someone who understands the bank's own systems
doesn;t seem to be an option for us proles.
It really does seem like a race to the bottom, doesn't it? Pretty
soon we'll all be asked for our mothers' maiden names whenever we
shop, and when stuff goes wrong it'll all be our fault

This is symptomatic of my main worry in this thread. Did that lady have
your [let's assume you had supplied it previously just for a moment]
shared secret on the screen in front of her in the clear? Isn't that a
big risk. Or is it so difficult to type in a name you give them and get
it right, that they have to use the human being rather than a computer
to check it's correct?

So you *have* told RBS your mother's maiden name in some other context?

Both articles on the "cloning" of British passports show a decent amount
of flaws in reporting.
http://www.timesonline.co.uk/tol/news/politics/article4474143.ece
http://www.timesonline.co.uk/tol/news/politics/article4474143.ece
- - There was no passport cloning but "passport invalidating". And that
could only work because the British have the worst security
implementation in the passport RFID system EU-wide. That is because they
were AFAIK the earliest adapters in EU.
There is no active authentication in UK passports yet AFAIK which is
crucial for preventing cloning the data to another RFID. Works with an
embedded secret key on a non readable zone on the chip. The first info
the reading machine gets is a public key that is used to encrypt traffic.
The secret key hidden in the RFIDs hardware is used to decrypt that. So
you may get access to the data, you can copy them and put them on
another chip. But that will be discovered immediately when controlled by
a passport reader. There can't be any communication between clone chip
and machine. The clone chip does not have the embedded secret key to
decrypt the initial data. "Active authentication" is mandatory here in AT.
- similar in the "Osama" case. ICAOs "golden reader" is just a tool to
test chip _functionality_. They are introducing a wholly new standard,
so the problem is interoperability. The "golden reader" _does not_
perform security checks, it is not a passport reading machine that can
verify a signature.
If the young person with Bin Laden's image on the chip travelled to
Austria the passport would show up as compromised by the reading
machine. Bearing. an another signature than the so called "Country
Signer Certificate" from UK.
- - Here we are at the PKI/PKD question. Austrian federal printing agency
officials told me yesterday that they have long exchanged keys with the
British. A PKI/PKD would be practical to have, but the whole thing works
as well bilaterally they said.
Public keys are exchanged on diplomat channels, via couriers. Germany
showed open reservation to a PKI/PKD, Austrian officials just said they
were currently not participating and would not comment on the future.
Such a global database - hosted in Singapore - is not such a good idea,
quite many in Europe should think. Imagine if somebody managed to upload
a certificate that looked like one of the [inevitable] follow-up
certificates of - say - the Federal Republic of Germany. But belonged to
the Democrat Republic of Transnistria or somebody else?
Otherwise I am not happy at all with a technology that is based on
shortwave communication such as the passport chips. There is a very
simple, effective, cheap and dirty attack scenario possible on an
ancient analogue layer. ;)

Well I did complain to Natwest/RBS when I first saw the CYCOTA
certificate, but they did confirm that CYCOTA were their appointed agents.
CYCOTA seem to be able to go to the trouble of including the correct
bank's logo on the page they exhibit, so surely it would not be beyond the
wit of man to arrange for them to exhibit a certificate traceable to the
relevant bank. All it needs is a specially constructed key pair with short
expiry (so there is little rist in letting CYCOTA have the private key),
itself signed by one of the bank's better known keys which in turn would
be signed by the usual Verifraud clowns.
One of my complaints about the whole SSL certificate system is that you
are offered no choice of which ultimate CA the certificate relies on - you
just get whoever the site in question chose to patronize. It would have
been far better for each site to get itself certified by more than one CA,
and to present certificates from them all. Then I could safely tell my
browser not to recognize Verifraud.

Displaying relevant bank logo is simple, you just need to do a BIN
lookup, whereas masquerading as a part of someone else's domain is a
lot more difficult, especially if EV certs are involved. Incidentally,
is it an EV cert that CYCOTA, et al present or is it a plain cert,
does anyone know (none of my CC cards are 3d obsucred)?

I don't have a Mastercard, but I know Verified by Visa sends you to the
generically named securesuite.co.uk, owned by CYOTA INC. The cert is
not EV. Perhaps they will upgrade when it expires in October.
This is Nationwide's help page hosted on their site:
https://www.securesuite.co.uk/nationwide/tdsecure/help.jsp
The Demo part of the FAQ is reassuring - note the pop up VbV window with
no address bar or padlock visible!
https://www.securesuite.co.uk/nationwide/docs/demo.jsp
Also, to add to your feeling of confidence in the site,
http://www.securesuite.co.uk/ doesn't load and
https://www.securesuite.co.uk/ returns an empty page.
Maybe this is why googling for it turns up lots of people concerned they
are being phished.
A bit of googling and URL guessing turns up some other banks on it:

Plus a special commendation for HBOS and their flash demo:

Modifying C&P readers to log transaction information is not news,
because it was happening a year or so ago (and in a filling station near
me), but breaking the PINpad encryption might be. However, they may have
just tapped into the keypad contacts (supposed to be a sealed unit, but
you could replace it with a modified one if you worked hard enough at it).
Birmingham police had a dedicated bank card fraud unit at least ten
years ago.

Wasn't that about the time that the police/Home Office had the "bright"
idea of transferring this sort of investigation to the banks? If it
wasn't so serious it would be comical. The bank steals your money, the
police couldn't care less and tell you that you must ask the bank to
investigate itself.

Will quickly add that it depends on which devices you want to access =
your
email before choosing a certificate. The RapidSSL AFAIK isn't widely
supported on mobile devices, the Geotrust "QuickSSL Premium" is better
supported.

Not far off the truth, David. Twice about 10 years ago I listened to the
Brummy police talking about it to an industry group, and the police
attitude was that the bankers had deployed such an insecure mag stripe
system that they should solve the problem - but the boys in blue from
Brum carried on working at catching people for a while.
