Solving Visual Studio DEP0700 Error Under Parallels

Today I ran into a problem where I was using Windows 8.1 under Parallels for Mac, and I created a brand new Visual Studio project.  Just to make sure everything worked fine, I hit "Run" and went head-first into an error DEP0700.

This is a frustrating error as it's (by design) trying to stop you from running a project who's output is on a network share when in "Local Machine" mode, but of course, it has no idea that this network share is actually on your local machine in the first place, as a result of running in Parallels.

The simple solution is therefore to tell Visual Studio to run the solution on a remote machine, then set the name of the remote machine to "localhost". 



Easy fix to an annoying problem.

The Price Of Rushed Software For Apple Watch...

The Apple watch has caused a flurry of apps to be quickly updated to support it, sometimes successfully, and other times it would appear that it was done as part of a "look at us too" campaign by some companies shoe-horning their app onto the device.  With the rush to get software out, I am seeing some mistakes slipping through the QA systems of certain apps.  

Recently, I was contacted by one of my banks about a customer service issue, and as I sometimes do with that bank when they reach out to me, I pulled a single item off my pile of security issues and threw them a bonus bone to chew on.  (If they go to the trouble of reaching out to me, the least I can do is give them something to make themselves safer).

I raised this issue with the bank, who accidentally left "Backdoor" (their term, not mine) URL's for the iPad and iPhone in the localization strings under the Watchkit Extension for their app. 

Personally, I don't run this bank's app, but given my history in Canadian mobile banking (I've still got code in the Canadian retail banking pipeline that won't see light of day until 2016 or 2017 in everything from location services, to photo cheque deposit anti-fraud), I do keep an eye on this bank's mobile software to remain aware of the industry. 


Just to clarify for the legally minded, this isn't hacking/reverse-engineering/etc ... Hacking means breaking in or causing software to be coerced into doing something unintended, and reverse-engineering means taking software and getting back to the source to work out how something is done.  In this case, you don't need to even open/run the app, or perform any reverse-engineering...  As this information is left open, you just download the app from the Apple App Store, then open it up in Finder on a Mac and start reading what was left unprotected.  This is no more "hacking or reverse engineering" than reading the pages in a book is "reverse engineering that book".

The bank in question here can easily say "this posed no threat to our operations or customers" and they'd be totally correct... in the same way that leaving a million dollars on the sidewalk or having the entire CxO team dance naked down Bay Street would have little impact on customer privacy or be detrimental to operations - however it's still not something anyone should do willingly.  

What it does point to is a botched rollout where technical mistakes were pushed through to meet management deadlines.  Here's three reasons that led me to this conclusion.

First, URL's, in a bank app shouldn't be public.  As a bank, they're just asking for trouble when script-kiddies find this kind of stuff.   The URL's should be inside the app itself, where no class dumping tools can get to the strings (because they'd be encrypted, but whoever approved this from a security standpoint didn't understand that point when it was OK'd).

Second, from an architectural standpoint, this makes no sense as the iPad and iPhone URL's don't belong in the WatchKit extension (the iPhone/iPad does the internet stuff, not the Watch). At first glance, this looks like a schoolboy error in cut & paste coding.

Third, from a technical standpoint, this is sheer lunacy;  URL's don't belong in the localization strings file because you plug in the parameters of the language at runtime, not hardcode the URL's to the UI localization.

What we can do, is take the information that the bank provided and show what they should have done if they were doing this properly.  They should have created a function like this for the "Registration" url, and buried that in the app itself.

-(NSString*) getLocalisedRegistrationURL {
    NSString *URL = @"/olbtxn/registration/Registration.cibc?register=initRegistration&visitorId=native&locale=%@";
    NSString * locale = [[NSLocale currentLocale] localeIdentifier];
    return [NSString stringWithFormat:@"%@%@", URL, locale];
}

...then repeat this process for any other URL's that must be localised.  That's what should have been done.


Now, having said all the above, we can also take a step back from the technical lunacy and architectural nonsense, and ask if this was actually done deliberately?  

In my mind, this is the more likely scenario... 

In the above links there are instances of what appears to be a possible smoking gun in the form of "visitorId=native".  This gives the impression that under the hood, the app is doing a popular trick in the form of substituting the token flag word "native" for the value returned by identifierForVendor, which allows the bank to identify your device and track you, meaning that the URL is actually very likely being processed further in the app to do substitutions on the URL string. 

This obviously begs the question as to why they didn't substitute the locale when they've had every opportunity to do so?

I think the answer to this question would be that this is a somewhat ham-fisted attempt at casting the possible ISO locale values to force them to either "en_CA" or "fr_CA" because the backend servers don't have any idea what to do with en_US/en_UK, fr_FR, etc.

As you can guess, this problem is also easily solved... if the French language is not the user's primary language, cast the result to Canadian English:

-(NSString*) getEnglishOrFrenchLanguage {
    if([[[NSLocale preferredLanguages] objectAtIndex:0] isEqualToString:@"fr"]) {
        return @"fr_CA";
    } else {
        return @"en_CA";
    }
}

At this point, we've drawn two boxes around two mistakes, been given the preferred tracking mechanism and uncovered what looks like the hallmarks of a rushed rollout that at first glance looks like a schoolboy error and then later looks like back-end issues are being ham-fisted quickly to make deadlines... 

...all for the sake of seven lines of code.



Getting Live Environment Canada Weather Using PHP

The other day a little project I had running at home required some live weather data... Nothing fancy, just the current temptation, condition and a quick blurb for the forecast.

I had a number of ways I could've done this, but I chose to do this in PHP (for me, it was just a process that would run and put these three items somewhere else, so nothing major necessary).

The PHP code is here, just in case anyone else needs to do this.

<?php

$weatherXML = getLiveWeatherXML();

$toronto = simplexml_load_string($weatherXML);
$currentCondition = $toronto->currentConditions->condition;
$currentTemperature = $toronto->currentConditions->temperature;
$forecastCondition = $toronto->forecastGroup->forecast->textSummary;

$arrayData = array(
array('CURRCONDITON' => $currentCondition),
array('CURRTEMP' => $currentTemperature),
array('FORECAST' => $forecastCondition),
);

//Do what you want with the array here...


function getLiveWeatherXML() {
return file_get_contents("http://dd.weather.gc.ca/citypage_weather/xml/ON/s0000458_e.xml");
}

?>

CIBC Reference Number Logic - An Update

Last Saturday, I had a show down with CIBC staff over a situation that got out of hand and today I'd like to present an update.  You can read about it in full here, but the core point of the story is that CIBC were trying to harass me for money that I had every reason to believe they already had in their possession, and their tactic was to try and put the burden of proof on the customer to prove it.  They even tried to get information about other bank accounts, which I'm pretty sure is overstepping the proper bounds of privacy.

As experience has taught me that CIBC is prone to this type of cock-up, I refused to change my stance and it was left with me telling the horrible lady at CIBC that I was doing nothing further, until they call me back on Monday or Tuesday to confirm that there really was a problem because I don't believe them.

Guess what?  CIBC never called back.  

Today I decided to just double-check and see what CIBC was saying now?

Here's the chart from the Credit account.  CIBC shows that had the money one day before they called me, and proves that I was totally correct in my assumption that the customer service was just being unreasonable yet again.




  

Conclusion
I'd like to be surprised, but I'm not.  

When you understand the clearing process within banks, it becomes very apparent that the people trying to squeeze money out of me in the face of the evidence presented to them have not been adequately trained on these same cycles.

CIBC and Reference Numbers Logic

Had an interesting run-in with CIBC today.    

The phone rings at 4pm on Saturday afternoon, just as I’m getting the kids down for an afternoon nap.  I’m sitting next to the kids, and thanks to the wonders of iOS 8, even though the phone has been silenced, the laptop I’m using suddenly rings.  The kids wake up and I swear like a sailor.

I call back the number after re-settling the kids.  It’s CIBC.  Their phone system says it doesn’t know my phone number and so I have to punch it in.  After a wait of about 3 minutes, a women answers the phone.  After she confirms my identity, I am informed that she has no idea why I’ve called or why they called to begin with.

What?  

I ask her to put a note on file that I don’t like being called for no reason.  After about another 30 seconds she magically finds the reason they called.  They’re looking for a credit card payment.  

Luckily, my wife had sent the payment they were looking for from TD Bank on the previous Wednesday, so I told CIBC this is just a case of another call from CIBC looking for money that is likely already in their system.  They asked for the reference number, so we gave it to her.  

If you’re not familiar with how Canadian banks work, the worse case is a Canadian tier one bank will take a full working day to process an electronic payment request, so that means TD may have processed it after close of business on Thursday and CIBC would have received it on Friday, so CIBC would process it Friday night.  Unfortunately, this is a Saturday, so it is very highly probable that because CIBC's computers don’t appear to work on weekends, it’s not going to show up on their ledger even if it was now at CIBC until Monday morning.  

I was quite confident that telling CIBC the circumstances would be the end of this.  Unless they’ve some distrust that I don’t know about with other Canadian financial institutions, you’d think that dates and reference numbers of payments would be sufficient proof of payment. After all, why give them out if they're not the equivalent of a receipt?  Next, CIBC then asked for the last 4 digits of my wife’s TD bank account.  

Hell no.  

This is the Bell Canada of banking, and they obviously thought I'd not been poked with the CIBC stick enough.  The lady went on to put the burden on payment on the customer.  Apparently, we customers are now responsible for finding out why CIBC couldn’t see the money.  

I pushed back (I’m not a bank).  
CIBC pushed again.
I asked three times to be escalated.
After not being escalated my patience ran out.  It’s hard to resolve a situation when one party isn’t listening.

Then I finally got escalated.

The new lady that took over also tried to put the burden back on me to find out why my wife’s bank had not sent money from TD.  As things got more heated, she was stating that CIBC as a financial institution cannot do traces on payments initiated by another bank.   The conversation then went like this:

CIBC:  And I’d like to just remind you sir that this conversation is being recorded.
ME:  Good, because I’d love to know why the last lady just asked about the bank account digits at TD?
CIBC?  Err. What? We just told you we can’t trace payments at another institution.
ME: So why the hell are you asking for information that you’re now claiming is of no use to you?  Something is fishy here!

It ended with me irately telling them to check their reports on Monday as there’s sweet nothing that I can do this late on a Saturday.

Conclusion
I’ve stated numerous times that the trust level between CIBC and me is very, very low.  The legitimacy of anything that I hear from them is constantly eroded by foul-ups, conflicting information and a continued sense that they’re just screwing me over.  Today was just another episode in a long and painful journey.

Look at the straight facts of what can happen:
  • CIBC will ask you for reference numbers, stating they are required to prove something is paid for.
  • CIBC now says that it can’t trace payments at other banks.

That right there is conflict in logic, so one of those is clearly a lie.  Banks should not lie.


CIBC overstepped the mark in asking for the TD account info (I’m looking into the privacy rules on this, as I think it’s not supposed to happen under the Canadian charter that the banks have to follow), but CIBC definitely shot themselves in the foot over reference numbers.  

Someone is lying to me, and I’d love to know which is the correct answer.

Thoughts on the Norway FM Radio Switchoff.

Something showed up on my Facebook timeline today, linking to an article which caught my interest.  The reason it caught my interest was I could see the three-way clash of North American culture, worldwide culture and the fact that I've worked in and around radio (and radio related technologies) for most of my life.  What is very apparent to me isn't apparent to everyone, and sometimes I forget that.

A quick primer on radio and I...

  • As a kid I would do DX'ing (listening for radio stations from other countries).
  • As an adult, I've used radio to transmit stuff over vast distances (the most extreme case was using a YAPP packet radio and atmospheric skip to transmit stuff at 300 baud from the UK to a fishing trawler that was south of the Falkland Islands). 
  • I am still an avid radio listener.
  • I was once the sole iOS developer for Clear Channel's "iHeartRadio" app (I worked on it from version 2.45 through to 3.1), which is now called iHeartMedia.
  • I've worked alongside FEMA and their EAS test a few years ago.
I moved to Canada in 1998.  When I came over, I brought my radio/tuner with me - a Sony that was made for the European market (Yes, it runs on 220 volt electricity).  At that point this radio was about 5 years old and it was the second of it's type I'd owned.  In Canada, most of it's features didn't work until about 2004-2005, which I found highly fascinating.  To date, some features still don't work in Canada because Canadian radio hasn't caught up with the early 1990's yet.

Without getting technical, most people (including Canadians) are now aware that modern radios can tell you the name of the station you tuned to - some even tell you the name of the song/artist.  This comes from a system called RDS (Radio Data Service), which has been in Europe for a lot longer than in North America.  There's an advanced version of RDS called EON (Extended Other Networks), which gave us lots more features in the early 1990s that still don't exist in North America today.  I've never been able to switch on a Canadian radio and tell it to "only play Punk" music, or have it jump to a different station if the weather forecast comes on.  

These features don't exist because if you remove choices from the listener, you can create niche stations and so in places like Toronto, where I now live, you can't listen to what you want and still have the weather every 10 minutes - instead you have to tune to a specific type of "talk radio" station where you get the weather every 10 minutes, along with forced traffic (thats a different option in RDS EON) and adverts.  Put another way, whereas European usage of radio gives you a buffet of radio to pick and choose from, the North American model gives you 100 stations and you can only listen to one at a time - and the media companies just looove a captive audience.

This illusion of choice is much like the mechanism you see in Canadian burger restaurants;  Whilst the adverts with their condescending American narratives saying "Have it your way, Canada" are telling you that you have a choice to make things exactly how you want, what they're actually selling you is either a) you can pay X dollars for a fully loaded burger, or b) you can still pay X and skip some toppings.  Obviously, this works in the burger chain's favour as everyone still pays a premium price even if you decide not to have all the toppings you just paid for.

What this broadly translates into is radio turns into these little "islands" of listeners who are being kept away from other stations - and because the audience are not exposed to other stations, no stations have to try to win over new listeners.  Radio in Toronto is crap, and radio across most of North America is bad.  Ask anyone in North America to name a famous radio station where the DJ actually "DJ's" (i.e. spins a 30 minute session of proper mixes, or introduces you to something new) and nobody can name one.  In the UK, people would say "Pete Tong", "John Peel", "Danny Rampling", "Nicky Holloway".... In Canada and the USA, this really just doesn't exist, which is strange when you consider how much music and culture is born here.  

Again, it all comes down to these "silos" or "islands"...  To really ram this point home, lets say you're a Canadian and you're sitting at your computer and you want to listen to CBC Radio 1.... you have to go to cbc.ca to listen to that.  Then you want to listen to Q107, so you go to their website.  If you want to listen to something new, you have to find a new website.  Nothing is tied together even though they're all supposed to answer to the CRTC.  

By contrast, in the UK you just fire up www.radioplayer.co.uk and every station that has a broadcasting license is available there.  Now, there's over 400 radio stations on that site, and this brings us back to the digital radio issue.  In Ontario, there's just over 500 FM stations.  In the UK, there's over 400.  So, imagine cramming 80% of Ontario's radio into 1/6th of the province and you'll have some idea of what the airwaves look like. The radio spectrum is pretty crowded!

Digital Audio Broadcasting (DAB) solves two goals:
  • Free up radio broadcasting spectrum in dense areas.
  • Allow the addition of more features to the radio that RDS EON cannot handle.
When the bulk of people move over to this type of radio, the entire old FM spectrum can be freed up for better uses.

Now, this isn't a one-sided rant, because in North America we're seeing technologies like RDS being used in equally innovative ways that Europe doesn't.  The biggest one that comes to mind in Ontario is electricity grid management.  When your Air Conditioner is being commanded remotely to shed about 10% load in a heatwave because we're running out of electricity, it's RDS radio technology.  

This is really a culture thing;  Norway switching off it's FM radios will be shocking to many people, especially to those who didn't know that many European countries have already done the same with TV.  For instance, the UK switched over three years ago.  In Europe it's normally referred to as DVB (Digital Video Broadcasting), and a quick look down this list will likely shock the average Canadian or American into realising how far behind things are here.  I have always found this interesting.  I know what's going on as well, especially in Canada where two companies run most of the media and also happen to own the cable and broadcasting networks.  

It's a money thing.  Why give the people choice when you can keep them ignorant and gauge them for money?

Cyber Crime & Fraud In Canada

In this post, I'm going to get something off my chest that has been a long time brewing... in fact, it's been brewing for years.  The subject is about Canada and cyber-crime and fraud prevention where computers and law-enforcement collide.

If you don't know already, I work in IT.  I'm a programmer by trade (for the past 7 years I've concentrated on iOS, but there's 20+ years of Windows developer mileage under this bridge before that).  My code runs in everything from ship inspection systems to SuperMax prisons to the Special Organised Crime Agency (now the NCA) and national banks.  I am JCP certified and I'm found in NATO handbooks H4 & H8.  In short, I'm a registered "good guy" with a vested interest in doing the right thing and maintaining my reputation as trustworthy.

So, onto the story....

In Canada, just as anywhere else, there's two sides to cyber-crime and fraud; There's those with the intent to prevent it and those with the intent to commit it.  Just like in most other civilised places, the legal system tries to protect people from computer related crime - in Canada we have the "Criminal Code Section 342.1" which tries to draw a box around what you're allowed to do and not allowed to do.  So far, everything seems cut and dried and nobody should be surprised by what I've said.

When it comes to fraud prevention, various layers of government and law enforcement inform the public that they are here to help, and the legal framework/laws and public education programs would lead you to believe that you are very well protected in Canada.  The reality is this apparent protection is a double-edged sword that is often as likely to prolong your exposure to fraud as it is to protect you from it.

I'm no expert in the world of cyber-crime/fraud, but I understand way more than the average person - and in the UK and the USA, experience has shown that when I try to help an organisation with a problem, people listen to me... except in Canada.  I've had conversations with Andrews Air Force base about the finer technical points of Air Force One, discussed iPhone-based Missile Impact mapping technologies with Fort Bliss by the White Sands Missile Range and everyone knows I'm a good guy who is on the same side as them.... then I get on the phone to Bell Canada one day to report to Sheilagh Malloy (their privacy bod) that one of Bell Canada's customers has been breached and needs rescuing from a very real chance of identity theft, and demonstrating this to Ms Malloy resulted in the aforementioned section 342.1 rules being read back to me and telling me to never go into Bell's systems again.  

That experience was several years ago.  Amongst the many things I learned in that conversation, I saw what I thought was a blind spot for customer safety and data.  I followed that hunch and a year later, I started a disagreement with Bell Canada about runaway customer data involving my own records that I was now looking into.  

Structuring my argument according to what I'd thought I'd learned in the previous conversation, the disagreement was "resolved" in a stale-mate with Ms Malloy so she'd think that she won her side of the argument about Bell's privacy policy because she didn't have to back down.  Because I'd pushed her into a stalemate position where I remained "dissatisfied" she had no choice but to gave me the escalation path necessary to go to the Privacy Commission of Canada, and this gave me the "green light" to go after Bell Canada's third party link with Yellow Pages Group because it involved them too.  Of course, when I asked YPG if they were willing to stand shoulder-to-shoulder with Ms Malloy at Bell Canada and her position on my data, they collapsed faster than a wet noodle and undermined what Bell Canada had argued.  

Thus, I had successfully secured my own data, and confirmed what I suspected the first time round was blind spot with Bell Canada.  Of course, once you know there is a problem, it's not hard to go looking for signs of it.

Watching Bell Canada customers get compromised is fairly trivial.  In the same way you can watch looters steal televisions from a shop across the street, you just watch the information appear outside of Bell - you don't need to go into Bell Canada's systems, in the same way you don't need to go into a leaky pipe to see that it's leaking.  

You can set up Google to notify you when a breach occurs, which means you're no longer violating Canada's Criminal Code section 342.1 because you're not accessing that data - instead someone else is telling you that data is now available - and if you're not accessing/viewing/transmitting/storing it, then you're not breaking the law.  A bonus to this, is we've gotten ourselves an accidental security canary because we can infer what Bell Canada failed at, and as long as the signals keep appearing that there's a failure, you know Bell Canada hasn't got it's act together.

What I'd like to do is help the people who are almost guaranteed to become victims of identity theft, fraud, etc.  Of course, this means reporting it and when you report it, you need to provide evidence, and under the rules of section 342.1, I can't handle that data or show that it compromises a customer by accessing their details.

As you can guess, this is very frustrating.

So, what are my options?

  • I could talk to Bell, CRTC, etc, but Bell Canada would launch a law-suit against me if I then went on to prove the problem exists because it means proving you can access compromised customers in their system.
  • Let's imagine I want to talk to the Canadian Anti-Fraud Centre:
    • You go to login here (Link) on a Mac and the RCMP securekey login fails...
    • You downgrade to Windows and login, only to find the CAFC requires specific information that you can't provide.  They have no "Contact us for something else" option.
  • I can't deal with the police, as no proof of a crime has happened yet, and again showing that the crime is likely to happen would require me to step over the law and put myself in danger when showing how and where.  

What we need:
Canada needs a program where trusted individuals can demonstrate to law enforcement that there is a cyber-fraud problem and help members of the public to be alerted when it can be proven that they are at risk from fraud/identity theft/etc.  The program should span customers of banks, too, as this is another problem area.  Finally, these whistle-blowers should have immunity from section 342.1 and have no further legal ramifications for cooperating with law enforcement to help the general public become safer by the people who dropped the ball in the first place.

In short, it's my belief that we need a mechanism whereby people can be protected from criminal activity, without those trying to help law enforcement identify the problem being penalized.  Where we stand currently is the very same mechanism to stop cyber-fraud now stops anyone from proving when you are at risk of cyber-fraud.  Of course, those who disregard the law are free to do so because they're now effectively protected by this catch-22 situation.
