Luckily, there’s plenty of advice and guidance available – often slanted particularly towards our demographic (ie oldies) …
Those two sites are particularly easy to follow and understand, but others are equally informative and targeted. Your bank probably has guidance which it publishes online and which is accessible to everyone, not just their customers …
I’ll return to further information, guidance and references at the end of this post, but first we need to look at a few issues, discuss some terminology that’s widely used and try and tease out what’s really important, and what’s just an inconvenience and then it’s up to you to judge where you find yourself on the scale of …

Terrified -> Apprehensive -> Sensibly Aware -> Relaxed -> Unconcerned

First let’s distinguish the difference between online security and online privacy. These are two different issues which are however linked. Sometimes you have to relinquish some privacy to receive a service – unless you choose to pay for it (and I’ve long been an advocate of paying for services if they do a job that is necessary); exactly how much privacy are you prepared to relinquish? Security on the other hand is an absolute – you should not be prepared to accept less than your very best efforts . We’ll deal with that in the third part of the post.

How do you relinquish your privacy, and how much of a loss of privacy is acceptable?

Some services could not be offered without income from adverts, or paid-for advertising – eg Facebook, Twitter and Instagram; and some eg Google and Amazon track and provide information to resellers if you don’t block them from doing so. As an example of how much value Google sees in getting knowledge of what you’re doing and where you’re doing it, they pay Apple up to $20bn annually to remain as the default search engine for any browser that’s running on an Apple device! Sometimes you may click on a link and have been asked whether you wanted to accept cookies – what exactly are they, and what do they do. This article from Norton explains what they do quite well … Essentially, they record what you do on a website so that when you return to it some of the settings are remembered and applied. Cookies do however also have a downside in that some can also act to track your activity once you’ve left the site. For that reason, you should disable in your browser the ability of third-parties to glean information from a cookie, and also to prevent them tracking your activity once you’ve left the site. You can at anytime, clear the cookies from your browser, and indeed on some internet browsers set them up to delete cookies when you leave (close the window) the site. If you use Firefox as your browser it will alert you the first time you go to a site that it is using a Fingerprinting cookie itself. For instance from the Norton site above … … this is a nice feature, and should not be confused with the rather more annoying GDPR pop-ups which almost force you to accept because you can’t be bothered to check the detail that some sites force you to go to in selecting which cookies you want to store. I often just stop using that site rather than read through the options, or alternatively just click “Accept” and hope for the best!! Not exactly the privacy control that was envisaged when the legislation was enacted! Another thing you should consider is whether you want adverts to be shown, or not. You might get a request to enable adverts when you visit a site, the answer you supply will be held in a cookie in the browser – that’s how cookies work. Firefox, Brave and Microsoft Edge, by default, block most, if not all, adverts. These are often annoying and having a browser that blocks adverts, or if you use Chrome – using an ad-blocker like AdBlock Plus often makes for a more “pleasurable browsing experience” by limiting the intrusion you might feel upon your privacy.

Which brings us to browsers and search engines

Search engines are not created equal! Whilst Google is often thought to be the same as the internet and is often mistaken to be an internet browser itself, it is in fact just one of a range of possible search engines that you can use to look for information on the internet. It uses a platform called Chromium to display the results of its searches to you through a browser called Chrome. However, other browsers – Microsoft’s Edge, Brave and Opera all use the same underlying Chromium technology – the difference being they don’t track what you’re doing “to present the content that most meets your needs” (Google’s philosophy) and in some cases (eg Brave) they can actually prevent tracking of your browsing history. I use Safari – which on Apple is my default browser choice, but otherwise I would use either Brave or Firefox as my internet browser. So what safe and private search engine could you use as an alternative to Google. I use DuckDuckGo
… but others I could have used might have been Ecosia, Bing, Yahoo or another one you might choose from this article or the list of other articles at the end of it …
There are many specialist search engines (as explained in the above article) that can give you much better, and more targeted results than a broad-spectrum Google search with the priority of results returned by relevance, not payment received by Google. Finally, no discussion of Privacy can ignore Social Media and Facebook in particular. These applications, if left to their own default settings, are effectively personal information mining engines. They grab what information they can from you, and sell it on to whoever is willing to pay for it; or are indeed the platform for data mining, vis the Cambridge Analytica affair. Recent enforcement of data privacy legislation by the EU on Meta has resulted in them being hit with massive fines for breaches of GDPR law by Facebook, Instagram and WhatsApp. Online retailers are not exempt from this and Amazon for instance has a wonderful record of your browsing history! Are you sure you know what it’s doing with that information? So look at this table taken from a recent Which? supplement – Staying Secure in a Digital World – and just check whether you need to change your settings if you use any Social Media apps …
So that’s Privacy dealt with.

Should you be frightened?

The take away message I want you to have is Frightened – no; cautious – yes! Online banking is very secure – a recent survey in Which? produced the following scores …
… plus you are protected and most of the banks are increasingly opting to adopt an online and mobile guarantee to refund you where you’ve been the innocent victim of a fraud. Here for instance is Barclay’s “Online and Mobile Banking Guarantee.” They really don’t want to shell out money, so they are trying to educate us to be wise to scams. So let’s take a scam test
Banks are also often supplying software free (or at reduced cost) for you to install to protect your machine, to protect you from fraud – and of course themselves from having to pay out! I was recently offered a piece of software called Malwarebytes by the NatWest and although I have an Apple Mac computer which are well known to be relatively secure from Viruses, Spyware, Trojans and other malware, I installed it. I was pleased to note that I didn’t have any malware on the machine. Surprisingly you might think … it’s safer to use the mobile app on your phone, or tablet to do online banking and retail purchases than a web browser. This is because the app on the mobile device has to be verified by Google for Android (Google Play Store) or Apple for iOS/iPadOS (Apple Store). Whereas a browser could be infected, or compromised with malware. [That’s something I’ve learnt whilst preparing this post!!!] When you’re out and about and NEED to do an online transaction from your mobile – use cellular rather than WiFi. The latter can be really open to “sniffers”. [I must admit I try to avoid doing online transactions when away from a domestic network.] Alternatively consider buying and installing Virtual Private Network (VPN) software, such as NordNet so that you can use the free public WiFi in a public area. You can find out a whole lot about the range of scams at the NatWest’s Security Centre. However the most scary scam I’ve been made aware of is one that befell a member of my family when they were distracted sufficiently to become the victim of SIM swapping.
I’ve discussed this with you before and you can  read the updated post here. I also covered this issue in another post which involved stealing a phone, to obtain access to your identity and commit fraud, and we covered the even more disturbing theft of a credit card with the complicity of the US Postal service to obtain a SIM in a recent meeting as well.

What should you do to protect yourself?

Some of these pieces of advice are really quite straightforward, but some require some intervention by yourselves.
  • Keep your operating software up to date. This is particularly true if you’re a Windows user, and even more true if you are still running an older version of Windows than Windows 10. If you’re using Windows XP, Windows Vista or even Windows 7 you should seriously consider disconnecting your machine from the internet because even if you’ve got anti-malware software running this is probably not protecting you against the latest threats.
  • Install anti-malware, or anti-virus software, particularly if you’re a Windows user. Don’t pay more than you need to. Windows Defender from Microsoft is Free and for our demographic relatively undemanding and unsophisticated users, more than sufficient. Keep it up-to-date as well! [As I said previously, your bank might be offering free software as well.]
  • Keep the software you use regularly up to date as well. Consider removing any software from your machine that you don’t use – this is because software vulnerabilities are discovered sometimes quite a while after the software was first released. It will also save you disc space!
  • Be cautious over installing extensions into your browser. These are often extremely useful and valuable tools, ie password managers, Dropbox, note taking, Google Back up and Sync, but if you don’t get them from the official sources then you might be importing vulnerabilities, eg spyware and trojans to your system.
  • Very seriously consider logging-out from social media and other retail sites when you’ve finished using them, especially Facebook, you just don’t know what tracking and logging of what you do, even where you are, if you leave yourself logged in on a mobile device.
  • Free software is both a boon and a curse. Only download open source software from a reputable site such as Softpedia, and never try and get proprietary software for free. Read this article about Free download sites if you want to know more.
  • Remember the golden rule 1 – if it seems too good to be true, it probably is, so steer clear!
  • Remember the golden rule 2 – don’t speak to strangers (an oldie but goldie that one); in other words if you don’t know where an email has come from – ignore it; if the website address looks a little strange – do an internet search on the company or organisation to check if the address you’re looking at is a spoof of the proper one.
  • Have more than one email address. Use one as your personal address, then use other ones that you can “throw away”when you need to register to a website, but you’re unlikely ever to go back to it again. Or have an email address (UserID) specifically for online purchases. Splitting things like this reduces the risk of you being the victim of fraud.
  • Seriously consider using an email service that is NOT connected to your Internet Service Provider (ISP). If you decide to change your ISP, and you should review them periodically, then you will have real problems if your email address is linked to their service!
  • You’ve got Spam filters running? Of course you have – but you better check! Probably your ISP, or email provider (eg Gmail, Yahoo, Microsoft Outlook or Hotmail) is filtering out what it thinks is spam, but occasionally some gets through. If that’s the case then you can always look at the real sender of your message. Take a look at the examples below …
You can also apply filters to divert incoming email into different folders in your email system. That reduces the amount of Junk that you need to review. [I’ve also advocated using the “native” email application for your device rather than rely on the web-based service the email provider has. Thus on a Windows device – use Windows Mail (or Outlook); on a Mac use Mail. You can then easily synchronise your email between devices from multiple email accounts. Tidy!]

So we come to Passwords …

… this is the point at which you need to consider intervention and changing your behaviour! You might also need to do a fair bit of work, but it’s worth it if you want to have a secure internet experience. Let’s just see what using an insecure Password can lay yourself open to. Type in the word Password, or ABC123 from the link above – frightening eh!?
The most common password I use – and I know I shouldn’t reuse the same password, but I am human – has not been discovered on any pwned site. Phew!
What about the combination of your email address with your password – has that been “pwned” (ie stolen through a data breach)? Try typing your email address into the link above.
Oh no! I’ve been pwned … but it was a long time ago and I’ve changed my password many times since then!
Ah! That’s better – my “throwaway” email and passwords are “safe”!
And if you want to see a list of which websites have been breached, it’s alarmingly long! So … use a unique password for everywhere you sign on. There’s lots of tricks to achieve this; some of which I wrote about in a post quite a long time ago …
… but the real change of behaviour is to use a Password Manager – again I wrote about this a little while ago and linked it to using Two Factor Authentication, which is also covered in the same post …

Password managers

I still use LastPass, but as a back-up and archive of my old passwords. I now use Keychain as I only have Apple devices (as do most of my family, and so it makes sense to use a system that is linked to the hardware I use. Other common password managers  are Dashlane and 1Password. Please make up your own minds after reading some Reviews and seriously consider using one.
An authoritative article on using Password Managers is provided by the National Cyber Security Research Centre. They also give an opinion on whether you should use the browser offered option to save your passwords.

However … the future is Passkeys

The major tech companies – Microsoft, Google and Apple amongst them, have been working in alliance on a project called FIDO that will mean the combination of UserID and Password can be consigned to the waste basket. This article explains what they are, and what it means for us really well. Although Apple stole a lead, announcing their implementation a year ago, Google has now launched it’s implementation, and this article describes how to set them up on your Google account. Microsoft also allow a password-less way forward, but I’m not clear on how to set it up – not being a M$ user. On Apple – here’s how you set up Passkeys on your iPhone, iPad and Mac. Another reason why I chose to move from LastPass to Keychain. Whilst if you’re a 1Password user, you can combine your legacy use of a Password Manager with Passkeys, and these will also work much better together on your iPhone. Watch out for an announcement shortly! [NB It is possible to move between password managers, ie from LastPass to 1Password.] And that’s about it for this year. We can look forward to much more about Passkeys in the coming 12 months; much more about GDPR and how the UK government’s online security legislation is reviewed (and hopefully revised) before implementation; much more about “big tech” and corporations re-acting to whether they are responsible for content, or are just a platform providing a service, rather than a publisher. Interesting times!

Online banking and shopping – 10th October 2019

Welcome & Boot-up
Introductions for the last time!
What do you want / expect from the Group?
Please tick your attendance, pay £1.50 and agree that you want to join the “Thought grazing” website I run where the notes of the meeting are posted, and if you are interested in joining a WhatsApp Group.

For those who’ve expressed an interest in “Thought grazing” and establishing a WhatsApp Group, I’ll send out an email following the meeting with UserIds and Initial Passwords for new members. [You can change your password if you want to – I’ll write a post that explains how you can do that.] The Password for Protected pages on the website is the same as everyone’s initial UserId Password, namely – Ca3rdyddU3A
Does anyone have any difficulties in connecting to the Thought grazing website?
Does anyone want to join the WhatsApp Group but is unsure how to do it?
[Note for self … I need to add member to Contacts on my phone, then I can see them in WhatsApp to add them as a member of the Group. Easy when you know how … duh!]
Incidentally Paul has written a post detailing how you can add WhatsApp to a Tablet.
Do we all know the difference between Google and an Internet Browser?  – Don’t be shy. This is perhaps the most important thing to be sure about before we go any further. Two links to look at – Just google it … and the notes from the first meeting last year.
What’s happening to Digital Projects? Well the first one has been announced, it’s a re-run of a Digital Photography course using Adobe Lightroom and the first session is next Wednesday at Cornerstone on Charles Street at 10:00am.
Which brings me to our webpage on the new website, has anybody other than Paul and David had any ideas? Paul has suggested this for the photo – https://pixabay.com/photos/computer-laptop-work-place-mouse-2982270/ – seems a good one to me! David suggested a photo (at least on the page) of Turing’s first computer; or it could be Leo – the one at Lyons Coffee; or even both!
Any other ideas?
Visits. We agreed visits to the Barclays ‘Maker Space’ which Mario will arrange for us, see details below …
In addition, as part of our community commitment,  we have also opened a new office in Cardiff designed to help businesses grow and start up in Cardiff. Great for budding Entrepreneurs (which statistics show can be high in the over 50s)  and inventors. Part of the Eagle Lab office hosts  a “Maker Space” that houses laser cutting, vinyl printing, 3D printing, electronics equipment including soldering etc. It has a distinctly digital feel too with a really switched on Engineer running the lab. We can host groups there and would be happy to chat with your Digital Projects group and your Science groups coordinators, to discuss with them what is available there and whether they would like to bring members along to take a look at the facilities, or host a meeting there. Please feel free to ask them to contact me and I can discuss what they need, what we have, what we can do to support your members.
… in the approach to Easter, and also a visit to the new BBC Centre after Easter.
Fred has offered to contact Brains and their new brewery at Cardiff Gate for a visit before Christmas.
I was unsuccessful in my first attempt at getting a visit to the Computer Centre of Cardiff University, however a second request targeted more closely at a tour of the Machine Room was successful, so I’ve said I will try and arrange that after Christmas.
News and other issues raised
Renee asked about opening compressed files in emails on an iPhone. We got some way to solving that one, but agreed to take it onboard as a conversation on the WhatsApp Group. I must confess to having forgotten about this – apologies.
I’m convinced there was something else that I’ve forgotten, can you help me?
Finally Catalina – the new operating system for the Mac – was released this week (as expected). My advice, as ever – and this is true for Windows as well, is to wait – let others suffer the pain, rather than you, and as I’ve detailed before there may be issues for some of your apps. I’ve switched-off Office 2011 already as my default app on my Mac for opening Microsoft Office files, it’s now the Apple programs that open these for me, but you could chose Open Office, Libre Office or Google Docs – they are all compatible with the .docx, and .xlsx file formats. Here’s how you change the default apps to open a document for MacOS …
These screen shots are taken from my iMac running Mojave, but they should be pretty similar for older versions of MacOS …
To change which application a document opens in:
1. Right click on the document’s icon.
2. Choose File > Get Info.
3. In the Info window, click the disclosure triangle next to “Open with,” and choose an application to open the document from the “Open with” pop-up menu.
4. If you want all documents of this file type to open with the same application, click Change All.
The important thing for you to get rid of any vestige of Microsoft Office is to press Change All…
In my screen shots I have used Pages (Apple’s Word Processor), but you could use Open Office, Libre Ofiice or Google Docs.

Gear Guide
Has anyone bought, or obtained anything recently they’d like to tell us about? It doesn’t have to be a computer, laptop, tablet or phone – just something that’s digital, ie used a computer processor in some way?
Apps Galore
That slot in the meeting where members are encouraged to share their experience (and possibly excitement) at a new app they’ve started using for their smartphone, tablet, laptop or desktop machine.
What’s IT all about?
Not this week
Online banking, transferring money and shopping
A subject which brings fear and trepidation into most of us. Should we even consider using our computers when we need to supply personal information to “the internet”, and in particular information about our bank and credit cards.
I would be foolish to say it’s completely safe, as my story last year detailed, but taking reasonable care you should be OK.
Discussion
Online banking, debit and credit cards
Safe as long as you don’t leave your machine logged-in; you don’t use it from a free WiFi access area; and you password your machine with a reasonably strong password. The banks have recently all upgraded the process of logging-in that should make access for no-gooders more difficult.
Here’s a useful link that summarises the different levels of protection offered for credit cards, debit cards and PayPal (see below).
Discussion
Then there’s ApplePay and Google Pay – does anyone use them?
Paypal
You may have assumed that PayPal was only of use when purchasing from eBay, Gumtree or Preloved, but it can be used – when a website provides the option – as an easy way to pay for goods online, as you can tie your PayPal account to a debit or credit card. As the article quoted above mentions, PayPal has it’s own payment protection scheme, but if you tie a Credit Card to your PayPal account, you will get the protection offered by your Credit Card.

You can also transfer money (abroad as well) using PayPal by transferring the money directly to another person’s PayPal account. This is not the cheapest way of doing it as the Exchange Rates are not the most favourable, but it’s easier than transferring using your bank account. Although written by a competitor, this article summarises the ways you can send money overseas.
Discussion
Your money abroad
As mentioned above there are ways of easily transferring your money abroad of which perhaps the best known is TransferWise. It’s relatively easy to set up an account, and you can immediately see the cost of transferring money abroad compared to what it considers its competitors. You can even obtain a free MasterCard to use as you roam across Europe, the US, Australia, NZ and the UK.

Which? Review of using TransferWise
However, there’s a newcomer on the block which is even cheaper that’s worth taking a look at – Revolut. Both TransferWise and Revolut offer an app for your SmartPhone to allow you to do easy switching of money from your domestic bank to your online account, and Revolut also links to ApplePay. It’s easy to open a Revolut account, you transfer some funds to it and obtain a Visa Debit Card which you can then use in any ATM abroad, at low exchange rates and zero fees.

Here’s a comparison from Money Saving Expert of the Transferwise Debit Card with Revolut.
Here’s a link to a Which? Report on Challenger Banks and Revolut – you may not be able to see this – I have a Which? Online Account.
Discussion
Enough of Banking – what about shopping?
This could go on for a long time! Your experiences, please?
Any really good examples of a great online shopping experience?
Hints and tips:
Use all the facilities the retailer offers, especially if (like Amazon) they provide Two Factor Authentication (2FA) to protect your account; so it’s safe to store credit card details, and addresses on the site.
Use lists to save items you are interested in, but don’t want to purchase just yet; use your order history to re-order goods.
Remember, if you’ve relatives abroad you should look to open accounts with the local Amazon, or search for retailers in their countries that deliver – it’ll be far cheaper than sending it by post, but if you have to post look at this site – Parcel2Go – which you can use for UK postings as well and which you can arrange a local pick-up as well as pick-up from a local shop.
