I bought my mom an iPad (the largest one at the time) and bought her a printer that works with her iPad. In the two years since that, the only call that I've ever received was "Does this pop up that says 'OK/Cancel' that says my iPad is infected with a virus actually mean anything?" "No, Mom." "Ahh, ok. I didn't think so." Works like a charm.

If you install an ad blocker for Safari that will get rid of most of that as well. I have found Adguard works well and is free.

Everyone knows that such spam mails are NOT sent by the company, but by scammers. Look at the raw email header. So why is this comment on top? It seems HN got mainstream and with it the usefulness is declining - low quality comments staying on top that can be answered by common sense.

It's likely that Animats knows what he's doing. He also says that the email contains a link to the real website, not to a scam website. So, if it was sent by a scammer what's the purpose? How does it work? And if it was sent by the company, why are they sending email that looks like a scam?

The mail header entry at the point it leaves FedEx's systems and enters my website is:

    Received: from pvma00057.prod.fedex.com ([204.135.8.98]:61625 helo=mx28.infosec.fedex.com)

That looks OK. Unless FedEx has an open mail forwarder, a break-in at "pvma00057.prod.fedex.com", or DNS trouble, that's from FedEx.

Besides adblock + auto updates, tell them how some of the scams work. Show them some example screenshots/videos etc. from different areas. Enough to make them think twice about what they are allowing to run on their computer. Scammers are usually lazy, many times their email addresses, website address, or web design might give it away - so doing a few side by side comparisons may help.

There's also a lot of youtube videos that could be easier to send and less boring to go through. Ex:

Most "non-tech" people have a reasonably small attack surface, so my approach has been to try and milk the Pareto principle:

Here are some things I've found which are simple enough to implement but actually offer substantial gains. Learned mainly from helping partners and parents:

1. Move them to Gmail. Email seems to still be the primary vector for most attacks and Gmail's filters are awesome.

2. Get them on a less permissive OS. Shifting from Windows to OSX/iOS has made a huge difference.

3. Teach them a reasonable password-generating method (correct-horse-battery-staple or some such). They are gonna forget and reset passwords regularly, which is OK. I gave up on getting them to habitually use a password manager.

4. Force (coerce/bribe/cajole) them to use 2FA on critical accounts (email, FB)

5. Tell them lots of anecdotes about hacks, things I spotted in my email, etc. As someone else pointed out, you can work in a lot of useful info in a memorable way in these anecdotes.

Tech does seem to be only part of the solution (and probably not even the major part). I've been doing some gig work for a company [http://www.popcorntraining.com] that does story-based security awareness videos, mainly for corporates. They have pretty good results based on fairly small time investment by the participants.

Sadly, most of the players in this market seem to be focused on big companies at the moment, with a few starting to aim at SMEs. We've bounced around the idea of trying to help the consumer market, but its not yet been worthwhile for them.

1) Find out what their pain points are.

2) Develop or help them develop viable processes for their needs and abilities that will sidestep issues.

This involves a small amount of educating people, less than is needed for real internet literacy. The difference is it makes them literate enough to navigate the parts they actually use, without some huge burden of additional general information that they son&t really need and which will just interfere with them learning the pieces they actually need to know.

I put my mum on Linux Mint, hid the menu launcher and put icons for all the stuff she uses on her desktop, set updates to automatic and put her on a Gmail account on a domanin I own. That and a basic crash course in treat everything as suspicious unless you know it isn't has sufficed so far. If she has any doubts she just rings me but that's rare.

Main reason not to use Linux is because there’s no Microsoft Office support

My mum writes a fair bit, I switched her from Office to LibreOffice with few issues.

What really irks me is getting an email like this: Shipping account suspended Dear XXXX, FedEx shipping privileges for account number ending in NNNN have been suspended. To access and update your credit card data, log in to FedEx® Billing Online. Log in today (Button) This just screams "scam", especially since I haven't used the FedEx account in months. When I log into FedEx (not using the link in the email), my acco…

There should be a way to give a credit-card number that is automatic identified as fraud and triggers persecution when used.

With SPF, DKIM, DMARC, coupled with blacklists and the reputation system of big mail providers that's making it difficult to host your own email, it's actually quite to impersonate an email address. Try it, then see how many times you can hit a @gmail address.

I found that this does not stop one from sending emails that appear to originate from addresses like info@paypal.com as long as the contents of the email are different from known spam emails. They are not flagged by GMail at all as long as you send them from a reputable email server through services like mailgun.com.

SPF will catch these really easily.
