Four strap lines to take away

If it’s out of the blue … it’s not for you! Or,

If it's out of the blue … don't click through!

If you didn’t ask for it … don’t do what it says!

Quiz the caller!

Email, texts and phone calls

The problem: email, texts and the land-line phone system
were invented in the ’80s without much thought about

Email addresses, text messages and phone numbers can be
spoofed, that is, compromised, as being sent from anyone!

So it is technically possible for someone to:

There is no way of preventing this old tech from being
compromised, so … one at a time:


Firstly, a simple fear-free approach

If it’s out of the blue … it’s not for you!

If you didn’t ask for it … don’t do what it says!

… then … delete it

For the curious - another approach:

Check the domain (website name) of the sender’s address
(the bit after the @)

Email addresses can be spoofed, that is, compromised,
as being sent from anyone!

[See examples: Mail > Plusnet]


Again …

If it’s out of the blue … it’s not for you!

If you didn’t ask for it … don’t do what it says!

… then … delete it

Scam texts usually have links, check the link website
It it a website/domain you trust!

[See examples: Photos >Places]

Phone calls

Phone numbers can be spoofed, that is, compromised,
as being sent from anyone!

The problem here is that it may be a genuine caller!

So …

Take ownership of your own identity
and information … you ask questions!

Quiz the caller!

You ask the caller your questions!

I recently explained this to a lady older than me who then
said she was looking forward to having a go!

When you receive a suspect email or phone call: Don’t
only block the number but note the number and put it
in the subject line to:

Action Fraud at

When you receive an ’urgent’ communication …

‘Do it tomorrow’, maybe the best way to stay secure
… if it’s really important it will wait!
… and talk to someone about it.

Curiosity or something-for-nothing can lead you astray

Scammed: why the rich, famous and experts get duped more often than you think

[Skip this …to read at home!]

People often feel confident in their ability to detect a scam. In a series of experiments that investigated why people engage with materials that are obviously scams – such as letters apparently notifying the person of lottery winnings – we found a subgroup of people who said such letters were probably a scam but would contact the scammers to see for sure, then still back out without any losses.

A typical scam starts by exposing a victim to the fraudster’s pitch, which is designed to evoke strong emotions such as fear. Then fraudsters use persuasion tactics such as commitment (making people feel obligated to follow through on a pledge), authority (police), scarcity (time pressure), and “social proof” to engage their targets. Social proof is a term coined by psychologist Robert Cialdini to explain the way consumers will adapt their behaviour in response to what other people are doing.

Privacy and data loss

If privacy is not important to you, take a mental break for a
few minutes … !


Google is now quite hot on security, but is totally reliant on
data about its users for its advertising billions on knowing as
much about you as possible - profiling means zero privacy.

Suggestions to avoid a lot of Google’s invasive

Meta/Facebook/WhatsApp/Instagram, etc

Not only does Meta profile you to make its billions, like
Google, but unlike Google it has also had at least four
significant data breaches.

The UK Information Commissioner has gone on public record
to describe the organisation as, “Morally bankrupt
pathological liars”.



Suggestions from PCWorld:

4 Amazon Privacy Settings You Should Change Right Now, 

Jared Newman advises that changing these four Amazon
privacy settings can minimize or prevent much of Amazon's
data collection.

  2. Limit Alexa data collection

  3. Minimize Amazon device data collection

Suggestions to use instead of the above

Land Registry Property Alert Service

Property Alert is a free property monitoring service for anyone who
feels a registered property could be at risk from fraud.

You can sign up to get email alerts when certain activity occurs on
your monitored properties, so you can take action if needed.

And now for something completely different!

Artificial Intelligence - ChatGPT, etc

This is a subject on its own - a warning …

Whereas some email scams give themselves away with poor
grammar and punctuation, misspellings and strange layout …
that is all changing: email and text scams may be generated
by AI and become totally plausible! But the advice is the same!

A recent report describes how a man in the US received a
distressing phone call sounding like his mother demanding
Bitcoin for her release. He ‘quizzed the caller’ and asked her
for her maiden name! He rang his mum … she was fine. Her
voice was copied by AI from her social media posts!

Check to see if your email address has been
compromised or ‘pwned’ …
