There is currently a scammer taking over email accounts belonging to radio amateurs and asking for you to buy gift vouchers on their behalf.
If you get an email from someone who rarely writes to you or from someone you often talk with but the style is strange - BEWARE.
The story is the common one - for some reason, they are incapacitated and need to send a present to a family member and need your help as they cant do it themselves.
These emails are usually the result of ID theft either directly or from a website where the person who is “supposedly” sending the email has an account.
Often the scammer will use the same “signature block” so it appears to be coming from who he/she says it is.
If you have a way to contact the person via phone (OR RADIO) to tell them please do so, so that they know what is going on and can see if they can cancel their email account (or Twitter, or Facebook, or WhatsApp or or or …) to stop the fraud.
If in doubt, on no account give any money in any form in response to these emails.
