Last month we circulated an email warning of a few recent incidents, both in the UK and USA, where fraudsters have targeted bridge clubs. A few more clubs replied saying they had been targeted, so whilst we are sure that most people would smell something fishy about it, and would generally be vigilant anyway, we thought the warning was worth repeating.
The pattern seems to be that they get the name of the Treasurer and someone else on the committee (presumably from the club website) and then write to the Treasurer asking them to pay a bill, or transfer money. They give some payment details, and then sign the email as being from the other club official.
There can be lots of tell tale signs that it isn't genuine, though at least one US club has fallen victim to it. They have shared the emails here so you can see what they were sent.
You may wish to mention to people on the committee to be conscious of the fact that such scams are being attempted, and that they should think twice before making any payments.
