A previous e-mail scam is occurring again.
There is 'robot' software available that can hack into your 'address book' or 'contact list'. Each e-mail address in your list is then automatically sent an e-mail that usually states that you are in financial difficulties abroad, having lost or had stolen your wallet, passport, credit cards, etc., and, guess what, you should reply to the e-mail offering to send cash by courier or post something like a Western Union money order.
If you receive an e-mail like this, try to contact the person named at home or contact a relative or another friend of the person whose name you recognise to verify if this person really is in the foreign country mentioned. You will find that they are not!!
If anyone really does lose cash and valuables abroad they should contact the British Consulate for assistance. Credit cards can be replaced in most countries in the world. Take the banking contact numbers with you on holiday.
