I had 3 separate emails last year purporting to be from Malaysian Lawyers offering similar services - namely someone with the same surname as me had died and left several million dollars. The names of the solicitors were pukka (I checked this out quite simply) but the email addresses were Hotmail addresses, and I simply can't believe that a large firm of lawyers would be using Hotmail email addresses (no email addresses were listed on the Malaysian register). I simply sent copies of the emails to the (real)lawyers in Malaysia and let them sort it out.
I worked in the Telecoms business for many years and know that certain countries are out of bounds business-wise because of the endemic fraud - Nigeria, although probably the worst offender, is only one of them. One company I worked for provided one of its customers with telecoms call-cards for it's employees - within a few hours of the issue, one particular card had been used to make several hundred, concurrent, calls to Nigeria. Luckily our fraud unit was on the ball and the scam was nipped in the bud very quickly so within a couple of hours the card was blocked. The employee in question funnily enough was Nigerian and vehemently denied any wrong doing but was found out because numbers he himself had dialled using his card matched the number of some of the originating calls which were implicated in the scam.
Just be careful!
