If you suddenly start receiving emails from a friend saying they are stranded in London as a result of the Icelandic volcano eruption and the cancellation of thousands of airline flights that followed, odds are your friend's email has been hacked.
The scammer says to contact the sender for instructions on where to send the money via an email address that looks like a gmail address but actually is slightly different. The version I've seen looks like this: John.Doe@ymail.com.
My sister-in-law's email was thus hacked earlier today and all of her friends, family members, professional associates and other contacts are now calling to ask if she really is in London, needs money, etc. It's a pain and the worst part of it is knowing that some number of the people getting the fake email will respond to it.
Is there such a thing as the Cyber Bureau of Investigation?
