No idea how he hacked into my friend's facebook. He only targeted her overseas friends, maybe hoping that we won't be calling each other all the time. He just started the message with asking if I know anything about bitcoin. I only vaguely know it's online currency but not sure how it works. He tried to make himself sound legit by mentioning her husband's name too. I was just having a conversation with her on fb last week so he'd know I'm not a random friend. He was just trying his luck with her overseas friend, one of our mutual friend was in a meeting and too busy to reply. Another one almost got scammed and was still conversing with the guy when my friend noticed the conversation happening right in front of her PC screen and she jumped in to type that it's not her. After which the hacker deleted all previous messages.
The only address the hacker gave me to send the bitcoins to looks like this "1A5km5FwKzw8eWhMrMZTHQixR9XFgGTRuq". He was giving me this other address initially "1Jj5YTgDxfzgXKe8n2ms3X1XAFhf47Tikt" but later decided to change to the first address. No idea how the address thing works.
btw, we're both females and married, so definitely no 'Hots' for each other.
I don't expect to get the money back, but this could be a new way to scam money online. It's not like the nigerian scam which preys on people's greed, nor some sob story to prey on people's sympathy, they pretend to be like a friend asking for a favor so it seems more 'believable'.
