We get a variation of the email below from spoofed outlook.com accounts. I've been testing various expressions and sending the email to myself from an outside source. I have the following running tally of expressions, yet the email comes through. In addtion to simply case-insensitive Bitcoin i need to catch something like *Bitcoin* as well. So far no expression blocks the email.
(?i)bitcoin
bitcoin
\bBitcoin\b
(?i)\bbitcoin\b
(\bsales\b)
Guess what, I actually know the too dirty secrets of your life. I won't explain you exactly what I came to know, I've got every detail along with me. To show this, allow me tell you that one of your passwords is definitely BlahBlah. Pay me $1000 via Bitcoin to the address 1MibcU3Bz8sQkEtZZw16gEsHgUEMRwmnAa within the next 46 hrs. I would like to make one thing clear, that I will destroy your life entirely if I do not get the payment. In the event that I get the payment, I'll erase each and every information I have with me, and i'll disappear for good and you'll never ever hear anything from me. This is the first and also final e mail from me as well as the offer can not be negotiated, thus do not respond to this mail.
