Link: You are my victim
The result was a gross profit of over $50,000 for two days of a campaign with no hacks, no compromises of systems, nothing but an email message with little to no risk of the attacker being caught. The only cost to the attacker is a couple of open mail relays and a list of email addresses and passwords from a years old attack.
Without reviewing in more depth, we can conclude that the person in question made at least 11 Bitcoins ($77,000) from this campaign and possibly as much as a million dollars for a month’s worth of sending junk mail.
Almost unbelievable and scary numbers.
