Pig butchering is a newish twist on romance scams in which fraudsters build a relationship with their victims and then con them into transferring money into accounts controlled by the crooks.In these cases, however, the fraudsters convince their marks to "invest" in cryptocurrency via phony websites, and then once the transfer goes through, the crooks disappear with all of the victim's money.While the court documents remain sealed, we're told that fraudsters tricked five victims in the US between May and August into transferring their money to the seven now-seized domains designed to look like the Singapore International Monetary Exchange.Once the victims transfer their money into the deposit addresses, the miscreants move the funds through private wallets and swapping services to make the money near impossible to trace.The pig butchering domain seizures come about a month after the Justice Department unsealed an indictment charging 11 residents in New York and New Jersey with money laundering conspiracy, wire fraud conspiracy, bank fraud conspiracy, passport fraud conspiracy and aggravated identity theft, among other offenses, for their alleged roles in a pig butchering investment scheme."
