Tech support scammers should probably just hang up the phone when a scam call goes wrong.

But one scammer took things to a new level by threatening to kill a man who pointed out that the scammer was trying to steal money.

As we've reported numerous times, scammers pretending to work for Microsoft tech support call potential victims, tell them their computers are infected, convince them to provide remote access, and then charge them hundreds of dollars to fix imaginary problems.

Jakob Dulisse of British Columbia was wise to the ruse and recorded such a call two weeks ago, CBC News reported today. After Dulisse accused the scammer of trying to install malware on his computer that would steal banking information, passwords, and PayPal credentials, things went very wrong.

"You do understand we have each and every information, your address, your phone number," the scammer said in the recorded call. (You can listen to excerpts at the CBC link.) "We have our group in Canada. I will call them, I will provide your information to them, they will come to you, they will kill you."

That wasn't the only disturbing thing the scammer said. CBC reports:

The caller became irritated, but it wasn't until Dulisse asked why the man would try to steal from unsuspecting people that the conversation took what Dulisse calls a "sinister turn." "He started getting kind of nasty and angry. "He admitted that he was in India... and then he said, 'If you come to India, you know what we do to Anglo people?' I said, 'No.' "He said, 'We cut them up in little pieces and throw them in the river.'"

Dulisse found the threats "chilling, but hard to take seriously," CBC reported.

"He was still trying to get me to do what he was trying to do with my computer," Dulisse told CBC. "He was actually threatening me as a tactic."

In the US, federal officials have been shutting down Windows tech support scam operations for years, but new ones using the same tactics keep popping up.
