A video purporting to be from infamous hacking group Anonymous has taken aim at billionaire Elon Musk after his recent tweets about bitcoin.
The video was posted to a verified Anonymous YouTube account on June 5 and has racked up more than two million views. The same account has posted two other videos, one on the US election aftermath and the other on child trafficking.
In it, a person wearing a Guy Fawkes mask and with a digitally-altered voice attacks the billionaire, referring to him as "nothing more than another narcissistic rich dude who is desperate for attention".
"It appears that your quest to save the world is rooted in a superiority and saviour complex than it is in actual concern for humanity," they continued.
It came shortly after Musk tweeted another cryptic message about cryptocurrency bitcoin.
Musk has been a vocal proponent of cryptocurrency and recently confirmed his support for it above more traditional currencies, despite some issues with bitcoin, just one of the many cryptocurrencies available.
Tesla invested US$1.5 billion in bitcoin in February and started accepting payments with it in March, but last month announced it would no longer accept it as a method of buying a car citing environmental concerns.
Both actions impacted on the price of bitcoin, the former increasing its value while the latter saw its value drop significantly.
Musk later asked via Twitter whether Tesla should accept dogecoin as a payment option, sending the price of the meme-based cryptocurrency spiking by 20 percent.
And it's that influence on the value that Musk is having that appears to have drawn the ire of Anonymous.
"Reading the comments on your Twitter posts it seems the games you have played with the crypto markets have destroyed lives," they said.
"Millions of retail investors were really counting on their crypto gains to improve their lives. Your tweets this week show a clear disregard for the average working person."
It finishes with the ominous warning: "Now you have met your match. We are Anonymous. We are Legion. Expect us."
Just last week it was revealed that Musk's social media postings had drawn the attention of the US Securities and Exchange Commission (SEC), with two warning letters sent to Tesla being publicised for the first time.
Tesla and the US government agency settled in 2018 after alleging Musk's tweet about a potential buy-out of the company was fraudulent, with both the company and Musk paying a $US20 million fine.
