The crypto currency scam is "most certainly not new and has been running for over a year", NZME's information security manager Patrick Blampied said.
"We continue to take down the offending scam website but it comes back under new domains."
Blampied said this scam is quite elaborate, with fake crypto exchanges often set up on the back of the scams, which is where scammers make their money.
"The social media bait used to lure people to the crypto currency scam has taken a slightly different approach in this new round in that branding and company logos are not being used, so as to evade takedown notices under copyright breach. Only the familiar landing page has copyright breaches," Blampied explained.
He says we're "clearly" seeing a return of brand abuse by these scammers, which had slowed down as the Covid-19 pandemic took off.
"We have 'takedown' proceedings underway for the known domains hosting this scam," he added.
This is not the first time Hosking's image has been used by scammers.
In September last year, the Newstalk ZB broadcaster took his concerns about fake ads to Facebook's New Zealand boss.
Shortly after being used in numerous fake news scams, Hosking told his listeners in September that he was the subject of a common bitcoin scam as well, which attempted to convince unsuspecting social media users to invest in questionable online schemes.
Facebook at the time told Hosking it had removed all pages and posts associated with the scam.
The scammers typically use images of well known New Zealanders to try to trick the public.
Other individuals to have featured in such schemes include richlister Graeme Hart, Prime Minister Jacinda Ardern and former All Blacks captain Richie McCaw.
