Online fraudsters are trying to lure Australians with fake celebrity endorsements and investment tips.
The number of so-called ''pump and dump'' scams being reported to the financial regulator has soared recently, with older Australians appearing to be a key target.
"We suspect scammers are deliberately targeting Australians nearing retirement," Australian Securities and Investments commissioner Alan Kirkland said.
"They know many people in this age group have accumulated retirement savings and are looking for investment opportunities."
The scammers use social media and messaging apps to promote dubious money-making ideas by impersonating well-known experts or celebrities and financial institutions.
Fakes use well-known names
High-profile economist and markets analyst Tom Piotrowski is just one of those whose names and images have been hijacked to lure potential victims.
Piotrowski, who recently joined National Australia Bank's nabtrade arm from CommSec, has been a television regular, providing viewers with updates on the financial markets and the economy.
"It breaks your heart," he told AAP.
"These fraudsters prey on people who have a passing familiarity with the share market, but they don't know enough.
"I can't tell you how heartbreaking it is to think that hard-working people are having to deal with this; it's really terrible."
In the past few days, authorities have had more than a dozen reports related to pump and dump scams, with losses potentially running into the millions.
Some of the most common involve impersonations of Piotrowski, who is intent on raising awareness of their tactics.
Financial author and columnist Scott Pape, widely known as The Barefoot Investor, has also been impersonated by scammers.
Pape recently warned his readers that there were hundreds of deepfake artificial intelligence posts online offering fake financial advice. "I'm not even on social media," he wrote on his website.
A similar case involves iron ore magnate Andrew ''Twiggy'' Forrest, who's fought social media platforms over the proliferation of deepfake AI videos or ads that make it look as though he's urging people to sign up for automated trading bots or cryptocurrency platforms.
Fake tips, real losses
Unlike many investment scams - where funds are transferred directly to criminals - pump and dump schemes often involve the purchase of genuine shares traded on real exchanges, through legitimate brokerage accounts.
"Many victims don't realise they're being scammed because they genuinely own the shares they've purchased," ASIC’s Kirkland said.
"The loss occurs when the scammers sell out and the share price collapses."
A quick way to work out who you're really dealing with is to ask the person for their Australian Financial Services licence, which many scammers don't know and can be verified on ASIC's website.
According to the National Anti-Scam Centre, Australians lost $2.18 billion to scams in 2025, including $837.7 million to investment scams alone.
In December 2025, four people who used Telegram app group chats to pump up the prices of Australian stocks before dumping them at inflated prices were convicted and sentenced to jail.
