[US] pump and dump Whatsapp scam

In a sophisticated variation of a classic financial fraud, scammers are leveraging the reputation of global institutions like JPMorgan to lure victims into high-stakes investment traps via messaging platforms. By impersonating financial experts, these bad actors create controlled environments on WhatsApp designed to build trust before orchestrating a coordinated stock manipulation scheme. These incidents highlight the growing danger of social engineering combined with emerging technologies used to deceive potential investors.

What happened

The attack began when the victim was added to a WhatsApp group featuring a supposed financial guru claiming to work for JPMorgan. The group included numerous participants who appeared to be real investors, though they were likely bots or accomplices. To build credibility, the impersonator provided stock recommendations that resulted in small, legitimate profits for the victim.

Once the victim’s trust was established, the scammer initiated a pump-and-dump strategy. They generated urgency by predicting a major market shift and pressuring members to clear their portfolios to invest heavily in a specific microcap shipping stock, NTC. The accomplices in the chat reinforced this by claiming to invest hundreds of thousands of dollars, pressuring the victim to commit to a large purchase. After the victim played along by claiming to purchase the stock, the scammer demanded proof of the transaction. When the victim provided an AI-generated fake receipt, the scammer accepted it and continued to solicit more funds. The following day, the stock price plummeted by 90%, at which point the scammer ghosted the victim and deleted the group. Pennsylvania Attorney General Dave Sunday has warned that these schemes increasingly utilize deepfake technology and social media advertisements to misrepresent famous companies and celebrities, ultimately aiming to drain victims' bank accounts through fraudulent investment opportunities.
