It has been, without any shadow of a doubt, a busy few days regarding Federal Bureau of Investigation warnings concerning cybercrime. On June 30, the FBI issued an alert for the aviation industry that attackers from the Scattered Spider ransomware group were shifting their attention to this industry sector. By July 2, that FBI warning had become a stark reality as Qantas confirmed it had fallen victim to a “cyber incident.” Now, the FBI has issued a public service advisory, as cybercriminals are using social media platforms and messaging apps to target U.S. stock investors with a ramp-and-dump fraud. Here’s what you need to know.

FBI Public Service Advisory I-070325-PSA, dated July 3, has warned the general public that cyber criminals are targeting anyone in the U.S. who is investing in stocks with a ramp-and-dump fraud that is initiated through the use of social media platforms promoting investment clubs. Many of the members of these so-called clubs have, upon investigation, turned out to be fake accounts, and active members are likely to be mostly bot-operated accounts. The social media posts, the FBI said, “typically direct victims to secure messaging apps where the group operates.”

And if you are already to dismiss victims as the easily fooled, the FBI goes on to warn that the attackers are impersonating “legitimate brokerage firms or well-known stock analysts,” to create an air of respectability and, more importantly, trust. “So far in 2025, the FBI has seen at least a 300 percent increase in victim complaints referencing ramp-and-dump stock fraud from 2024,” the FBI warned, revealing just how much of a problem this has become, hence the urgent need for the advisory.

The criminals will have control over a relatively large volume of relatively low-priced stocks, and the aim of the fraud is to get investment club members to purchase shares over weeks or months in order to inflate the price. This is the ramp bit of the fraud involved. The dump comes into play once a suitably over-inflated price has been achieved and the fraudsters sell all their stock at a profit, with the investment club members left holding a fair bit of nothing at all as the price crashes.
