A new TikTok trend has people posting their attempts to exploit a “glitch” in Chase bank ATMs that offers “infinite free money” — but quickly learning that a bank and its money are not so easily parted.

Experts say the “glitch” videos look an awful lot like check fraud — one of the oldest scams in the book.

Videos urging customers at the bank to take advantage of the “glitch” quickly took off online, prompting people to deposit fake checks for large sums of money. The glitch would credit some of the sham deposits to the customers’ accounts before the checks cleared.

One video showed people lined up outside of Chase locations in New York City, allegedly looking to take advantage of the “viral glitch to get free money,” one person wrote on X.
